O.k. guys,I know I know I'm new at this but I recently completed my 1/4 scale Cub project.Installed a Zenoah G26 as power. Problem is she is glitching on all servos when engine RPM is increased. Rudder seemed to be the worst of them all so I changed the servo, also at the same time went ahead and changed the Y harness and installed a new receiver, rerouted the antena, still no good. Also tried, in round 2, throttle servo and attached my ignition ground to a different location. Still no good. These engines come pre equiped for RC applications don't they ? You think it could be the ignition, sparkplug, plug wire ? Any ideas are appreciated....I've ran out..[]

Thanks,Ray
