when i went from stock to the graupners 10's the quad seemed to fly more like it did with the 8's, more responsive, etc.
im also running an f450 with 2814 motors, and its alot quieter then the stock dji's higher speed, etc.
also part of the hovering at midstick, for me it had more to do with verifying that in the software when the throttle was at midstick, the software said the same.
