Aux help for scale heli

[Pj1969]

Im just in the process of building a Trex 600 Airwolf and although im ok with the set up of the Brain, i want to put the nav lights and retracts onto separate switches, so i can flick them on/off from my Dx9. I'm using a talon 90 esc with built in BEC, so i was going to take the power from that, can anyone tell me if it is possible to use the brain and the switches for what i need? i understand that there is 1 AUX chn (chn 2), so i guess to choose between lights and gear for that, but what to put the other on?
This is what is on the brain
ch 4/5/6/bind
ch 3/s rec
ch 2/aux
ch 1 thr
servo 1
servo 2
servo 3
servo 4/tail
SYS I/O

The nav lights (6v) have a control box with red/blk wire only. The servo has usual 3 wire lead (brwn/blk/yel so what would be the best way to do it????
I will be running all this on a 6s 5000 lipo, so im sure there is enough power for it all, didnt really want to add a separate lipo to run things on.

Could you not just run those functions through the reciever?

If your lights only have a red & black wire then it doesn't sound like they come with any way to switch them on and off remotely, you would need to buy something else to allow that.

And if that's the case, put the retracts on a spare channel, and just have the lights permanently powered.

If you do want the lights on a switch, if you're using a receiver there may be another channel you can use there, but you would need to buy some kind of remote switch, and I'd also double check the power draw. It's likely to be low, but I always check if I'm drawing power for something non standard out of a receiver or FBL unit.

What about using something like this Multi-function Stepping Remote Switch 1 Servo Signal Input RCD3003

Cheers Marty, that looks like the way forward??? Out of stock tho, I'm not using a receiver, only the brain. I'll give them a call

The only way i could get the retracts to work on my airwolf with a vbar fitted was to put a reciever before the vbar and use the aux2 channel of the reciever and assign
it to the mix switch on my dx8, and i run the retracts off a separate 2s lipo just in case the servo jams and draws lots of power from the main
lipo, works a treat.

Ah- not familiar with the Brain. There's this jobbie as well - in stock! RECEIVER CONTROL SWITCH, Robotbirds

Good luck Marty

Thanks for help guys, FL didn't really have a clue, well the dippy guy I spoke to didn't. May just try using the AUX in the brain to run the retracts servo and rig up some sort of small permanent pwr for lights with just a simple on/off switch.

Hi mate on my scale Cobra I run a hobby king BEC off the main battery this runs my Nav lights ,the aux on the brain is not used so you should be able to run retracts off this , if your using a full size receiver use a spare channels on this to run retracts and nav lights hobby king does a switch that works off the receiver then lights plug in to this , if you have the DX9 transmitter you can use a set up to slow the servos down to make it look more real

well it's done!!!! I had an old align reg lying in the bottom of my box, so I've put the nav lights on that with a 3s lipo and switch on the side of frame, neat little job. The servo was simple enough, I just plugged the landing gear servo into the Aux Chanel on the brain and assigned switch F to it in my dx9 and it works a treat. Landing gear up and down slowly with a flick of a switch.
Thanks for all the tips and input, now just a few finishing touches and I can have a go at setting the 600 up to fly before I take it apart to fit the Airwolf.
