  I am puzzled with this statement: "The CPD4 does not handle CCPM helicopters or aircraft configurations that include differential ailerons or flapperons"

Could some one pls elaborate? Thanks.
-Reply from 3900Kv (322 points);
The device does not do any mixing so it can only be used with straight 1 to 1 input and output.
-Reply from nowinkk (853 points);
Means cannot be used in a CCPM helicopter?
-Reply from Runny (189 points);
Exactly. not compatible with CCPM helis (version II IS compatible) In CCPM the output is mixed between the servos. this device cannot input nor output such mixing
-Reply from Nonkey Mutz (19 points);
I have checked the manual and it does deal with mixing. As for the heli side of thing I do not know. Get the manual by Googling: fma copilot manual. Select the first listing and then choosing the CPD4 manual.
-Reply from Jimbo738 (1 points);
Only works on basic aircraft with elevator, rudder and aileron. No flying wings, deltas, or other kind of wing. For this CCPM heli you use 3 servos to operate main rotor and the fma only has 2 output so this does not work either, old heli's use 2 servo for main rotor control steering. they might work.

  Hi guys, can be used this device as inertial stabilization for FPV? Im thinking about using this device together with the Eagle Tree OSD Pro to be able use the RTH ( return to home ) function. Had anybody tried it? Thanks for reply. BR JiriT.
-Reply from Florian (5 points);
...thats one of the most common combination for fpv. But you have to set it up by trying and adjusting. It's not a "out of the box solution"... Cheers
-Reply from Shura (123 points);
it can be used with Eagle Tree OSD Pro, but may have some problems. Look it in the manual Eagle Tree OSD Pro

  Do i have to calibrate the copilot before each flight? or is it required to do this procedure only when first launching the copilot?
-Reply from Sawdust (1910 points);
I have only just ordered this myself so no real world experience it but from reading the manual you can find in the files section you have to calibrate it at the start of each days flying and during the day again if the weather changes a lot. It looks like it's a very easy quick thing to do though.
-Reply from TurboJimmy (75 points);
you have to every time the system is powered up annoying but still great for the price
-Reply from chrisjij (41 points);
if you go to the files section of this items page you will find the manual, the preflight checklist and much more usefull and correct information. if you like me have spent the money to buy this thing read the manual
-Reply from NotDeadYet (224 points);
The Co-Pilot works by using the differences in temperature between the sky (0 degrees) and the ground. You calibrate it when you get to the field and then you can fly all day without re-calibrating. Calibrating takes about 20 seconds. You don't have to calibrate after removing the power, the settings are stored. You just have to calibrate when the environment changes (like flying on a different day with different weather). You could actually fly on different days without re-calibrating but it isn't a good practice. The Co-Pilot self adjusts in the air but you want to give it a good starting point..
-Reply from __alek (53 points);
You make initial setup. Then you need to calibrate it in the field only before the first flight on that day. Or re-calibrate when wheather conditions dramtically change. So, if you go flying on satruday morning, you calibrate it and you can do as many flights as you want on that day without having to re-calibrate it before each flight.
-Reply from Shura (123 points);
You must be calibrated, if the weather changed dramatically. Small changes in the weather can be ignored. You'll soon learn by experience

  Hi, can I use this system also for a drift car or hovercraft?
-Reply from Julien (17 points);
It only detects an artificial horizon (based on different heat signatures) and can trim 2 channels to bring back the model to a stable flight. Don't think it has an application on a car or an hovercraft. Greetings

this product is only for air vehicle.

