I just installed add on #1 to get the J3 Cub to practice with before I fly my GP Cub ARF.

This plane (on the SIM) doesn't fly well at all. It wants to tip stall at speeds that should be reasonable for a CUB. My buddy has the actual plane (ARF) and it flies very well. I does not exhibit any tip stall tendencies at all.

Anyone have the same experience with this? How did you fix it??
