I have the GP F-15 with an o.s. 46fx up front. It's a nice plane, and moves right along at about 70 mph. If you like jet looks, then this is a good plane. It is a fun plane to fly if you like looking at a jet. But it is not much of an aerobat. It will do loops and rolls nicely though. It likes to fly fast. Wish I had a slightly bigger engine on mine. I fly off grass so only have an 11x6 prop on her. Had a 10x7 which flew much faster, but had trouble getting off the ground. with the 11x6, She gets off the ground much easier, but at a cost of some top end speed.
