Thank you, Thats the BME 50 with a stock muffler. I really wanted to go with the cannister but I think I will save up for a spectrum system instead.
I'm having a very bad case of RF blues. With my engine running I can't walk farther than 10 feet before the servos go crazy. I check over a lot of things while at the field in an effort to get the maiden in ,ut no luck so far. I thought the problem might be with the servos for the choke and throttle being up front, but when I disconnnect them from the reciever and pull the wires away the effect was the same.

While reading up in the gas engine forum on RF problems, I learned that if the interference happens slightly less than the engine off distance (35-50% of engine off), that it might be RFI related and if it's much worse than that it might be vibration related. Either way I'm trying to narrow it down. The weird thing is this complete system, engine and all came out of my WH bipe which I had just recently flew 2 weeks ago with absolutely no issues. In going over the CH ignition unit I noticed the hall effect sensor lead looked weird. I moved it a little and it broke away from the bracket. Terry from CH is sending me a new one. When it arrives and I'll be able to continue trobleshooting the problems.

That small metal box you see on the top part of the engine is the CH Ignit.
