Bladerunner

If the bottom rotor blade on your Bladerunner RC helicopter is not spinning we can help you find the cause. The most popular reason is your rotor shaft is loose and the gears are not meshing together.

How to check if your Bladerunner’s rotor shaft is loose

You can check to see if your main rotor shaft is loose by firmly grasping the helicopter on the top and bottom of the canopy and moving the rotor shaft up and down. There should be at the most 1/16th of an inch of movement of the rotor shaft. If there is no play the rotor shaft, it will not spin freely. You can tighten up the rotor shaft by gently pushing down on the top of the main gears inside of the canopy while supporting the base of the rotor shaft on the corner of a table. If you tighten up the rotor shaft too much, and it does not spin freely, you can loosen it up by pushing down on the bottom of the helicopter (when it is upside down) while supporting the rotor shaft on a solid surface.

If the top rotor blade on your Bladerunner RC helicopter is not spinning we can help you find the cause. The two most popular causes are:

1. your main rotor shaft is loose and the gears are not meshing properly
2. a gear has fallen out of place inside your helicopter

First, check to see if your main rotor shaft is loose

You can do this by firmly grasping the helicopter on the top and bottom of the Bladerunner’s canopy and moving the rotor shaft up and down. There should be at the most 1/16th of an inch play. If there is no play the rotor shaft will not spin freely. You can tighten up the rotor shaft by gently pushing down on the top of the main gears while supporting the base of the rotor shaft on the corner of a table. If you tighten up the rotor shaft too much, and it does not spin freely, you can loosen it off by pushing down on the bottom of the main helicopter while supporting the rotor shaft on a solid surface.

If the top rotor still doesn’t spin

If the rotor shaft is in proper position and the top rotor still does not spin, then there is a gear inside of your helicopter which has popped loose. To repair this, you will have to remove the canopy. To remove the canopy, cut off the seam joining the top and bottom parts of the canopy. You should now be able to remove the canopy from the helicopter. You should now see a gear that has fallen loose, as well as a small metal pin which holds the gear in place. Using a piece of sandpaper, roughen up the bottom of the pin then use a small drop of glue to help hold the pin in place. You can now put the canopy back on using a few small pieces of scotch tape.

This Bladerunner spinning/rotating problem is due to the torque created by the spinning rotor blades and an imbalance in the pitch of the Bladerunner’s rotors. Since all Bladerunner series RC helicopters use the same general design of rotor blades (although different sizes) these instructions can be used for Bladerunner, Micro Mosquito and FireFly. If the rotor blades are not matched exactly, the helicopter will spin in one direction. This can usually be fixed by adjusting the trim on the transmitter.

If the Bladerunner RC helicopter continues to spin with the trim fully maxed out, you can remedy this easily:
Bladerunner Spins to the Left:
If the helicopter is spinning to the left, you will have to adjust the top rotor blades by bending more pitch into them. This is done by carefully bending the trailing (back) edge of the individual blades down.

Bladerunner Spins to the Right:
If the helicopter is spinning to the right, you can adjust the bottom rotor blades by bending more pitch into those blades. Use very light pressure to gradually bend the blades.

We also sell replacement rotor blades for all makes of Bladerunners.
