RE: moki reverse crank
Hey Hanna
Have you tried to contact Moki to see if they can provide you with one? I know Hobby People is coming out with a 210 and 180 2 stroke and they are dead ringers for the Mokis. But of course they aren't Moki (wink wink)
What prop are you going to use on the revese engine? A pusher?
I know I've heard of a gasser engine that can be revesed but can remember who. Try an internet search.
A p-38 with counter rotating props is well worth the effort.
Good luck!
