raptor g2 upgrade help please.
I purchased a new brushless motor and speed controller for my 1st raptor g2 i purchased. I hooked it all up nice and neat then when i went to fire it up the blades rotated slightly then stopped. Batt. was also a lipo upgrade,fully charged and purchased as a package upgrade deal with the heli. Is there a special set adjustment i need to perform? Im new to all this. Can you help me out Andy?
