It snapped to the right upon takeoff, I was about 3-4 feet high. no real damage to bipe. (it even bounced and landed back on the wheels, and, as we all know, no matter what, if it ends up on the wheels it's not a crash I'm new at bipes, been flying 5 years but my first bipe. I'm pretty sure it was due to lack of airspeed. I've flown it since once and just got plenty of airspeed and it went okay.
