Out of curiosity, are you running full rates on your controls? I fly my Scout at 50% rates on the control surfaces, with 30% expo, and she's still more than responsive enough. She'll flip a tight loop and roll over faster than a pandering politician, but with the lower rates and expo, is much less twitchy at minor stick movement. My first few flights with the Scout, I had a bad problem with left roll on take-off from the motor torque. Reducing my take-off throttle to about half solved that, and she still lifts off just fine.
