I put 3 flights on this thing. It flies great. Definitely needs a lot of Crow to slow it down with K260. Knife Edges quite well even at low speeds. Low and slow is quite predictable. No bad tendencies detected yet.

must do's:

Get flaps geometry correct for reliable flaps operation.
If you use stock gear with stock Springs then do not modify them.
