Hi Andreas, we didn't weight the jet but it feels really light and fly's with the Falcon (23lbs of thrust) just a bit above half throttle.
The Cg is per instructions at 180mm.
What do you mean about raising the ailerons, we do not have that kind of setup on the Hawk. I do apply some up elevator when flaps are lowered to compensate for the pitch down tendency.
In this Hawk the flaps are very efective at 100% they slow the plane very nicelly letting you use throttle to bring it down. If you apply only half flaps the Hawk will float forever as it will loose speed very slowly.
You have to be carefull with high AOA and low speeds as the Hawk will drop a wing if it gets too slow. You need just a but positive to help it reduce speed and flare on final. We still need to install the fences on the wings and see how they perform.
