a few things from the manual....

Speed brake
The speedbrake should open at least 80 degrees, and 90 degrees is possible. We set it on a
slider on the Transmitter for easy adjustment - depending on the wind conditions.
You can also open the speedbrake about 20 degrees during take-off, which helps the plane to
rotate at slower speeds.



Takeoffs and landings are easy, the plane tracks perfectly on the ground and slows down nicely
with the speedbrake. For slower take-off and landing speeds the ailerons can be lowered 5-8 mm
at the root. This increases the lift of the wing and slows the plane down, without making it critical.
Also a 20% extended speed brake helps to rotate the plane during take-off at slower speeds.
With the speedbrake fully deployed, the plane still needs to be brought in with a quite high angle
of attack to slow it down for small flying fields. So, don't worry about slowing the plane down and
getting the nose up in the last turn, even before the final approach.
