I have well over 20 gallons of glow fuel through my ST-90. I liked it so much, I bought a back-up which is ready to go, just in case. ( I don't fly either of them any more).

The behavior you are describing in your Original Post is nothing like what I have experienced. My CG is WELL behind recommended and the plane is as stable as can be. It rocks like crazy in harriers, but that is because I am still new and learning harriers.

I had to change my servos, hinges, batts and add regs; because the recommended setup is JUNK. You will not be happy with the recommended set-up. This plane needs 8411's and 8611a on rudder to fly right. (or equivalent).

I never bothered to set any rates. This plane is fine at maximum throws and tons of expo.

Good Luck!!!
