Maidin- Everyone has to start somewhere, and crashing planes is inevitable- Most of the time the only way you can learn is to crash.

The plane you are starting with seems to be a good one-That is pretty cool that it came with a LiPo batt.
If you dont want to put landing gear on then dont. The prop will usually push out of the way. but you might want to put a strip of light weight tape along the bottom so you dont mess it up.

To learn how to hover, get up about 20 feet (or high enough so you can save yourself) and roll on the throttle to the point were the plane will support its own weight and pull back on the stick, when the plane is pointed straight up in the air give it a little bit of right aileron to compensate for the torque. Sooner or later you will learn what the plane does in a hover and will learn to react to it correctly.
Slowly start bringing the plane closer to the groundas you get better at keeping the plane in a good position.

Once you learn to hover it will open up a whole new world of aerobatics.
Oh yeah, make sure that your plane has enough power to go straight up vertically--or else you are going to get into some big trouble

Good Luck!
