Not sure what exactly happened, this is my first time with an X2.1 in the Plane. Armed, throttled up and when I threw it sharply rolled then nose dived about 10 feet off the ground.
Internal Compass was off turned off at the time.
Nano Talon AUGW ~668g (that may have been the issue)
mRo Neo-M8N Dual Compass
Titan Power 3S 3.5mAh
Just throwing it out there until I can take a look this weekend.
