Cut the red wire on the lead going to the reciever to disable the regulator and stop it from blowing up and an alternative power supply to the reciever.

That's meant to say "finally found the cheap..." But I believe the same ones you're running in your feather although I eventually managed to blow them up. Four Bricks taped to the robot, overvolting the speedos to 12v and nearly 30 slams from full power to full power in the opposite direct...

Finally found cheap chinese speed controllers with the soldering iron and ran them on 12v which they took suprisingly well surviving 10 minutes of driving until various connections fell out and 1 minute of driving into a wall without breaking. I need to have a play with servo reversing to make both ...

I've known some speedos to be able to take a bit of overvolting if you want more power for when you put smaller wheels on it. The BEC will typically be the first thing to go if you do it as it is only really designed to take about 0.5A so by disconnecting the red wire on the servo lead to the reciev...

Looking really quite snazzy although I'm worried as to how the 1mm ali and very exposed screws will hold up to a spinner...

Here is the data sheet for both chips http://elakatos.home.comcast.net/~elakatos/2006Photos/Transmit-Receive-Chip-Spec.pdf It contains circuit diagrams on how to use the chips (page 8 has the ir circuits) and a photodiode will do for the "ir reciever". http://www.silan.com.cn/english/produ...

Cheap rc toys typically use variations of the TX2B and RX2B chips that take in up to 5 switch based inputs and provide 5 on/off outputs. The nice thing about them is that they can be configured for infrared control which is a much simpler circuit that requires far fewer parts than a radio. It also a...

I thought that the potentiometer needed to be left in as a shaft for some of the gears?

Each stick has 2 axes of motion: up & down and left & right.

Each axis is a channel meaning that you can put the two channels required for drive on one stick and the weapons on the other stick with one weapon assigned to each axis/ channel.

I guess that your radio is failsafing but not centering when it does so. I'm guessing that your transmitter is for aircraft meaning that the throttle should failsafe at 0% (stick fully down). This is fine with a single direction speed controller where 0% throttle is off but not with a bidirectional ...
