RE: prop size
The props are surprisingly sharp too [X(] Be careful, and use a chicken stick to start it with.
A simulator of some kind will help a great deal b4 you go it alone. I learned by myself (still learning), it can be expensive, at times frustrating, and time consuming. It also takes a great deal of patience. If you can find help somewhere, anywhere, even if you have to travel, it would be well worth it. I taught myself on an Aerobird, then moved on to my trainer. The Aerobird is a very sturdy plane, survives crashes well, you will crash. But its also very hard to handle in any kind of wind over 8 mph. I almost lost it (literally almost dissapeared into the horizon) one day, the gusts were up to 15 mph. It just doesn't have the power or weight for that kind of wind. Your trainer should be fine, but don't try to learn on windy/gusty days, until you start to get the hang of it. Anyway, be safe, do pre-flight checks b4 every flight, have fun, and let us know what happens. Sorry, one more time, Please try to find someone to help, you won't regret it.
