Can it be your control throws? Mine snap rolls as fast or faster than any plane I've ever seen before. Are you using high rates... how high? I've got mine max'd out bevel to bevel or as close as it will go. Low rate snaps are slow but don't blink when I do a high rate snap or you'll miss it. That is probably my favorite thing about this plane. When I get a chance to get shoot some video, I'll show ya.

I know that I can produce 4 different "looks" to my snaps based on what combination of rates I use...

All low produces a slow lethargic but graceful snap.

High Elevator only gives me a fairly quick snap, but more tumbling than axial.

High Elevator and Rudder gives me a pretty quick snap but more "angular" vs tumbling.

High Aileron and Rudder gives me lightning fast snaps, somewhat more axial since the elevator is low rate... but still a snap roll, not axial roll.

They are all snaps with full stick on every surface, but I get different "personalities" of snap with the different combinations of rates. The one with bevel to bevel aileron and rudder is the fastest, as long as I DON'T throw high rate elevator in... THAT WILL SLOW IT WAY DOWN.
