Thanks guys for all the great comments.

Mini Boy: I am pretty sure it is the motor. The motor used to have a click to it when you turned it and I could spin the main rotor pretty easy with the motor mounted. Now the main rotor is very hard to turn. I removed the motor and the click is gone and the shaft is very hard to turn.
Also it looks like the shaft has dropped down some how, maybe by about .25 inch. I can not see the shaft end on the motor top. Can not remember if I could before or not. When I switched out the battery pack for the second flight, the main rotor would not spin up. Even at full throttle it would not lift off. Anyone have experience with the Astro 20 for the Corona ????

And yes I am addicted to this It's the second most fun thing I've ever done [X(]
Can't wait to get the motor fixed and start flying again.
