Hello all! This is flat top's old man. Like he said, I am using a Hitec Eclipse radio with a RCD 3500 rx 3600 Mah bat on rx, 700mah on ignition. The only part of the ignition system in airframe is battery and switch which are 8" away from the receiver. We have bypassed servos and all switches. As of last try, battery and ignition hooked direct on engine box 17" away from receiver. This didn't resolve the problem. The wire and boot on this eis is just like the one you would see on your car. I can't find any loose bolts? Could the eis have a crack or anything like that? The push rods are all nyrod and ball links. I will try to get some pics on in the next few days.

Thanks to all of you that have posted! Hopefully we will get this bird to fly...