  I thought FMA discontinued their analogue thermopiles? Does anyone know if these co-pilots use the new digital thermopiles??
-Reply from Luiz (16 points);
These still use the analog thermopiles. Either it is still in production or they have a huge stock... *-) I actually like these better than the CPII for fpv as these have more authority.
-Reply from Lazuri (8 points);
absolutely not.
New copilot unit uses digital sensor with 3 wire plug. analogue thermopile sensors with 4 wire plug.
Felar Furlong (1127 points)
  good product. bought from "another" place for much more $$$. works as advertised. please also sell servo buffer, or it won't work correctly with digital receivers (when control pulses come at same time)
-Reply from JelleB (501 points);
There is no rule that all receivers with a microcontroller put out the pulses at the same time. Perhaps yours does, but it costs a lot less resources(timers) to put out each channel on its own pin sequentially. Did you measure with a osciloscope that yours puts out the pulses at the same time?
-Reply from Felar Furlong (1127 points);
no, haven't done measurement, but it behaved exactly as described at rcgroups. rx is corona synth 8ch dual conversion. i was forced to not to use in-flight sensitivity adjustment (one of three channels was already put through osd pro).
Stealth29(U.K) (27 points)
hi all
i have the mini brushless cessna 182 , is it ok to put the unit in the center in order to keep the roll balance the same or will the propeller wash affect it?,
-Reply from Stealth29(U.K) (27 points);
many thx to Sanjay from revolectrix for the following info*_

CPD4 or CPII main sensor should be positioned where the sensor windows can see all around the horizon. The sensors can have windows facing forward and backward, left and right. Or the sensor can be rotated to 45 degree angle. The sensors will not be affected by prop arc or prop wash. Small obstructions like a vertical stabilizer or landing gear will have no effect on performance. The sensors can not see through clear plastic ca
-Reply from Stealth29(U.K) (27 points);
The sensors can not see through clear plastic canopy, however. The sensors can also be mounted on the bottom of the aircraft upside-down. Whatever works best. But most important, the sensors should never be mounted in the exhaust stream. If the sensor windows get sprayed with engine exhaust, they will malfunction.

Hope this helps..

  hi all,
i got a Sapac Hawk ,Art-Tech su27 and a parkzone spitfire, a,u.w. for each is approx 750grams, would they cope with say 15mph winds with this device, i live in Bournemouth U.K and it is allways windy here, and it does seem to be getting worse every year......whats the windiest u guys have flown in with co-pilot and with what size planes?,
-Reply from NotDeadYet (224 points);
The wind is similar here. I have an aerostar that weighs about 5k. With the Co-Pilot installed and on it stays pretty flat. That's with some speed though, I haven't tried to fly it near stall speed with a cross wind or anything.
-Reply from imac1 (44 points);
You can control the level of the system's response
Also I flew triner model with winds of nearly 30 km h
-Reply from Shura (123 points);
i fly with wind almost 9 m/sec- it is very easy and stability. Sometimes the plane stayed in place and even moved back. Fly and do not worry!
-Reply from Stealth29(U.K) (27 points);
thats super, thx for the help guys, ive put it on my mini cessna, thats the lightest model ive got, the others should be no problem then,
thx again.
-Reply from lionawa (6 points);
hi I have flown a Multiplex Magister with winds upto about 15 mph.! It is fascinating to watch how the Co-pilot maintains level flight and land with ease on its own as you reduce throttle.But get your calibration spot on. Biggest fun is to fly your plane with Co Pilot in windy weather!!
-Reply from Stealth29(U.K) (27 points);
thx again , all yr advice is very much appreciated. ............ i just wonder now if Hobbyking will ever stock a MiG29/35 for me to put co pilot on!!!
Robachan (1160 points)
  Is this statement for real - " senses the difference in infrared signature between the earth and the carbon dioxide in the atmosphere"?? Can't imagine how sensing carbon dioxide would allow for level stabilization. Any tech geeks out there to help enlighten us? Anyways, this looks perfect for helping my girlfriend get into a 4 channel plane and me to fly more tricky ones. A little more info here - ***********fmadirect****/detail.htm?item=1489§ion=20
-Reply from Beaufighter (1811 points);
It says it measures the difference in IR signature between earth and the co2 of the athmosphere. Put simpler: The difference in temperature between ground and sky. It does not measure co2 levels.
-Reply from JelleB (501 points);
The CO2 has nothing to do with it, it would also work in a ,say nitrogen atmosphere. It relies on each object to radiate IR.
-Reply from Robachan (1160 points);
Can someone please elaborate on how this thing actually works? How does sensing IR signature/temperature differences make it know what is horizon level, elevation or original direction of travel? FMAdirect website says it must be mounted on the outside where it can "see" the horizon in all directions. What is this thing really doing? I can understand gyros sensing gravitational pull. I can't even begin to wrap my head around what this thing is doing.
-Reply from Terje (12 points);
The earth inner consist of hot magma that radiates. The universe is almost 0deg kelvin. So pointing up = cold, pointing down = hot. With 4 sensors one seek the attitude that gives the same temperature on all 4 sensors, that is level. Upside down is also level, but as that will require inverting servo direction (that does NOT happen) the air craft will quickly rotate back to normal flight. Quire simple. But on a cold winter day with snow there can be problems. Also remember to calibrate every day. T9
-Reply from JelleB (501 points);
Terje explains it quite well. This thing is like a very unfocussed IR camera. When it sees a lot of (warm) earth (when diving or banking) it gives a larger signal then the opposite sensor, which sees a lot of (cold) sky. The two signals are compared and the outcome tells you how far from level you are. Add a microcontroller to process the input and output of servo signals. BTW: a gyro does not sense gravity, that is what an acceleration sensor can do. A gyro measures rotation. You can use that alone to stabilise a plane, but the drift in the sensors will cause errors over a longer time. Thermopiles like this one don't have accumulating errors, but they are sensitive to things like a tall tree next to your flying field, which may bank your plane if you pass too low/close.
-Reply from Robachan (1160 points);
Thanks guys. Those explanations help a lot. I also found an FMAdirect support doc, The FMA Flight System. Google it or if this works - ***********fmadirect****/support_docs/item_1110.pdf Perfect quote from it is "In the infrared spectrum, the Earth is warm below the horizon, while the sky is cold above the horizon." Next, I thought that would only be one axis, but now I realize on an aircraft, it would account for both elevator and ailerons, but not rudder, so no directional control. So not any 2 axises, it must be those two. Would that be a correct assumption?
-Reply from Robachan (1160 points);
JelleB, instead of a gyro "sensing" gravity, I meant to say that a gyro is affected by the force of gravity. One quote from Wikipedia - "The torque on the gyroscope is supplied by a couple of forces: gravity acting downwards on the device's centre of mass, and an equal force acting upwards to support one end of the device."
-Reply from Beaufighter (1811 points);
Yes, Rob, not any 2 axis, only elevator and ailerons (known as pitch and roll axis), and only one servo output for each. A real gyro will work at 0 gravity (it works on the principal of inertia), but yes again, here on earth gravity is one of the forces that will affect it.

