Hey Newee ... I've got the same exact model ... but it is still in its box. Since you are building yours first - I can pick up your tips (he, he). , Biggest showstopper for me was the tail section and I was thinking of beefing up the tail like you did or going for a T-tail redesign. Reason is landing ... with the tail section as it stands ... I get visions of concern when the model plows through grass and short brush - ouch. Another is the tail servos ... having long control rods can cause flex .. can be fixed but attaching the servo to the tail itself means I only need to run four wires through the tail boom ... Two signal, one power and one ground. The T-tail would be detachable (like most of my large birds...) and would be held in place with circular clamps or screws through the boom. For the motor/prop, I have been experimenting with folding props - don't know if that will work but it looks cool. For the camera, I was actually thinking of putting a BL gimbal on the nose of the airplane - I already experimented with putting a BLG upside down ... surprisingly, it still works. Stopping here for the moment ...
If one was to take this up as is I could see the tail supports that are OD to boom would be torn off in just a couple of landings around here. So it was either a skag from nose to tip of boom or conventional landing gear in the tail dragger configuration. I may order another one and build it into a tricycle configuration as I already have all the parts and peices, including a few "Eflight" 9gram servo's from a "Apprentice" that had a fatal wing spare fail at about two hundred feet. There wasnt much left,,,,he he. Have you ever built a twin tail? I havent and want to try one because of the athority the rudder and elevator have with all that control surface. Ever since I found I could configure the MWFC to an airplane I am serious about giving it a whirl in the Cessna 180 but start out as just flight control for level flying and then tweak it alittle at a time to see if it can do most of what the Arkbird AP can do. The APM can utilise a "GEO Fence" kinda like what Gordo was talking about on his multirotor. That fence being gone out of bounds activates the RTH and auto land feature in the sketch.
Interesting story for the Apprentice ... the models that have disintegrated in my hands were a 64mm EDF EPS Kyosho A6 ... I was able to fly it before ... but in cold weather, the wings do not have a lot of lift and it .. well RTE'd ... also hit the deck with another GWS EPS E-Starter high wing ... smashed it so bad not even hot glue could put humpty dumpty together. Which is why I started looking at EPO and EPP - pricier but could survive RTE's that would have written off an EPS. I digress .. I have not tried twin booms before .. I had played around with the MWC airplane "frame" before ... this is actually what I used for the Multiwii self balancing robot .. it was the aileron servo output ... and worked. Sometimes my own curiosity leads me to very strange places.
Hi there. Im trying to make this board working, but i cant get any reaction from receiver in gui. receiver is properly binded with turnigy 9x, also on other multiwi nanowii is everything work fine.
another thing is, that there is no power from A8 pins. (should be 5v right? )
i had to power up receiver from serial 2 where is 5v and ground.
every help will be appreciated.
Tell us a story of what MWC version loaded, what receiver you are using and how you connected it to the board. Powering up for GUI work via USB works okay. So how are you powering your board such that you don't get power on A8? - Lipo via BEC or USB ? Don't suggest having both connected at the same time though ...
yo thanks for reply :) its 2,3 and i also try 2,2 with same results... reciever is turnigy, that came with transmiter 9X. (9ch). everithing in gui works fine also gps, but when i move with sticks on transmitter nothing hapen in GUI, (im powering board with usb and lipo via BEC together)
Check you config.h if the cppm line is uncommented ... if you have the TGY 9x, you need to use the default regular receiver - comment the ppm lines back. Check also polarity ... outer ground, center power and inner signal. You should now be able to arm ... if not .. not all it lost.
