I had a Propel orbit hd which flew away. Second one i lost. But if u have a button for instant landing or somesuch. That used to start my rotors spinning. It is like in front of ctrl arm for speed. The directions they give were useless.

Patel tighten screws o n props. That is causing it

Propel just shot strsightup past my control. It finally came down in thick woods. This is the 2 one i have lost like this. Wont buy another
