Thanks for the help, went flying this AM, did a lot of takeoffs, found a slow advance of throttle helped as did right rudder. I was getting in some good straight takeoffs. Just for kicks, I was low and slow, about to touch down, then full throttle and the plane would immediately torque to the left; pretty cool. Nosing over is not a problem. The cause of ground looping is the center of mass is behind the mainwheels, I think. I might try moving the main gear back a little. I will also move the CG back as it is a little nose heavy now, this will be done for a change in flying rather than ground handling. Anyhow, thanks all, had a blast this morning, Mike.