Maj, Mooch finally pulled the trigger on a FC. Took Mooch's advice after doing some homework. Really had my heart set on Arkbird w/OSD built in here at HK $160.00 here in US. That other place had the APM 2.5.6 Combo with everything already soldered togeather including the Neo-6 with attached external compass and many other goodies with programming possibilities that include auto take off and RTH and auto land functions. Also Maj, I did a bit more research into our favorite MWFC! and it will do airplanes as well. You were right about alittle tricky though as the "Horizon" mode we all love and use, would have to be only used by the APM in level mode, but doable. I went ahead and buaght it becuase of the money already wrapped up in this fixed wing project. I have some still pics and will throw up here from piecing togeather. Been slow as health keeps pulling me backwards at times, but am putting togeather with patience and forthought. Pretty much a given to have to employ LRS Coms for this one. But learning curve to load updated software to Rx and Tx moduels sounds alittle confusing. Am adding landing gear and steerable tailwheel to this monster, and modified motor mount to attach 3550/1450Kv motor and 11X7 power screw and HQ prop selections. Pic's will follow. Still trying to work out acceptable place to mount 50amp airplane ESC to outside of plane to get proper cooling.
I hope you are monitoring teach,,,as I have a brain burner. If you have knowledge of this or know how I would find an answer,,,,I have run into bad feedback on weather this Tx moduel will even work with T9x or the T9xR,,9171000284-0 - OrangeRX Open LRS 433MHz Transmitter 1W. Something about a 6 volt programming pin in the plug into the Tx moduel where it plugs into the radio? Been burning brand new moduels and radio's up in the process? Do you know what they are talking about Maj? I thought these moduels were plug and play. Must have long range as you can get out of range on the stock T9x Tx moduel if you are not watching close. Had it happen to my Cessna 180 when I flew it to the water tower here near town and was in a level flight, it started to not follow all commands from radio and a breeze blew it back heading towards town and just caught enough signal strength for a moment to put into a dive heading towards me and that solved its self getting closer, but that was a but pucker moment I'll have you know,,,lol
Newey, You are really going to like ArduCopter. Is the neo-6 you got the big one? If it is, you will have the same one I have on the hawk. GPS hold locks in place like it's hanging on a string. Same with ALT too.
Newey, there is an electronics place called digikey that sell every heat sink know to man, and in small quantities too. I'm about to get some for my 650's ESCs. If you are worried about the heat, you might check them out. I also plan to put a temp sensor on one as well.
If you are worrying about the OpenLRS and burning radios, I think it's the other way around ... OpenLRS modules having problems with 5V from FTDI cards. But having said that, it would only be during firmware upgrade - something you do not need to do if you have your units already working. But here's a thought ... the 100mw (vs 1000mw) OpenLRS units can go beyond LOS (say one mile). You would only need a 1W unit for super duper range ... at those distances, the video Tx, telemetry and control equipment costs increases exponentially ... not to mention the risk of losing your investment. Build using your existing Tx/Rx and look at long range radio control when your bird is flying properly as the radio is the easy part - the flight controller will give more than enough challenges.
I think I agree Maj, LRS later. I have done so much with this kit already, but I knew I was going to before I baught it, so no complaints there. I have built in 50% and 100% flaps, forward mounted servos for CG, reinforced all of the rudder assembly as it was shamelessly under built for a plane of this size, used upgraded horns everywhere that are adjustable on wing, Modified motor mount to acomadate the 35mm/1450 kv choice of motors and a inch bigger three bladed prop. I like the truck appeal this thing has, but the flying will tell all. Going to mock up and weight all that I intend to mount to see where the CG will be fully loaded. Going to run down and do a quick vid, and I like the idea of air vents Maj and can fab them to be directional front to back for cooling. Have to figure how to level the FC with the CG and side to side. Still have some learning there too,,,fun fun.
Newee ... you'll find a properly provisioned FPV airplane can get heavy fast. Plan to have an assistant with you when you make your flying tests to launch and spot for you ... a strong wind can yank it off your hands and ruin your whole flying day ...
