Steve,

Thanks for the reply. Sorry if I struck a nerve.... The reason I was asking was that some time ago, Henry told me that the 23 would have the ability to rotate the cylinder thusly placing the muffler to the rear of the engine. This would have made a narrow profile for a plane like the Mustang and eliminated the need to buy an aftermarket muffler.

I'm sorry you got burned. It seems that just about everybody has had this experience in this hobby to one degree or the other. Mine was with with a couple of magazines and one expensive arf. Sounds like you took a much bigger hit, though.

Again, thanks for the reply.