Re: Using Co pilot on mixed channel aircraft I own a Skyfun (2channels for controls which are mixed channels 1 ch for thrust) and I’m looking for a device like Co pilot (CPD4) or Co Pilot 2 (CP2). On the sales page for this device it says that “ The CPD4 does not handle CCPM helicopters or aircraft configurations that include differential ailerons or flapperons”. Which I assume that means my plane that has mix channel. However I go to the FMA website and download the manual (***********fmadirect****/support_docs/item_1126.pdf) for the CPD4 and it has a section (P.8&9) on how to configure “ an on-board elevon mixer”. They use the example of an electric flying wing which is a similar set up to my plane. Two questions: 1) On review of this information, do you think that this will work on my plane? 2) Do you think that FMA (makers of CPD4 and CP2) are just trying to sell their more expensive product???
-Reply from JRBeaman (318 points);
If you do NOT use transmiter mixers, you can use this. For Alerons, I use one chanel and a polarity switcher for one side, and it works just fine. Rudder turns left and right, and only effects roll if your plane is designed for it. (Most do it a bit anyway). If you have a wing, you need to use onboard mixers, and not your transmitter. If you can't/won't then this device will not help you.
-Reply from Jimbo738 (1 points);
look at diydrones website and lot of geeks explain the infrared sensors. Tricky planes only in normal config because it does not handle delta wing or flying wings.

Aileron and Elevator servo's plug into it, then the plugs from this go to RX, then configure as per instructions. Simple as it can get really.
-Reply from smolder (7 points);
É simples de ligar, no próprio equipamento já vem todas as indicações de ligações. O plug do servo é ligado de um lado e tem uma saída pro respectivo servo do outro, que já sairá estabilizada.

