> Did the airplane rotate at a reasonable speed? No... It rotates at about the same speed at whitch the gear must be retracted... However, I've erased all my work and I've started with a new config file created with AeroMatic. I've putted the contact points in the right positions and I tried to adjust this new file. At the beginning I tried to decrease the high take off speed with a progressive increments of the lift. Without any significative result... but I think that this time the problem is the postion of the CG. However I've got a nother problem. Immediatly after the take-off the airplane starts to roll to the right and I don't know how reduce or remove this effect. I've changed some of the values relative to the roll but this changes doesn't reduced the "auto-roll".
