I bought the model second hand still in box and am pleased with its build quality.

She had her maiden today. Took off in 15-20 feet what a wonderful bird!. Flew nice and gentle and I was happy with the punch provided by the setup.

The motor and ESC were almost cool to touch and the battery was the good kind of warm, but going to cut some vents in the fuse to vent battery heat anyway.

I think she was up for about 4-5mins with quite a lot of WOT, I landed and still had 3.7v in each cell and put about 3300mah back in)

Im looking forward to flying again next Sunday
