RE: Concept Fleet Biplane
My Fleet was about 26 or so pounds and with a 18-10 prop, the VT really climbed out steep and really had a time with it slowing it down.
Idled at 1,000 and maxed out at near 8,000. Scarry for me but the valves didn't float. If I went back to the 20-10 I could reduce the top end but wow! what a motor.
I had all my settings letter perfect but since I sent it off for major overhaul, I still fiddled with them. At idle, it smoked greatly and would load up and lose a cylinder. Any leaning gave me fits resetting the idle stop.
All in all, still a worthy engine.
