I self taught myself. First flight i took off and got her up in the air. But it never occurred to me that once up in the air at a safe altitude that I should reduce throttle. It was a flat bottom wing so at full throttle it got lots of lift and "ballooned" so high I lost it. Luckily I found it later and it survived!

If you have no help go ahead and try to fly by yourself. Just make sure you can't hurt anyone or their property.
