PROBLEM

Top rotors stop spinning. Is this normal? Is my unit defective?

EXPLANATION

When you first power up; both rotors are turning at a good rate. Now if you just let it sit there OR if you gradually give it power, the top rotor will stop spinning. The reason is that the built in gyro is not sensing a need for the top rotor to counteract the rotational force of the bottom blades. In other words the heli itself is NOT spinning and the gyro does not see the need to turn on, or increase speed on the top blades. Hence they stop turning or sometimes slow down to a stop. 

SOLUTION

When you power up, give it enough throttle (quick) enough to get it off the ground. Once you do this the built in gyro senses the bottom rotor trying to spin the heli one way and therefore it tells the top rotor to counteract the spin by increasing or decreasing its speed. If this does not solve the problem then there may have been a missed or incorrectly executed step in the binding process. Example: Helicopter was moved or tilted before binding was completed throwing off the gyro. Power off the heli and radio, wait a few seconds and then reconnect.

PROBLEM

The Fusion Helicopter suddenly tipped sideways during flight and crashed. It is defective and I want free parts or a replacement.

EXPLANATION

The Fusion is a fixed pitch coaxial helicopter. Such models get blown around by wind and are only suitable for indoor flying. It is mechanically impossible for the Fusion to tip itself over or be accidentally or intentionally tipped through user control inputs (we have tried). The environment in which you place your Fusion makes a big difference.

SOLUTION

Find an indoor space with a lot of room where you feel comfortable learning to fly. Close windows, doors and any other possible source of moving air that may blow your helicopter out of the air. Take off from and land on a smooth surface; stay away from carpet or grass that can potentially snag your landing skid and end your flight before you even take off or make your landing rougher than expected.
