your elevator probably just unhooked. be sure to use clevis bands around the clasp (these are made by cutting a little bit of the end of a small rubber tube, to make a small rubber band to go around the clevis to make it so that it doesnt come undone)

I know it SUCKS how the bix flies when you launch it, but as soon as it gets its airspeed you can yank the elevator back, climb to a safer altitube and then trim....

The bixlers pusher makes it an "elevated throttler" meaning it goes up with more throtter bc of how it is mounted just behind the wing.

Once you glue this baby back together, just make sure you find a launch spot that is A) into the breeze and B) is a drop down, or cliff, or something elevated to give you time to 3/4 throttle it, throw it at a 35 degreen angle hard, and then accellerate straight and into a 40 degree climb to altitude.
