hmmm, well when I get a bit more ambition I will take it back apart and take some pics for ya
yeah ok, I am an idiot, there is most certainly a place for the pin to connect to
I still haven't tried running it, i will try tomarrow sometime. While looking at these two K&B 3.5's side by side and my empty tc31 hull I had me a cool little idea
Would it, or would it not be totally sweet to put these two engines (If I can get them running!) side by side in the tc31 with two props etc

They fit in there so nice! That would be just awesome looking! I have no idea if that would be impossible to do or not, I would obviously need another set of running gear, and remove the stock one, fill the hole and make a dual setup. For twin engines, do you have to have counter rotating props, or can they both just run clockwise? But a dual fuel tank, dual .21 powered tc31 would be sick if it can be done. I have the whole snowy crappy wisconsin winter to do it, so do you guys think it would be possible???
