Wireless Buddy Box System 8CH (Dual RX Controller)
The Dual Reciever Unit is a wireless buddy box interface that can be used in a variety of ways and even allows 2 different makes of Transmitter to be used in a Buddy configuration!
This has amazing advantages over the traditional system that has always required the master and slave transmitter to be the same make and on top of that, you have to be connected to each other via an easy to pop out short cable and in turn, the cable ends have to match......the Dual Reciever Controller does away with all of that.
The Unit inter-connects 2 x 8 channel Recievers that do not have to be the same make and this in turn allows JR Servo configuration to work with Futaba servo configuration and so on. As well as pilot training, this unit can allow 2 x TX to control one model, this has many potential applications, for instance, for safe FPV flying, this will allow your observer to take over the flight at the flick of a switch if need be. The unit is small and light as well as simple and fast to set up and isnt much more expensive than many buddy leads!
I just asked the customer service and they said that there is no ETA for this item but it would usually arrive within 30 days. This means nothing in my opinion so I will just wait.
you can of course if urgent buy two of the 4 channel version and join together.
using y leads to join battery supply to both, also y lead to join signal to both from master tx.
slight weight increase but not enough to worry about
THATS WHY ITS ON BACKORDER, everyone wants them.
At the time I wrote they were available, and just as easy to put two together.or go without.
It depends how urgent you needed to fly buddy wise.
At least it solved the problem
Hi everyone, I want to buddy a cheap radio to a better 6CH FlySky but the cheaper one doesn't have a trainer port so this is my only option. I'm just quite worried about weight as the cables will add a lot, is there a way if hooking up the receivers without all those cables? Thanks in advance!
search "3cm jr" on HK there is 10x 3 cm male male cables you can just use them, you only need one for every 3 signal wires from rx to wireless buddy box.. as all and - are common.. if require more info feel free to ask
make that search "3cm servo" ... more to add to before... you will require one lead for lets say channel one that is connected -, ,S (signal) then one lead (side on) will do channels S2, S3, S4 (signal only) the third lead will do S5, S6, S7... (signal only) and S8 (switch) could be another -, ,S if you like for safety.. id show ya my set up but erm... back bloody orders....
i have a question, rule in nz state i need dual rx (failsafe)with my 210cc 42% extra, im using FrSky telm rx's, and 9c fut tx, can i use "dual rec" for that purpose? ??
It sounds like to use this system on a 5 channel plane you have to use the controller, two receivers, and ten servo extensions. Try to find room for that in a foam trainer plane. Not to mention the major rewiring you have to do to the students plane to set it up. On a typical training night we can have 5 or more students. If I would have known this I would have never recommended the Turnigy radio for new pilots. A buddy cable works much better.
You are right, Phillip* except with this system you do not have to have both radios working in the same mode, something you can't do with a buddy cable. I have one set up to teach a student who can only fly mode 2* I can only fly mode 1. Absolutely no issues!
The extensions are only required between the receivers and the dual controller - normally short ones. I am flying a small J3 and have no problems packing in this stuff.
The buddy cable works very well and should be used regardless whenever a new student is flying. However changing radios 5 times a night could make for some interesting trim problems as radios of the same brand are not always identical in settings.
Channels are assigned letters. As long as the same function coincides with the same input and output letter, it works.
Master is 8 channels, the slave is 7 channels. The 8th channel is the switch. I use the gear switch as the 8th channel. Works very well without any lag at all. Brilliant.
How long to wait, before item change state from backorder?
I'm waiting for him since November and nothing yet.
I can't believe that "Stock updated frequently"(((
Same here. Because of this single little (but very nice) thingy, my whole Order with a complete X-Quad and much more is hanging - HK - do you hear me?? Jump this Manufacturer on his toes!!!
yes its 7ch outputs that the trainer can use and the 8th is for the master control as a signal wire.For example when channel switch is flicked, the control is switched over to master/trainer
It apears that you could use a 2.4 transmitter for the master and a 72 mhz for the slave with this setup. If I am understanding it right once you flip the switch the slave system is in control of the slave receiver. Flip the swith again and the master is in control of the master reciever. So you can use any transmitter with any other transmitter. You must however have two recievers in the plane, one for each transmitter.
Is this correct? So you have two recievers hooked to the servos, and by fliping the trainer switch on the master transmitter you decide which transmitter controls the plane. So as long a the reciever for the selected transmitter works togatherwith its receiver everything will work prefectly. All you are doing is selecting which transmitter is in control* is that a true statement?
Listen up. A lot of the confusion here is because people don't realize that there are no electronics or switches inside this thing. It just wires two receivers into one output to the servos. You could make the same thing with a bunch of Y connectors. So to switch between pilots, you have to tell the other person to stop flying (to pull on their trainer switch and hold it there.) The one who ISN'T holding their trainer switch against the spring pressure is the one that's flying. The ONLY purpose of this is to allow two fliers with different brands of TX & RX to fly. The simplest solution is to buy a cheap buddy box and trainer cable that works with your TX, and let your buddy fly the buddy box. Much less hassle.
