For some time now I have been wondering about how the center assembly of the !.20 Power twin is constructed. I can't seem to find pictures anywhere other than an assembled engine pics. From what I can see, the center housing is one piece so how is the crankshaft constructed???
If the center housing is one piece then either the front drive to the center crankshaft, or the crank for the rear engine must be removable to get the center shaft into the housing right? If so, how is that done so it wont come apart during running?
Also, This twin is alternate firing I think I read, doesn't seem possible with such a short center piece? Still trying to wrap my head around how this would be done unless very small ports are drilled which would limit power. Or is the intake angled some how???
A lot of questions I hope some one can answer for me. I tried to buy an engine but I can't seem to find one for under $300. I missed out on one on RCGroups the other day. Someone sold a marine version for $85. Must not have known what he had.... Oh well.