Don't think so. More info on DIYdrones as they use them for autopilots and they say they don't work around mountains.
Greet Jimmy
-Reply from NotDeadYet (224 points);
I have one and I live near mountains. If you are less than 100 feet from the side of the mountain or cliff, the Co-Pilot will have trouble. Otherwise it self adjusts. You can fly it in a mountain valley without any issues as long as you keep it 100 feet from interfering objects (including trees etc). In fact it has more trouble with intermediate interferance (a tree less than 100 feet) than it does with constant interferance (a cliff at 100 feet).

  Can use for a quadricopter??
-Reply from Dinel (22 points);
This is used to control servos, not regulate motors on a quad (it's how a quad controls pitch and roll - on a plane/heli pitch and roll is controlled via servos). For a quad stabilization you can use a quad solution you will find in the multi-rotors section of the store. Pace!

  Have the unit on a big Zlin - works perfectly. I do have a question about auto trim on / off though. I've read the various instructions but still fail to understand the way the auto trim works. All the models have flown without the auto pilot and are trimmed on the transmitter for balanced flight. If auto trim is selected does it change this initial trim in any way? Does it retrim previous settings? Does anyone have an answer or the knowledge to give an explanation? Thanks guys bini

You may have servo jitter or "hunting" when used in combination with very-high-speed digital servos. When interfacing Co Pilot CPD4 to a PCM or certain 2.4 GHz radio systems,you can use a servo buffer

  After having an onboard camera on a plane and watchig the video I've thought that one of these would be the trick. In flight the plane is always jerking this way and that. Some sort of stabilization would be great.
-Reply from NotDeadYet (224 points);
I don't know of any stabilization solution that would keep an airplane perfectly level in the wind.

You can try to dial in the Co-Pilot and your plane to make it a bit more stable though. If you have a spare channel (especially with a POT switch) set up the CP to use that channel so you can adjust gain in the air.

Also, you may want to decrease the throws on your ailerons so that the plane rolls a bit slower.
-Reply from tomukas1990 (12 points);
Together with co-pilot you can use and Gyro. Adds stability
-Reply from LUNDY (533 points);
As long you don't interfere the flight with your steering stick its flying rock solid . Its adjustable from your transmitter, or from the unit itself what ever you like,start with low sensitivity or the plane start to wiggle like a goos . Just make your turn and ease of the stick and its stable all the time also in keeping altitude . I like it more than a Gyro .

-Reply from Ditman (44 points);
David, it refers to an onboard mixer. These are small devices that do the mixing instead of the radio Tx. They are installed between the receiver and the servos, so that your Radio send normal signals for elevator and aileron and these devices do the mixing and move the servos accordingly. They are often used by people with non-digital Radios that don't support mixes. HK sells a couple of such devices.

No, unfortunately the CPD4 does not handle configurations that include differential ailerons... Do you really need the differential ailerons? Otherwise you could still use this in combination with a V cable.

I have both. Both have external sensors. FMA CP2 has X/Y axis IR earth horizon stabilization - obviously will not work indoors. Flymentor has gyros for X/Y and a camera for "position" mode. FMA CP2 has a built in configuration routine. Flymentor needs a computer and the Helibal software to configure."Better" depends on what model you intend to stabilize. Both will work with Aileron Elevator Throttle Rudder AETR airplanes but FMA (AETR and Elevon)is optimal. Flymentor will be overkill as "positi

  hi, dose it work with a mode 1 tx futaba 6ex with a blade 400 helicopter? has it been done?
-Reply from NotDeadYet (224 points);
The Co-Pilot works by sitting between the reciever and the servos. It watches the signals sent to the ailerons and elevator and doesn't care what sent them, so the transmitter is irrelevent.

Your helicopter, however, is a problem. I believe the Blade 400 is a CCPM which means that (in most cases) the channels need to be mixed before they get to the heli. Therefore, the Co-Pilot will not work unless you have an onboard mixer to take care of the CCPM.
-Reply from Shura (123 points);
I agree with this
-Reply from Starving Studios (71 points);
you need the other fma copilot for heli copters, this barely works on airplanes without a v tail mixer, but does work well once it is set up and you get past the retarded manual.

