The trick is... SLOWLY advance the throttle. If the wheels are aligned correctly it will do fine. If you have a habit of banging the throttle from idle to full the Cub will ground loop every time.

full up to start... let it get to rolling and slowly release the back-stick. The tail comes off the ground about 1/3 to 1/2 throttle (lower if overpowered) the plane should rise with no use of elevator by the time you are at 3/4 throttle (1/2 or 1/3 if you are REALLY overpowered) Touch up elevator... and watch it go up in a scale manner.

Piper Cubs are one of the best trainers... you can't beat it for FORCING the student to learn to fly correctly. You don't use rudder to coordinate the turn... the turn just plane looks bad. You don't learn proper throttle management... you ground loop like heck. If you want to head for warbirds such as a P-51... start learning on a Cub.

Cubs are EASY compared to this thing. (my "avitar" picture) If I slapped the throttle forward with this triplane... I'd spread it all over the runway. Cubs just exchange nose and tail... then try to go the other direction. (repeat untill you let off power)
