Take some time looking things over. I have a Twist 150 that the hinges were not glued in well and were working out of the slots in the wing. I got the plane second hand and it had never flown, but it took a bit of work to get it ready. I ended up pinning all of the hinges but the ailerons and those I replaced with Robart Hinge points. It required removing some covering and gluing in some backup balsa for the hinge locations.

The other thing I found was that some of the ply formers were delaminating, espically the one the wing plugs into.

Spend some time to tgive it a close inspection before putting it in the air. It is a fun plane to fly though.
