It's true the Cessna isn't a trainer, but even truer that you simply must get somebody to help you at least with the first flight.

If you aren't used to building models, even getting one already built ready for flying, you are bound to need to trim it the first time up, and that is not easy, even for somebody who has become proficient with a high wing model.

Put it this way, if you fly it by yourself the first time, you are very likely (yes, I'm afraid very likely) to have a first flight that lasts 10 seconds or less, and you won't get the opportunity to get up the learning curve enough to enjoy it. Please get an instructor. It'll pretty much insure you will get to a stage where you can start to get the bug and it won't cost you a fortune in time and money. From what you have already said, you sound as if you will learn very quickly, and that instructor will very quickly become redundant!

Good luck and welcome to a great hobby!
