Mystery Trex 450SE 450V2 Main Rotor Head Set Upgrade for 450 Rc Helicopter Unassembled

It's good but it's missing connectors to blade grips. Not included in set. Also its bad unusable due to miss alignment between hub and shaft. Oscilates and its unacceptable for flying. 3-4 degrees off. I'm mad about this purchase...

IT;S LOOK GREAT BUT to one micro screw broke esasy when asembly, no chance to test it
