Hi,

Ok as to how do u put the nut on the bolts ?????? U DONT , comming from someone who has this plane........... thier is simply just no room........

I found you have to use Self Tapping Screws with a washer, just make sure the holes u drill are smaller than the thread of the self taping screws.... then simply put a washer over the screw and then screw it into the engine mount........ it should require a bit of force if it doesnt your holes have been drilled too big .............

Hope thats of some help..... PS (The GP Dead Center Hole Maker - Is an excellent tool makes this job soo simple) and good luck its a great flying plane and i have a 46 LA in mine and belive me its not slow with this in this model shifts
