Here's my Kangke Fun 50. I've had it for nearly three years and still enjoy flying it. The OS .65LA sips fuel and I'm running all standard servos on it.

Here's a video of it, taken a couple years ago. Since then I've gotten lower and crazier with it, and it has held up very well.

The picture with the plane upside-down is the result of me getting a little too low during an inverted pass! All that happened was the rudder tore off at the hings and the canopy was slightly pushed in. It was flying the next day after I glued the hinges back in [8D].
