My 11 year old son soloed today! He flew a couple flights take off to landing with me on the buddy box and I never let go of the trainer switch. He said, "Dad, I want to solo". With our buddy box system, he was always on my computer radio. So, his solo was the first time he used the non-computer radio. When he picked up the radio he accidently slid the aileron trim all the way to the right. Me, not knowing this, watched him fuel up, start the engine, and take off. So, the Nexstar takes off. He brings it around and casually says "it keeps banking to the right". I look down at the radio and see the trim and bring it back to center. After about 8 minutes he brings it in for a nice three point landing. We then went over how the trim settings work. My mistake, as I obviously should have done this before take off. [X(] We are flying off a dry lake bed so we can take off and land pretty much anywhere. We always "pretend" that there is a runway for practice, and he landed right on it. He flew four more times, with one abborted landing and go around. I think I have created a MONSTER!
