I've had about 8 flights now with my Whiplash and I have to say I'm impressed. Very fast and very stable. Very fast roll rate. The Rossi 53 is starting to loosen up. Running a APC 10x8 prop at the moment. No idea of the speed but fast.

However, I found that the engine vibration was loosening the mounting bolts. Kept tightening them up, but noticed that the vibration was fretting away the bolt holes, so all I was doing was pulling the bolt heads through the engine mount.

On the last flight a hot landing broke one of the engine mounting beams from the model. Has anybody got any ideas of how to fix it. I'm thinking of maybe removing the other one and letting in some wooden engine bearers. I need to think about this one before I do anything. Ideas are very welcome.

hey Bud - what's the internal structure like either side to the fuel tank bay??? Any other repair ideas??



I find I've got used to the speed now and want to go faster.
