Recommend R/C Controller and Securing Channel Header Pins on Rage Bridge

So I have 3 questions:

1) I was wondering the best way of securing wires onto the Channel Input headers on a rage bridge, my receiver has individual pins, so at the moment i'm using GPIO leads.

2)A recommended way of splitting receiver channels when running two rage bridge controllers, at the moment i've got it working byusing a breadboard :proud:, not exactly a robust solution lol. Is there such thing a channel splitter?

3) A recommend R/C controller for bots, as the one i'm using is not ideal as the rudder controller (basically the right thumb stick) doesn't bounce back which is a pain when you're trying to stop the bot. All the controllers i find are for Planes and i just want one which has two thumb sticks that bounce back.

1) Hot-melt glue - its ugly AF but works. Most builders use 3 wire RC cables with a single connector at each end.

2) You can usually just solder up a Y cable but a more elegant solution is to slave two channels together in the transmitter's programming and use separate cables on the receiver.

3) Why do you need two spring loaded sticks? The Rage has built-in channel mixing so you can use just one stick without any transmitter programming for steering and throttle. You can also look at a 'wheel' radio for RC cars, which has a trigger for the throttle channel and a sprung-loaded wheel for steering
