i just recently got a spacewalker 2 by seagull. today was my first day trying to fly the thing. I an coming from an lt 40 kadet. The problem i had today was for one it hard as **** to keep the thing going straight during take off. second i am not use to the wheel on the tail and when the wheel leaves the ground the plane starts pulling to the left. I was at full speed and tried to give it full up elevator (which is set at 3/8" up/down) the plane started to leave the ground but would not gain altitude and finally landed hard in the grass. Now I am scared to try and take it up again. the manual for the plane says to set the throws as follows.
elevator: 3/8 up/down
ailerons: 2/16 up/down
rudder: 1" right/left


any advice would be greatly appreciated
