I also built the great planes 60 kit about seven years ago. i built it with the clipped wing and a saito 91. The second year i had it an 81 year old fell on it and crushed the tail. I fixed that and hit a tree. Then i got into a midair with it in it's fifth year. Not to mention a couple of times upside down in a lake on floats when the wind got under it. But and i find this really hard to beleive i have never had to fix the fuselage. when i hit the tree i hit close enough to the fuse to break the prop but not hit the fuse. so i only had to repair the wing. it was caved in but no damage made it to the main spar so an easy fix. the midair i went thru a hanger 9 pizazz and it put a small hole in the wing covering and broke a little bit of sheeting. another easy fix. when the elevator and stab and rudder got crushed that took some thought to fix and was probably the hardest to fix. This plane is tough. I used the stock cowl. which was three piece abs plastic. in all honesty going to a fiberglass cowl would have saved me a lot of thought not to mention sanding and filling. Sometimes with the floats i wish i had a 120. But i like doing aerobatics. On wheels the saito 91 is plenty of power. And with the floats i can still do aerobatics but am closer to full throttle most of the time. Any other questions i will try and help you out if need be.
