Patrick,
Sorry about calling it an OS engine. The guy told me what the engine was & I forgot. So I called it an OS engine because that was the name brand that came to mind.
I talked to all the trainers at the local club here & they said they would love to train me on an Avistar but could not at the club field because of the club rules. Club rules state trainers will only train on flat bottom winged planes.
Like I said, I think this rule was instated because the club president owns the only hobby store in town. With that rule if people buy from him, then he gets to sell them 2 planes instead of one.
I really light the idea of semi semetrical wings to train on. That would be a way for me to learn to fly & then also have a plane to do more with once I did learn to fly. The only RTF semi semtrical plane that I have found so far is the Avistar. I like the wing span on the Tower Hobbies Trainer better than Avistar, but I want a plane that I can do more than fly in circles once I learn to fly it.
