I have the spoilerons reflexed up about a 1/4 inch, with a small amount of down elevator mix. usually when i flip on the spoilerons, the nose will pitch up slightly. i think that this plane could also be flown as a flying wing without the rudder booms as the ailerons are quite effective when used as spoilerons. i was also surprised when the plane lifted off by itself, and it went beautifully. i have a higher nose gear setup according to Opjose's suggestion, and i never had a problem with manually rotating the airplane up. in any case it has done the same thing on my other flights today, saving me the hassle of manually rotating the airplane. i think that the speed of the plane plays an important factor with the spoilerons, as when i flip on the spoilerons at 1/2 throttle or more, the plane climbs gently. it may not be for everyone, but it's worth a try if you have a long enough runway either blacktop or concrete. most of the times when i rotate manually, the plane will yaw to the left as if the speed is not quite enough for takeoff, but i use about 3/4 of the 350 meter runway to really build up speed before taking off.
