Interesting. We have been having radio issues lately. I had it down to being the Botbitz' breaking function overriding my transmitter signal and so there are delays between my fingers and the robot (visible in my videos of Mad Metal Machines last year), but it isn't consistent.

Is there such a thing as a signal booster for these radios? Obviously would prefer to avoid shelling out a chunk of cash for a whole new setup, unless someone has something going for not too crazy a sum.