Sorry, but what you are saying is wrong. This module is controlled by one channel of the master and with that one channel you can switch which of the two connected receivers controls the servos. Furthermore, if there are unused channels on the student side, then the master channels are used.
This controller works by switching relays when the master activates their "master" switch. When the master switch is on, only the master's receiver is controlling the plane. When the master switch is off, the student's receiver is in control of the plane.
also the benefit of using the wireless vs wired buddy box system is that the trainer and trainee don't have to stand right next too each other.
For example when i was learning too fly fpv i was able too stay in the shade to see my screen while my buddy stood next to the landing strip and kept eyes on the aircraft taking it when ever need be.
Also if you want to use any autopilot or flight stabilization systems you can wire the aircraft to bypass those systems in case you want instant full control of the aircraft.
yep i think they started stocking those leads just after I bought mine. I got around it by cutting servo extension leads in half and re-joining the male ends. Bit of messing around but works great.
Hi All, I am using a Spectrum DSX9 transmitter as the master system, but I can not figure out which channel or what mixing I need to put in to the radio so that the trainer switch activates this unit. Any suggestions or information would be appreciated
I'm don't think you can use the trainer switch because that switch doesn't do anything at your receiver, it is meant to disable the other person's transmitter if you were hooked in via a trainer cord. You need to use a switch that activates something at your receiver and then use that receiver port as the "ctr" on this switch, any switch which activates something at your receiver would be fine. For instance using the switch that would raise or lower your landing gear would work fine (provided
This is all dependent on your Tx i use and aurora 9 and i am able to assign my trainer switch to any channel i want. All switches and sliders are free game on my system. i would just recommend reading the manual for your TX.
Plugged mine in after being stored for some time. Does not seem to work. Using two 8 channel recievers (pre bound and tested) and 5v flight pack. It looks pretty simple but I hope someone has any ideas? It makes a high pitched squeel at times. Plugged servos into receivers again and they seem ok. Polarity of leads ok. Using ch 5 of my 9x as CTL. I'm just hoping its not a dud.
whiskey29, no neither seem to pass information to the servos, is it meant to get warm?! Felt one side definitely warming up :( Retested the RX's and servos and they still work.
WOAH! Looking at the HK picture above, From memory, My master input for "A" is not in the same position as this one! Maybe the packaging is on upside down? I cant check now but in 2 days I will check. Lets hope.
mine exactly like hk label.
You might want to test one servo on one channel first. Try to see if it works with master, then rather than mixing, just turn of the master and test for the slave
Just tried with the unit "upside down" and one rx works but does not switch over. My Master input does not have the letter A with pins. That is, only 7 channels available to plug into. Suggests to me that the outer cover is upside down, anyone else get this senario?
So am I righ in thinking that this will allow a Mode 2 trainer to buddybox for a Mode 1 learner? It's just a matter making sure the leads are all hooked up to the correct pins.
If you are going to be a great part in the program, then you have also the connecting cable between recipients and the Buddybox offer beipacken or directly. Although I can solder them but not everyone can do that. So please Servokabel plug with double-sided 10cm long into the program to pick up.
True, Hotzenplotz. Easiest way to do it: Buy some servo extensions here (quite inexpensive) and cut of one end. Then crimp the correct plug instead of soldering.
How can the cable manufacture is already clear to me. It is important to me only if you have a product offering for this reason you should also offer the Zubehoe. It certainly giegt many modellers who do not trust the Krimpen or soldering.
You could actually have 1 Instructor and 3 Students using this unit. I'll try to explain... The instructor has his TX set up so that Ch7 switches between the 2 RX's connected to the 'Dual Controller' then at the same time his radio could use the normal buddy lead and switch to give control to student #1 (still using RX#1), he could also flip Ch7 to give control to student #2 radio using RX#2), from there student #2 could pull his buddy switch to give control to student #3 (using RX#2). Hard to explain in text, a diagram would be better. Think about it, I'm sure it would work. I have one of these units and might test this theory one day. -B!LL!
Sir it is 8 channel. This is how they work. The master uses a channel to switch for Trainer to Student. So yes the Student has only 7 channel available. But this is how it is done.
You connect one end to the servos, on the other end you can connect two receivers. Sadly you will have to make your own wires/plugs for this.
The master has one additional channel which should be operated by a switch on the master transmitter. With this one you switch between master and slave (trainer and student).
It is also possible to just have one or two channels (elevator and aileron for example) connected to the slave side. If this is the case, then the master will control all open channel
I honestly don't know but if it can't the just connect the receiver that is normaly used as the slave to the master side, or better still just plug the servo wires straight into the receiver you want to fly with. 1 minute and you're all done ready to fly.
Thank you for the answer, it is correct what you write, but maybe there is a difference if the switch on the master is used closed or opened to choose the slave. I do not (yet) have this Buddy Box, but I think it is worth trying !!
I also think there is a simple solution: program the slave TX that way, that it can also give the switch - pulse. So when the master isn't there, disconnect HIS pulse wire, and plug in the pulse wire of the slave, so the slave can give himself permission to fly!
That should work I think. I still think if you sometimes want to fly it on your own the best thing would be to plug all servo wires directly into the receiver your going to be flying with. Less chance of anything failing.
