Hi Spacey

There were 3 Rushes at our field. Mine with a OS91FS, one with a Saito 72 and one with a OS91FX. I have flown them all and the one that would snap out was the OS91FX powered one. He had 2 servos in the back of the plane. IMO it was too tail heavy and made it too unstable. It was actually unpleasant to fly like this. Mine had one servo in the back and it was very stable with 45dec elevator throw. Try moving the cg forward a bit more. Let me know how it goes


Cheers
