well its rare but i have tech question
i have seen a box attached to a radio controller on rw and i was wondering how it all works .......what i want to do is have a simple on off switch on my radio that will operate a motor in the robot and turn it on and off with a flick ,as i dont want to forget to turn it off while battling as it will cook the motor ....i only have 4 channel radios i have all tied up just driving the robot
any ideas or alternatives....... ??? _________________ Photos - http://community.webshots.com/album/154092733uokpXC

Futaba 4ch radios are easily "hacked" with an on/off switch on a 5th ch, other radios I'm not to certain about other types. Its a simple soldering of 2 wires to the board inside the radio and connecting a suitable switch but you will require a new 5ch receiver. I've seen it done for rc planes to opperate retracting landing gear. I'll look up some refference material and post the links for you. _________________ Regards,

Hmm, that would be interesting for me too, as i've got the futaba 4ch skysport, and a 6ch reciever, a 5th weapon switch would be dandy!
If anyone could do it without wrecking my radio, i'd be very interested! _________________ ( •_•)

ok firstr off if u have a 4 channel and is using all channels for drive then go buy a mixer and use second stick for weopons.
thats what i have on orbit basicallym right stick drives, left operates weopon and one other is failsafe/on-off switch.
Its yall's choice but id rather do that than have someone soldering and fiddling with my radio. _________________ Andrew Welch, Team Unconventional Robotics

Eeey this old thread! Didn't want to start a new one.
I took apart my skysport this arvo to do a little mod to it (to be revealed at our next event ! ) and took time to notice that there's not one, but two pot *imputs* unused on the circuit board. Although it may be that they use the same circuit board for two radios, I do remember that Andrew has an older 6 channel skysport... I'm not really going to bother with it now, but just to bring the oppertunity to peoples attention.
Here's a pic of the radio pcb sans cover:
And a close up of the areas the pots connect to, notice the W (white) R (red) and B (black) coding on the pcb...hmm...
Enjoy, one things for sure... the skysport is one hackable radio! It even had mounts for my 5th switch XD!!! _________________ ( •_•)