Of course this is right, but the way I propose has the advantage that I only have to switch ONE connection!! And all other connections remain in place for the next flight with the master present.
Anyone know if the /= rails are on a bus? If so, then save yourselves some wires and weight and just use single female/female wires to connect the signal wires only. (Get them in bulk cheap on ****)
Thanks heaps elchan : ) I was worried about all that extra weight, not to mention the hassle of making all those cables up. You just cut my work down by nearly 2/3rds and saved a lot of weight! Why the heck didn't I think of that myself.
Could this be used with two 6-channel radios? From what I can see in the manual, I would think I could use 5 channels (A, B, C, D, E only), then use the control channel for the master rx. Channels F and G would be unused.
Yes, that should work fine. You should be able to use up to 7 control channels, with channel 8 being only used on the master Tx to switch from master to slave.
Don't forget you'll need quite a collection of double-ended cables to connect your Rx's to this gizmo.
Hi Guys! So where is this mystery "switch" situated. Is it actually inside this connector? as some one said in an earlier comment, that there is not a single component fitted inside this device. Just bare printed circuit boards, commoning up all of the associated pins. True or false? I have made up 6 sets of "Y" cables in readiness. So how would I go about incorporating this mystery swich using this method of connecting?
Yes - this is quite simple. You'd just need to arrange the cables between Rx's and the buddy box to suit.
Your ESC and servos will always be plugged into the buddy box. You simply have to connect the "throttle" channel from both Rx's into the same channel on the buddy box. Then do the same for ailerons and so on.
As far as I can see, the biggest problem with this product would be the massive bundle of wires in your model.
I don't understand chinglish and the explanations in the file section are not convincing. Which one is the pin that allows the Master/student switch ? Unclear in the text description and on the picture, where pins have awkward labels...
GessWho, this should solve your problem www.link (10CM Male to Male Servo Lead (JR) 26AWG (10pcs/set)) Product ID: 258000011
Thanks !
A trainer cable has some advantages over this though. There's only one receiver, you only program one transmitter and set the other to neutral, if you're flying a complex plane you only need one programmable transmitter, the slave TX can use all the mixes of the master TX, and you avoid the expense of buying two complex transmitter. Of course if you're just doing basic 4 channel flying, most of this is moot.
I just sold my FM and older AM systems because it was too much trouble to interface them with the 9X, even when I had the correct cable. This would have let me keep my AM system as a buddy box AND use both systems to back each other up in case a transmitter loses signal because I dropped it in the toilet while flying.
u dont need anything but y leads put socket on servo wire and 1 plug into each recv one will have override priority so use this 1 for trainer $3.00 all done ps i have been doing this for a year
Beladog, KaosKane didn't fully explain what he's doing until farther down in the comments. He has to tell the other flier to stop using their transmitter so he can fly, and vice-versa.
I think what this is really for is for two people flying FPV or training, each with a different brand TX. (One using video glasses, and the other a safety pilot, for FPV.)
G'Day sloperdude Thanks i only wrote the two replies because the orig post had been removed. but as the orig post is now visible i regret writing the short reply version, leaving out the details u mention *}
How does this module know which receiver to allow control of the servo? Or does it average the signal between the two? Or do you need to turn off one of the transmitters when you want to control the plane using the other transmitter? I just don't understand how this device works. Thanks.

If you look at the illustrations, the Master Rx has 8 connectors with one labelled CTRL and the slave has only 7. One of the 8 Outputs is labelled Batt. My guess is a that one channel on the Master is used to switch from Master to Slave. There are 7 controlling channels left to use.
If you want the instructor to keep control of a particular channel make a "Y" fem-fem-fem and instructor's RX can control student throttle (or whatever) in addition to their own.
If you want more than 6 channels, use two of these devices with your many channel RXs.
Génial! pratique pour faire de l'écolage. un élève peux arriver au club avec son propre matériel et effectué son premier vol malgré l'incompatibilité du matériel Maître-élève. Passage du maître à l'élève en soucis. Idéal pour les groupements.
This is just what I have been looking for, now I can train a few of my freinds to fly. Too bad it didnt come with the wires needed to hook the receivers up. Cant wait to get it all hooked up to try it out.

Get hold of a couple of packets of whatever matches your servo/rx requirments like say servo extension cable pack AM2001-45x10 and some 2mm shrink and with a few hours wor you can have a buddy set up with extended cable connectors soldered and shrinked on and you can just plug in and out as you need or swap Rx's as wanted
Great must have system for the money. Really this is awesome to help someone learning to fly or for fpv or any robotics system where you want to be able to take over control whenever needed. Comes with some basic instructions on how to hook everything up. Fairly simple with master and slave set of channels that match the end channels. On the master you have an extra channel to control the one that is used for actual control. It does only give you 7 channels though, not the 8 that is listed in specs. Read the manual in the files section for a better view on how this one works.

Thats awesome, I was looking for one of these about 12 months ago and couldn't find one, so I made one myself. All you needed was Logic AND gates. But I think I need to buy one of these still cos it looks much nicer than mine.
