Hey G, i had exactly that problem with my car at oz. Rang the very helpful peeps at horizon and they took the set back to check it out for me, no probs since. They said that most don't run a cap on the micro reciever?
I also put the aerial wire as long as poss, protruding through the shell and tough wood, all is well. I also changed the speedo just in case.
Good luck mate.
Hey i never did get those drill bits off you, nevermind, next time
