dutchalltheway, I think it would be a good idea to do a dry run installing the elevator halves. The "U" shaped joiner can be tweeked a bit if the two halves are not on the same plane. Also expect to do a little filing to get the Futaba servos to fit. The Twist was designed to use JR servos which are a little smaller. I would install the engine last. You can slide the engine back and forth on the beams to balance it. That Super Tigre should be fantastic in the Twist. On my first twist, I shoved a little too hard when CAing the elevator hinges with a pin through the middle. The pin sank into the edge of the elevator and restricted the travel. I was able to loosen it up some by working the elevator, but it was still too stiff. If it was me, I'd go with the pinned hinges, but the CA's work good if you maintain the gap.
