Ken, what engine do you have on yours? I have either the .40LA or a Fox .45 I could put on it, I've never run the Fox but I did send it back in to the factory, they put a new ring (Ithink) and muffler on it and said it ran fine..the time I did fly the raid...it was tail heavy and very difficult to control,, took all I had to bring it in in one piece, and what would be a good prop for the Fox?..Rog
my big props are 7x3 and 6x3