  Ok so i want to use this system with Eagle Tree's OSD Pro, and the return to home function that accompanies it. Obviously the OSD Pro does not have gyros or any other stabilizing system so for another safety net i would like to add this system in. 1. would this work with Eagle Trees OSD Pro and 2. is there some way to turn this system off/on via a spare channel during flight?
-Reply from NotDeadYet (224 points);
It's hard to see in the pics, but there are three inputs for only two outputs. The third (RMT) is for the on/off switch. Actually, it's a sensativity switch, so if you put it on a channel controlled by a pot switch you can adjust in flight. A two or three position switch will function as on/off though.

I do not think servo brand does matter. This unit is connected to your receiver and controls servos just like you control them with TX sticks. If your serovs work of when controling by hand, then they should work ok when controlled by the FMA.

  I have just recently fitted this to my Pitts (not flown with it yet). In setup mode it operates the control surfaces beautifully at full throw, but when I switch to normal operation all ground tests have had minimal throw (as in only move control surfaces a few mm). Have I done something wrong or is that normal? All IR windows are unobstructed and clean.
-Reply from NotDeadYet (224 points);
I don't have any technical data to post, just my experience with this issue. When I first set up my Co-Pilot it did the same thing, very short throw especially on the ailerons. Since I was already at the field and had it set up on a switch to enable in the air, I flew the plane anyway. Once up in the air fairly high I flipped the switch and the plane self stabilized without any problems. The field where I fly is always windy too, so it worked very well. I think that either the plane doesn't need that much throw to stabilize or the temperature differences between ground and sky are more pronounced in the air. Either way, it works. BTW, no matter what I would never fly any flight stabilization system without setting it up on a channel so I could test the setup high enough to not risk the plane.
-Reply from DingDuck (4 points);
Cool... thanks for the reply. I had already bound the sensitivity control to a dial on my TX for exactly the reason you stated :) Once I get some altitude I will play with it a bit and see what happens... just waiting for a nice dry sunny day when I'm not too trashed from work!

  Hi everyone, I am a beginner and wonder if you should Flymentor or Co-pilot 2? Thank you.
-Reply from NotDeadYet (224 points);
I don't have a Flymentor, but I do have a Co-Pilot.. From what I've heard the Flymentor is just for helicopters as it compares photos of the ground to control stabilization. The photos are concerning as well. What if there's snow on the ground or you're flying over a lake? The Co-Pilot doesn't have an issue with these cases. I've heard that the Flymentor is more difficult to set up than the Co-Pilot and isn't that great for beginners for this reason. I can say that the Co-Pilot is very easy to set up, which is essential for new pilots.
-Reply from heli-p (34 points);
Are you heli or fixed wing? Flymentor supports CCPM and FM cp 2 doesn't.
-Reply from majik01 (7388 points);
What are you going to use it for? The co-pilot is okay for Aileron/Rudder and Elevon airplanes as well as "normal" helicopters but will not work for CCPM helicopters (T-Rex, HK helis, etc.) The Flymentor is okay for all helis(needs a lot of adjustment/tuning) but is overkill for airplanes.

When your Co Pilot is fully enabled * 100 your Ailerons work great, turn off co-pilot and only 1 aileron works. Or your elevator servo is extremely glitchy and even unresponsive at times. The missing link here is a servo buffer: ***********rcgroups****/forums/showthread.php?t=1169169

-Reply from Willard (2 points);
ok so it needs to be paired up w/ an advanced servo buffer,correct me guys if i'm wrong.then why doesn't HK sell this buffer?
-Reply from NotDeadYet (224 points);
A quick search of the CopterX 450 showed that some early version were not CCPM? Anyhoo, CCPM helicopters will generally not work with the Co-Pilot since it seeks to control pitch and roll directly. I've heard of some folks who have gotten around it by using an onboard mixer, but that's a risk you'd have to work through yourself.

Also, I've heard Rumors that the newer Co-Pilot II can handle CCPM just fine, but I have no direct experience with that.
-Reply from Shura (123 points);
Be careful! DOES NOT WORK with CCPM helicopters.
Copterx450- is CCPM heli!
-Reply from tomukas1990 (12 points);
I think HK does sell buffer. Just look around

-Reply from NotDeadYet (224 points);
Perhaps I'm not interpreting 'buffer' correctly. My understanding of a buffer is that it will help correct problems with the PWM signal. If my understanding is correct, then CCPM helicopters need channels mixed, not buffed.

