I had the same problems on take off ( veering off to the right ) replaced the nose gear with a dual wire unit . This keeps the plane from puling (over center) under acceleration, causing the wheel to camber over resulting in to tracking even more to the right. The biggest improvement on take off was slow throttle input at no more than 1/2 max. once the plane is airborne then increase throttle. I did 14 touch and goes in a row last night with this plane. before I have learned this I was frightful of take offs , even ground looped it on take off and ripped the tail off of it.
I love this plane- it has got me hooked on this sport.
