Learn throttle control. This will cure the "climbing into the sky" tendency. Take off at full then back off to a little over half then trim it out for straight and level flight.

Every time you change throttle settings on a straight line, you will have to trim out the aircraft.

Learn to do this, (yeah, and everything else.. ) on the sim, but it is very important that you work with an instructor with a buddy box when you get into learning in the real world.

Mike.. where is that review? Is it on RCU yet?
