Hello all, this is my first post on this forum.... I started with a cx-2 which I fly pretty good, I went to a Real Flite G-4 simulator which I have trouble with some heli's, I went ahead and bought a Blade 400 and tried to hover, I lifted to high, panicked and cut the power, she landed kinda hard and bent the main and feathering shaft, I now know how to repair those.. second flight, I went through one battery lifting a foot and landing, a little rough but no crash, then on second battery I lifted about 10 feet and tilted sideways and down to earth! Another main,feathering,main gear, servo,blade griper and flybar

.
I just read about changing a setting in my radio, the expo to 25% which I programed to one switch to activate, is this a good idea?
