RC Helicopters

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.

If the Micro Mosquito or Firefly will not fly there may be a problem with the rotor blades. Use the simple steps below to troubleshoot possible causes. We hope you can find the solution. If your rotor blades are broken we sell replacement Micro Mosquito & Firefly rotor blades. Order online or by phone: 1-800-979-9794 / 306-955-9907.

1. Ensure that when the rotor blades spin they are rotating in opposite directions. If they both rotate in the same direction, it won’t fly. If this is the case, make sure that the upper large gear only meshes with the upper small motor gear, and that the lower large gear only meshes lower small motor gear.
2. Check that the lower rotor is the one with the two notches in the bottom of its stem, and that those two notches interlock fully with the notches on the top of the large gear.
3. Ensure that the blades are on the right way, and that the trailing edge of the blades curve down. If the trailing edge of the blades curve up remove the rotor, flip it over, and re-install.
4. Check for excessive free play in the main shaft by gently tugging up and down on the top of the shaft while holding the body of the mosquito. If it moves up and down more than 1/32″ (0.8mm) then press the large lower gear down on the shaft while pushing up on the cap on the bottom of the shaft until this free play is reduced, but do not eliminate it entirely. If there is no free play at all, or the shaft does not spin freely, increase the free play by pulling up on the large lower gear.
5. Check for free play in the spacer between the two blades by gently sliding it up and down while holding the shaft. If there is more than 1/32″ (0.8mm) of free play, press the transparent retainer at the top of the shaft down until this free play is reduced, but do not eliminate it entirely. If there is no free play at all, or the spacer can not be rotated with out resistance while the shaft is held stationary, increase the free play by pulling up on the transparent retainer at the top of the shaft.
6. The trailing edge of the blades normally curve down. If they have flattened out over time, they may need to be gently re-curved by hand, in order for them to provide enough lift.
7. Over time, friction may cause the build up of powdered plastic where the main shaft goes through the large upper gear, the lower rotor, and the spacer. Removing these parts and cleaning them by passing a small pipe cleaner or a very small rolled up strip of paper towel can improve flight performance.
8. If the helicopter will fly but is not stable, ensure that the four metal pins that make up the pivot points of the universal joint at the center hub of each of the two rotors are all present. If any of the pins are missing, replace the rotor.

After many hours of flying your Micro Mosquito / Firefly main drive motors may begin to fade and wear out. Don’t worry, we have new replacement parts. All you’ll need is a soldering iron, solder, some tape, a Phillips screwdriver and a flathead screwdriver. Follow the simple steps below and you’ll be flying around the house in no time.

1. Remove the “C” clip that holds on the rotor shaft. It is located on the underside of the unit near the middle. It will pull out towards the back. The rotor shaft, gears, and rotors should then be able to pull upwards out of the main body. Please be careful not to break any of the gear teeth when taking them out of the motor pinions.
2. The motor pinions should slide off just by pulling on them. If more force is needed, use a small flathead driver to pry the pinions off. Place them in a bowl or jar for safekeeping. Many of the parts on this unit are very small, and are easily misplaced. Make a note of which pinion goes on which side.
3. Remove all of the small screws from the bottom of the body. There will be 3 on either side and one in the middle for a total of 7. There will be two more on either motor you will have to remove.
4. Remove the caps on the bottom of the motors. They are just held on by friction and a bit of glue. They will just pull off.
5. Open up the body between the front LEDs. A small flathead screw driver will suffice. There will be a single screw holding in the circuit board down. Remove it.
6. Release the motors by pushing them up through the bottom, and out through the middle of the body. You should have access to the wiring then. If there are some problems getting the motors out of their mounts (pull halfway out, then stop) you may have a later version of the Micro Mosquito / FireFly that has an extra ground point on the motors. This can be snipped off and resoldered on later.
7. The next step will be to remove the motors. Snip one wire at a time, trying to keep the length of the wires leads close to what the new motors have. There isn’t a ton of space underneath and more wiring can cause putting the body together tricky.
8. Basic soldering of the wires together will follow. Strip the ends of the wire and pre-tin the exposed areas. Use heat shrink or tape to seal the connections.
9. Place the new motors back into the body, making sure if you have the ground points on the motor, to resolder them. Attach everything back together, making sure that none of the wires are being pinched by the two body halves.
10. Place back in all of the screws and you’ll be back up in the air!

A radio controlled electric helicopter can provide you with hours of fun. Unlike an airplane, you are able to hover in one spot, or move from point to point at will.

Firefly and BladeRunner Helicopters:
Both the Firefly and the BladeRunner helicopter use counter-rotating blades to achieve incredibly stable flight. These helicopters are for indoor use and are perfect for beginners. On the transmitter, the first control stick gives you fully proportional throttle control allowing you to move up and down with precision. The second control stick operates the steering, left and right. The helicopter achieves this by changing the speed of the counter-rotating main blades, creating more torque in one direction, causing the helicopter to spin.

Draganflyer Helicopters:
The Draganflyer is a professional, hobby grade, radio controlled, electric helicopter, suitable for flying outdoors. Unlike a standard helicopter, the Draganflyer has four rotors, one at each corner. With four channels used to control movement, you have fully proportional control over throttle, yaw, pitch, and roll.

The Draganflyer’s power source, a three cell lithium polymer (li-poly) battery, gives you 12-15 minute flight times. The Draganflyer is available in five different models, the Draganflyer V Ti, V Ti Pro, SAVS, TSU, and X-Pro. The Draganflyer V Ti is available with or without a wireless video camera system. The Draganflyer V Ti Pro adds frame bracing, a computerized transmitter, and a 460 line high-resolution wireless video camera system. The Draganflyer SAVS (Stabilized Aerial Video System) is the top of the line for professional video use. Equipped with our highest resolution 480 line wireless video camera system, anti-vibration camera mount, hard shell transport case, and Diversity video receiver in its own base station case. The remaining two models fall into the industrial category. The Draganflyer TSU (Tactical Surveillance Unit) is customized exclusively for military, government, and law enforcement use. The Draganflyer X-Pro is a larger version, about twice the size of the other four. It is intended for applications that require a larger payload.

Which Draganflyer Helicopter Is Best For Me?:
If you are starting out, and would like to focus on flying rather than video, the Draganflyer V Ti would be a good choice. It is also available with a wireless video camera system perfect for taking amateur video. If you would like to get into higher quality video, the Draganflyer V Ti Pro with its 460 line 1/3″ CCD video camera is for you. For the highest video quality and all the extras, the SAVS (Stabilized Aerial Video System) is your best choice.
