Mine flys well on a saito 30. Take off at 1/2 throttle etc. (I also get torque effects on loops and throttle up.

The fuel tank split after about 30 flights and now i have fitted a larger one.

The CG on mine is way back from what they suggest but this doen't effect it. Landings have to be made with some throttle though or it can kartwheel on set-down.

I've also designed an "Amoco" sticker scheme. Looks much more colourful.
