HI,

Did you set the timing of the controller to the highest value? I'm running the Hacker Acro 90 with 30 degrees of timing, this really brings the motor alive.
and provides a big enough speed range. For really calm wheather i'm using a 21x12 APC-E, works fine aswell!

About the slowing down before landing, i'm slowing the plane down a lot on final, and then fly it in with some power. This high nose attitude makes beatifull landings.

Good luck
Winfried
