Per our phone call, set 'er rich and let it unload in the air.....!
Okay, it's not exactly the lightest engine around and you have to adopt a carb to it (and a muffler if you can still hear after years of hot 1/2A's), but where else can a guy get a throttled 1/2A with a muffler that belts out that kind of #'s? As for the weight, I'll find somewhere else in the airplane to make it up if Ihave to.
Even at $100++ Ithink these are a bargain. A guy would have less in these after adding a carb and muffler than a Fora or whatnot with a fixed venturi and no muffler.
Iwas talking with GKamysz last night about changing the liner height to detune these a bit for better performance on 'regular' props, he seemed to think the idea merited experimentation. Also piqued his interest at the idea of a diesel conversion, but that's more his bag than mine-Ican't discuss it with any authority. Greg?
