Hi,

Mike the engine is mounted to the airframe using three bolts (red arrows) which are parallel to the crankshaft axis. It also has four tapped mounting holes (blue arrows) on the bottom which we are using for a speedboat.



The pipe is what gives the engine so much punch....without it I cannot get away with using low compression and somewhat high timing. Planning to use aluminum for the final pipe on the airplane.

Cutting off half the crank and some of the cyl. blk. is a good idea as you said.

After reading some posts here I am thinking if it would be worthwhile to try out a glow (gas+methanol) conversion for this engine. What do you guys think?
