Finally got her airborne on Saturday!
Using the OrangeRX 3-axis stabilisation (cheat-mode) she flies like there's not even a breeze.
I managed a few flights before the inevitable happened... A failed launch and since it belly lands, I tore out an aileron servo. I expected it to happen, maybe not quite so soon. It'll not take a lot to repair and add some protection, but I think it's going to be a great plane just to throw in the car and go.
