Have beeb flying for a year now and no trouble taking off any of my planes-nose grear or tail draggers. I figured the Cub would be no problem. Have an OS 52 four stroke in it and it is set up properly-CG , throws etc. BUT, I can't get it up to enough speed before she wants to lift off, stall and crash. I try to get it running with very little elevator just to keep the tail down on initial roll out, let the elevator neutral out and let her climb out . It has worked a couple of times but after three crashes on take off this brand new beauty is starting to look pretty beat up. One of my buddies has a Goldberg Cub and no problems. He is flying it with a Saito 65 4 stroke. Anybody out there flying this H9 Cub? What's your experience with the take offs. Some guys say all Cubs are a bear for trying to get off the ground safely. Any words of wisdom would be appreciated.
