Well, I was only able to get about 3 tanks through the buggy and 1 tank through the truggy because of the weather. I made the voltage regulators and installed. Packed up, went home, un-packed and the rx's still worked!!
So, I hope this solves the problem. Had to mount the caps to the transponder screw hole. When I get the battery forward mod, I'll be able to put them in the battery box.
I'll keep my fingers crossed and see if the rx's survive the next weekend!
Thanks All
Brian
