I recently purchased a Nexstar and got everything set up to fly. Since I've never flown before, I had it checked out by more experienced people at the field. It all looked good and was given the thumbs up to fly. I found a great instructor at the field, who was experienced with flying the Nexstar, and agreed to take it up to see how it flew. Before take-off, he advised me to remove the spoiler, the aileron, the AFS, and to increase the rudder throws. The take-off was beautiful, straight and level. He trimmed out all the controls and had the Nexstar flying without a hitch. I didn't want to bother him anymore that day since he was already giving instructions to another person.

A few days later, I returned to the field and found several people who had been flying for years and agreed to give me a lesson or two. The take-off by the instructor could be described as 'squirrely' and immediately after leaving the ground vear off violently to the right with a crash narrowly adverted. The plane was returned to the ground as soon as possible with the instructor saying they had never seen that kind of behavior out of a plane. So I packed it up and returned home a bit dispondent.

A few days later I ran into the original instructor and told him of the 2nd take-off experience. He took it off without any problems and without vearing off to the right, without modifying the plane in anyway. He said that the biggest thing to getting the plane to take-off straight and maintain straight, was to take off at 1/2-throttle. Anything more than that and the plane would always go right on take-off.

Hope this helps a little.
