Hi Rob yes tried it done about everything different motors new capacitors new boards different transmiter this problem only started after fitting schurzen .so if the schurzen is causing the drop in range must be either stopping signal which it cant be because it works or it is not letting R.F. disipate if you like the schurzen is turning into a fariday cage .so the only way I can see to stop this is make a fariday cage around the drive motors ,then the R.F. will be contained and shouldnt interfere with radio. I cant think of anything else really need a radio ham who knows alot about what causes a reduced signal strength .


best regards pete
