Have a two or three year old Fuji BT-32 and all of the sudden am getting radio interference. Cannot get more than 30 FEET on radio range check with engine running. Have tried two different recievers on two differeft freq's. Changed plug. Checked for any loose metal to metal chatter, done everything I can think of except change ignition module. Not much info from Fuji, except to tell me to do everything I have already done. Anyone have a suggestion other than get a "good" engine? []
