Right thrust is not going to help solve your problem. It takes pilot skill to take off a tail-dragger, that is why trainers have tricycle gear. What you are experiencing is "P-factor". When the plane is setting on the ground in the normal tail down attitude, the propellor blade traveling down or the right side of the plane hase more angle of attack than the blade on the left that is traveling up. Thus you have more "effective" pitch on the right side and it pulls the plane to the left. When the plane levels out, (tail rises) this creates eaqual angle of attack on both sides. There are also some forces created by the props slipstreeam swirling around the fuse and striking the fin and forcing it to right and makes the plane pull left. I think I said all that right.
You just need to learn the correct apllication af rudder elevator, and throttle. Once you get it down, it becomes second nature. Dont give up.
