I just got mine together and had none of the problems mentioned except for the engine mount holes being slightly off. I just made do and forced the bolts home. Mine didn't fly quite as expected. I thought it would snap roll and spin better than it does. It is not much of a concern, however, I bought it just to practice hovering. I need to put high torque servos on the ailerons as the huge control surface is stalling out my standards. It rolls beter at slow speed than it does high speed because of this. I'm using the new Magnum .52 2-stoke and man what a sweet engine. The Magic hovers at 3/8 throttle with a apc 12.25x3.75 and balanced perfectly. The elevator pushrods could also use a little work but all in all, I'm pleased with the plane. Climbs out like a homesick angel.
