Video tutorial if possible, but not necessarily.
My main concern is with landing. Looking for tips at what is a proper altitude decent. Altitude to runway ratio, proper speed control.
I sometimes approach too fast and "skip" on the runway, or sometimes I will drop too quickly and hit trees just short of the runway. And sometimes I'm able to land safely, I'd say 40% of the time.

Also any tips on speed control while trying to fly in formation, would be appreciated.