Buffer might be the preferred term for mixing in another country or something though. Please forgive my missunderstanding if that is so.

FPVking (536 points)
  On the trainer plane would two gyros do the jame job for less money? Please explain.
-Reply from waterlogged (3852 points);
The co pilot is designed to keep your plane straight and level and do a very good job of it. Using two gyros will do something similar but nowhere near as well. The Gyros require correct adjustment, co pilot is ready to go. Gyros need 2 anchor points. Co Pilot needs just one.
-Reply from lobstermash (288 points);
Also gyros don't like vibration, so you have to find two spots that don't shake around too much. The advantage of gyros though is that they don't change performance over different surfaces (water, ice, tarmac, grass etc.).
-Reply from FPVking (536 points);
What about the terrain? I don't believe it? When Flying over a lake or forest or grass park what's the difference?
-Reply from lobstermash (288 points);
Different surfaces reflect different amounts of heat. As the sensor is infra red and is calibrated when you plug it in (usually on a flying field), it is possible this thing may get confused. That said, this isn't supposed to be an autopilot system, and it usually only stuffs up where there are large-ish difference in heat signature between the calibration and another surface (like a cold lake)
-Reply from lobstermash (288 points);

There are some but some of them just dissapears. Some bug I think.
-Reply from Luiz (16 points);
Not similar to 2 gyros at all. If the plane is pointing down or inverted, gyros will hold the plane there until you crash, while co-pilot will bring it back to level when you release the sticks. Works well over lakes, sea, grass, snow, etc - only get confused inside dense fog/clouds. I calibrate it over the sand and then fly over the sea/lake all the time with no issue, althought that is not ideal. It is an outstanding product for learning or relaxing flight.

Hola. Tengo un easy glider pro, con sistema osd apache y hace unas semanas instalé* el copiloto fma-copilot.

Lo ú*nico que hay problemas es a la hora de aterrizar y despegar, pues el copiloto hace los movimientos muy duros y es preferible desconectarlo, cuando lo despegas tiende a picarlo contra el suelo, porque tu quieres coger altura y cuando aterrizas tiende a subirlo para compensar el picado de aterrizaje y puede entrar en pé*rdida. Otra de las utilidades que tengo instaladas es un mó*dulo bidireccional que me pita cuando estoy lejos y se pierde la señ*al de radio, la radio es una turnigy, a parte he conectado un micro amplificador de 2 watt en la misma emisora que me da un alcance mucho mayor.

This will work on older non ccpm helis . the older raptor 50 is non ccpm. I use one on my Raptor 30 np. Non ccmp helis have a seperate servo for the pitch which is not connected directly to the swash plate. Raptor use a rocker system to change the pitch . Some older non ccpm helis had a hollow mainshaft with a wire going up the middle for the pitch. The hk 450 series are all ccpm so for them you need either a flymentor or the four channel co-pilot.
-Reply from majik01 (7388 points);
Hey Kanga - you seem like a pilot who knows your stuff. Have your tried a Multiwii board with self leveling on a CCPM heli? I have been reading through the threads but can't make heads or tails of how to make it work.
-Reply from kanga (1185 points);
No I have not but , it might be possible the software for a tricopter would be basically the same as a ccpm heli.
Finding a way to interface with the servos might be hard though .
I myself am looking at trying a Skookum 720 active flybarless in the future.
" Active means self leveling " most flybarless systems are only passsive .
-Reply from majik01 (7388 points);
Thanks kanga .. multiwii self levelling is via three or six axis accelerometers - not familiar with the FBL systems unfortunately. Indeed, the servo interphase is the challenge as pitch control has to be done via software. Looking forward to your posts.

  Just wondering how well this works for flight training (not the best pilot) with my plane (PRODUCT ID: Flyingwings-1)..........would it help to stabilise it enough to find cg, motor angle ect? I'm asking this because i've never really had it off the ground long enough to do so :)

Which would be the better option...........this or the PRODUCT ID: 9171000156. Pros/cons of both?
Would prefer not to spend too much money, but my priority is to get the plane 'flying'

yes it will help with stabilization all you have to do is let go of the sticks. you can even land with it on, just manipulate the throttle. it will not bring it back to you but will level it out. it is not an autopilot.
