They make great videos.
I got sucked in and bought an 800mm BF109. I have since heard it described as a flying brick, but I think that's unfair to bricks everywhere, since I know I could keep one in the air longer than that plane.
To be fair, my first flight with it was my first flight ever and ended as you may guess. I shelved it until I was competent, rolls, loops, touch and goes with assorted Parkzone planes.
Took it off the shelf, set it up with a Spektrum Rx, programmed the DX6i and headed to the field. Same result as before. Hats off to anyone that can fly it, I certainly can't. I've salvaged the purchase and put the motor, esc and servos in a Slow Stick.
You get what you've paid for and you can't get parts. They never seem to resupply once out of stock, it seems shady to me, so I won't buy from them again.
