Ok Guys..here we go.... I have A GP Patty Wagstaff Extra with a BME 50 and for months I had RF problems and like most I listened to all of the Wacky Ideas on fixing the problem. Here is the fix.....call CH Ignition and ask the guys to explain about the Bosch resistor plug cap. They will tell you that this WILL fix your problem. It made my BME run with outstanding results and increased my range by 150%!! I dont understand why the bosch cap will not work on a 10MM plug? Can someone explain that to me? When I compare both plugs, one out of my BME 50 which is a NGK BPMR6F and the one out of my Zenoah which is a Champion RZ7C they both have a 15MM hex installation shoulder and are both pretty close in length...why wont the Bosch cap work???????? Any explanations? If you install a PCM receiver in your model with RF issues all you are heading for is a PCM lockout and a out of control model!!! Seen it many times. Some times it works for months and sometimes it works for a few flights. Just remember DUAL CONVERSION FM is your best bet. No one has given me a GOOD reason to run PCM. Any Takers???? Fail safe you say??? Well give me a scenario that fail safe will ALWAYS benefit you? The only fail safe mode would be throttle shutdown. But a PCM lockout is very scary with a 10 to 50LB model! This is an awesome fourm keep it up!!!!
