The Extra 33D is what happens when you have a custom built 37% Extra 300 with the 3D chip installed in the designer. I did not designed the orignal plane, I redesigned the tail surfaces and the ailerons to be larger than any other currently offered bird. The surfaces look like they could have come off a profile. It is a Pro Bro approved plane.

I do not know the weight of the Mini-Flip, however my buddy has one with a Satio 40 on it and he likes it. I have not seen it fly, yet.
