I almost hate to say this but............... In the U.S there a 2 different versions of the Hitec Electron 6 rx available. Can you tell us EXACTLY which one you have? Did you tell the shop when you ordered the RX that it was going to be used with a Hitec TX? Can I assume correctly that this is a Hitec TX built for use in Europe? Not a U.S. version? You've been having so many problems I'm just grasping at straws now.