Ive been working on my quad for a while and it still wont work i am using multiwii 2.3 (one of the premaid version's off this website) the problem is the quad wont arm i have set up all the rates the quad goes into the mode where it is ready to arm -red and yellow led's flashing it does that for five seconds and then goes back to just the blue led flashing with the two above and below it solid . so i wonder if anyone can help
I would suggest plugging each ESC directly into the throttle channel of your receiver and calibrating each separately. If you've already done that or once you do it and if it doesn't work try re-flashing the firmware on it. Sometimes that can help. Also check your minimum throttle setting. Sometimes your radio will output throttle ppm that is outside of the bounds of multiwii to pickup. I had a similar issue for awhile.
Also make sure you do all the calibration (Acc, level, and mag) in the multiwiiconf.
Marco to add to what Michel already said, with the end points that are visable in the GUI. Have you calibrated your radio,,,and what Tx do you have? I have run into this problem alot and the quick answer to check if this is the issue,,,adjust the trim to the yaw to starboard (right) side and adjust the throttle trim a bit forward one click at a time on either trim untill you are able to arm with stick inputs. A way to see if quad is able to arm is assign arming to one of your aux switchs and then arm with that switch. If it arms you know you have to go into radio's end points and fix adjustments there. Hope this helps! Fly safe.
Marco ... follow Mike's advice ... but my guess is that the firmware you uploaded still has the ppm line uncommented. If you are using a regular receiver, that will not work. Just a suggestion, download the official version (2.3 will be okay) for now and uncomment frame and sensor for now to see if you can arm. If you cannot, read the doc in Files (what to do if your board does not arm) ... hopefully you can arm. When you can fly - you now know the gottchas and move to MWC 2.3 Nav for some serious fun. Come back if GPS gives you a heart burn.
Thanks for all the advice i shall try what you have all said tomorrow and come back if i have any problems, mike i am using a ornage rx dsmx 6 channel and have all the thrrows set between 1000 and 2000 could you recommend mincommand and minthrottle values.also is there a specific version of the premades on this website that you would recommend as being the most newbie friendly? thanks again, marco.
one last thing even when i was trying to arm through the stick function it still wouldnt arm it would recognise it was trying to arm but when i go into the status part on the gui the baro acc and the rest were lit up however not the arm. it goes through the stage of saying it can arm but then stops i dont know if that helps with the diagnoses at all also i have had it arming but then chagend something, it stopped working , changed it back but it still didnt work so i am having a really hard time :( its as if i win the lottery then walk off a cliff
That's it Marco - comment that back .. but again I suggest using the official 2.3 until you get to fly properly and move to 2.3 Nav. I don't use the DSMX receivers - but they should be okay. Your endpoints can be adjusted if your board does not arm properly.
Great unit, with all the features you need for your MC. And the price is awsome, so normally, you cannot make a mistke on buying this unit.If you buy this features in europe, you will pay 3 times as much or more. For the HK price, you get at least the gps module ( sometimes ) but not incluiding the board, wich has a big and powerfull processor also. So another time, where HK makes our hobby affordable. This is what the MC-Flyers need to upgrade their machines.

Received the board today from HobbyKing .
After reading about all the broken Micro USB connectors on other FC like the Crius AIOP , I had a good look at the USB connector BEFORE connecting anything.
The micro USB connector is soldered to the board at the rear corners and also has 2 tabs half way down the sides.
Close inspection reveals that it does NOT have a lot of solder to hold it in place and YES it is likely to break off without some extra solder.
The side tabs do not appear to have been well soldered, my guess, surface mount automated soldering has not applied sufficient heat to get the solder flowing well around the tabs which are part of the larger metal connector shell, using a fine tipped soldering iron, care is required specially on the side near the pin headers, re soldered the metal tabs and also the rear corners of the connector, I don't think it will come off now.
Do keep in mind that is a very small connector and the cable can be used to apply sufficient leverage to rip it clean off the board, no amount of extra solder will prevent that, so be real careful not to apply sideways forces to the cable when plugged into the board.
The quality of the board, the soldering of all the other components, I can't fault it, all looks excellent.
Lots of information now in the files tab for the product at HobbyKing.
I connected the GPS to Serial 2, and the flashing LED
