I got the free snare drum sound option with my Mach Racer too....[X(]
At first I flew it around at half throttle because I didn't know if the thing was going to blow-up,
or what....then finally after a couple flights I just threw caution to the wind and opened it up....
it flew fine. In fact I thought it was going to be squirrley, but it flys like a trainer in the turns....
very stable.
How many RPM's are you getting out of that Magnum ? If you have the usual 10-6 APC on it
your going nowhere with that junk prop.
FBD.
