Failure to lower the throttle stick to the lowest possible position in the event of a crash
could result in damage to the ESCs in the 5-in-1 unit, which may require replacement of the
5-in-1 unit.
Note: Crash damage is not covered under warranty.
Once you have gained experience and confidence in hovering the Blade mCX2, you can attempt more
advanced maneuvers including:
Forward Flight Backward Flight Skidding Takeoffs
Pirouettes Spot Landings Skidding Landings
Advanced Swashplate Settings
Short Swashplate
Control Balls
Long Swashplate
Control Balls
The Blade mCX2 comes with an adjustable swashplate. Advanced pilots may benefit from a more
aggressive setup. To achieve a more aggressive setup, pop off the lower rotor head links and move them
onto the longer set of inner swashplate control balls.
