RE: Kat 40 Dude!!
Dude, I have ordered from both companies and they both give pretty good service. I had a little problem with OMP and a replacement plane. John did take care of the problem. I may have been a little impatient on the return, but it still only took a week. The Kat 40 is a great plane. I think you will enjoy it more than the funtana. It makes me look alot better than I really am.
As for as engines, I like the O.S. 46 AX. I've had several with out a problem. They fly the Kat 40 great.
