I had two of them and I had to add balsa shear webbing to the wings on the leading and trailing edge side of the wings and stabs ( the first batches had none). The plane was much, much... better once I took all the elasatic type rebound "flex" out of the wings (very bad). I eventually gave mine away to two guys entering pattern..., as I moved on to other products.

The carbon tube landing gear design works ok, but not great. I eventually went to regular gear after I hit a hole in the runway and snapped one in half at a contest. I flew mine with a OS 140 RX with the wings positioned in the forward position and I think I had a 1/16 shim under the front wing anchor tab for additional + incidence.

They fly good.... best of luck. I still have fuse/stab covers for mine,if you need any, you can have them if you're interested.
