I got hold of a preowned CMPRO Cessna 46. The ex owner flew electric and crashed wrecking the firewall and needed a rebuilt which he didn't bother. I got the plane as a result. What I did was simply cut a piece of hard ply the size of the firewall and epoxy it down. I was using an SK 50 swinging a 13x4 prop. My initial CG was way back but what the heck I brought it off for a maiden flight and nearly crashed it! The plane just climbed so nose high that no amount of down elevator could compensate.

lucky I managed to make an emergency landing after a few heart wrenching spirals and wing dropping. The landing gear nose wire was a gonner and the firewall gave way. I guess the epoxy was not enough. This time round, I gave it a good layer of epoxy and hope it holds. I had an SK 90 so I made some adjustments and fitted the bigger engine in, after which I checked the CG this time round, it blances way better into the 65 mm mark. I have yet to bring this plane up. I hate puttingt in dead weight and for the start, I do not have so much weight. So I though the bigger engine would balance better. However, I have never overpower any plane by such a big extent. Do you folks think this plane would fly with an SK90?

I have also attached pics.
