RE: At a certain engine RPM my radio gear goes nuts ? Troubleshoot..
I have a Voltwatch inside and the battery was good. I tried with another battery pack as well with exact same results. I agree my radio is a bit old but I tought radios lasted a while.. I has different brand servos so I tought maybe some incompatibility issue but now I changed all the servos to Futaba S3003, S3004 and old FP-S148.
