Cowl mount distance
With the 3W 100 the distance from the fiewall to front of the Cowling came out at 7 3/8" on mine. CG 1/2" behind wing tube. Awsome flight performance. Hovers just above an Idle, and the easiest plane I have ever torque rolled. Spins the 27X10 at 8,000rpm Hey Mikey I like it I like it!!!!
