I just wanted to say to all the people who cant get there planes to take off it has to depend on engine placement, wing placement, and wing angle, my first plane i had to take it to the end of the runway to even try to get it in the air after the little fall/jump on the end of the runway about 75% it succeeded but after fiddling around with the wing angle i got it to take off 35 meters before the end of the runway. So anyone who is having trouble with there planes look at your design and using the wings he supplied you with helps alot better then the stock i tried stock and the plane wont even take off.
