OK... I REALLY want to get to the bottom of why some guys love the plane, and some guys are having trouble. First and formost airleron neutral is extreamly critical. secondly, Nose heavy is bad. Third, it is much more tolerant to tail heavy. If you vary the CG...go back from 6" but NEVER forward of the 6" mark. Mayby I am overlooking the biggest thing...this is not a hammer the throttle and fly like a sport plane plane. The reason Im saying this is because there is a trend that I am starting to notice...when I read flight reports from the funfly pilots who try the Spa3d, they love it, but I've noticed that the guys who are having trouble may, to the best of my knowledge, not have funfly experience. When you guys fly it, are you going full throttle for take off, and expecting to fly around at full throttle? If so...we may be getting close to why some are having trouble, because this is not a sport plane. Yes I can fly mine at full throttle, but only for short periods of time and I don't push it. Stuff flexes and all kinds of wierd aerodynamics start happening especially in anything other than straight and level at full power. When I fly mine, once airborne, on a normal take off, once the wheels leave the ground, the throttle is backed down to approx half. More than half throttle is never used unless it's for a hover maneuver, vertical climb out, kicking the tail around in short bursts, or feeding power into an already established flat spin. A funfly plane is not made for cruizing fast...it is made to be positioned in the sky for various stunts, which are performed with barndoor throws and precise throttle managment. The plane is designed to crawl in harrier, hover, tumble and flat spin...not haul butt. They will fly around fine conventionally, but anything beyond half throttle is pushing it...which is why in the instructions I mention that comon sense must be used along with the throttle. Ross, your plane is the third plane that I have seen pictures of, that I see absolutely no reason whatsoever why you aren't having a BLAST with. And so far, these "not so good" reports are coming from the Spad forum or Spadworld, however, when I go to the funfly forum, these things are growing in popularity and guys are loving them. Is it possible that the difference between funflying and sportflying may be misunderstood and contributing to higher speed misconceptions and guys having wild rides with these planes? If I'm wrong I apologize, and we must keep looking for why some guys love em and some guys are having trouble.
Oh, and a note about Expo. I don't even own a radio with expo, so I don't have any experience with it, and have never used it on anything. I had to ask Kraut what it even was when it started coming up on the forums.

As for your plane, definately try the slight aileron reflex. On my first PQHOR, that was the difference between a solid airplane and an almost unflyable airplane...the rons were parallel at the fuselage, but drooping at the tips.
