So.. that Leopard 1 up above. That is the 35rctank electronic system. I dont think that GSU will work with another board like the Clark. And it is not an IR capable system so if your looking for just sound and movement, that would be the hot ticket...

So we are back to the gyro system. I am looking at the Hobbyking RX3s. Its cheap but looks like it might do something. And, it can be switched on and off...
