I agree with rkramer about the rudder. My tailwheel was very well attached to the rudder, and eventually pulled the CA hinges loose from the tail.

Canopy- When you glue it on, put the assembly back on the model to dry. Mine was not done that way and when I put it back on the model, the hatch didn't fit. Used an x-acto to cut some of the glue loose. Slipped and cut my thumb. Visit to the ER, 5 stitches, $700. Save yourself the trouble.

Pushrods- The directions are confusing as to what goes where (no pictures) The bulkheads can only be facing one way and have the holes line up correctly. The pushrod tubes cross over in the middle of the fuselage. Also, be sure you come out the correct slot when you get to the tail (upper vs lower). I got mine reversed and had to do a lot of creative wire bending to make everything work.

Landing gear- Mine's broken out a couple of times. Might consider beefing that area up a little. The aluminum gear also got bent pretty easily after a few firm landings. Using Du-Bro dural gear now with good success.
