    Q: Can I Replace Just the Top Part of My Mini Heli Rotor?

      A: Yes, it is possible to just replace the top part. While this is not sold separately, it is often much easier to swap this part off of a new replacement set than it is to take off the entire rotor set and replace it.

      The only tool you will need is a paperclip. Straighten the paperclip. Use the paperclip to push out the metal pin that holds the top black plastic part to the black plastic shaft.

      Look at the side of the upper plastic part; you will see a metal pin in a hole in the side. Use the paperclip to push this pin out. Be careful not to lose the pin. Pop off the two plastic linkages, and the old upper plastic part will come off.

      Repeat this procedure to remove the same part from the new replacement rotor set. Put the new replacement part on the top of the old black plastic shaft, line up the hole in the side with the hole through the top of the black plastic shaft, and push the metal pin back in place. Pop the linkages back on and it is now ready to use.

    Q: How to fly your Mini Infrared Helicopter?

      A: Getting Started

    • Remove the Mini Heli from its packaging
    • Install 6 new alkaline batteries in the transmitter
    • Slide the door on the front of the transmitter open and unroll the charge cable
    • Connect the charge cable to the port on the side of the helicopter, with the helicopter turned off and the transmitter turned on
    • A green light with come on once it is charging, and go out when the charge is completed (The Red light may go out after about 10 minutes, but do not disconnect the helicopter until the Green light is out)

    • Flying the Mini Heli

    • Turn on the transmitter and the helicopter
    • Place the helicopter on the ground, or a flat surface
    • Push on the throttle stick until the helicopter begins to lift into the air
    • Once in the air, hover by increasing or decreasing the amount of throttle by small increments
    • Trim the helicopter by pressing the buttons labeled "ST.TRIM"
    • If the helicopter spins to the right, press the button labeled "L", and if it spins to the left, press the button labeled "R"
    • When adjusting the trim, press and release the buttons quickly, do not hold them down
    • If the helicopter spins rapidly, you may need to press the button ten or more times
    • If the spinning increases, try pressing the other button
    • Once the helicopter is hovering and trimmed, now it is time to enjoy flying it - use the throttle to move up and down, and the directional control to move left and right

    • Tweaking your Mini Heli

    • For a faster flight, add small amounts of weight to the nose of the helicopter
    • Troubleshooting

    • Mini Heli spins rapidly
      • First try trimming it as described above
      • If this does not work, check the tail rotor for damage, and replace if it is cracked
      • Check for hair or lint wrapped around the tail motor shaft, and remove carefully
      • When removing or replacing the tail rotor, ensure the tapered end is toward the motor, and the flares on the blades face outward
    • Mini Heli shakes strongly
      • Check the weights underneath the main rotor stabilizer
      • If the weight are loose, or have fallen out, keep them in place with CA glue, using the same amount on both sides to maintain balance
    • Mini Heli lacks power
      • Ensure the helicopter has been fully charged, if the transmitter batteries are not fresh, replace them and then charge the Mini Heli
      • If this does not work, try cycling the battery by discharging the helicopter by letting it run until the main rotor slows down, and then giving it a full charge
    • Mini Heli does not respond to controller
      • Replace the transmitter batteries with fresh alkaline batteries and then charge the helicopter
      • With the helicopter and transmitter on, try throttling up with the channel selection switch set to A, then B, then C
    • Mini Heli is out of trim each time it is turned on
      • This is normal; to make it easier you can count the number of times you have to press the trim adjustment. The next time you turn it on, simply press the trim button the same number of times
    • Mini Heli is hard to control right after being charged
      • When the helicopter is freshly charged it will have more power, this will smooth out as you use it, and should return to optimum power levels after the first minute of flight
      • To limit the initial power, try unplugging the helicopter a minute or two before the charge would normally finish
    • The tail of the Mini Heli is not straight
      • The tail should normally hold the tail motor in a flat position
      • If the tail has become un-aligned after a crash, it can be straightened by hand, but be gentle

    Q: How to Install a Mini IR Heli Main Rotor?

      A: In order to remove a mini IR helicopter main rotor, the main metal shaft must be held stationary with a pair of needle nose pliers, or a pair of thin vise grips. Grasp the shaft right below the bottom of the rotor, and while holding this stationary twist and pull the old damaged rotor off. If the old rotor is on too tightly to remove and you are comfortable using a sharp hobby knife you can shave off plastic off of the side of the main rotor shaft until you get down to the metal, essentially cutting the damaged rotor in half so it separates and removes easily.

      Once the old rotor is off, continue holding the metal shaft with pliers, and gently press the new rotor onto the shaft. The rotor only needs to go on far enough to have a snug fit, but you can get it on farther by holding the main shaft with pliers, turning the helicopter upside down and tapping the rotor against a hard surface like a counter top, driving the metal shaft in further. If the new rotor is loose, put a drop of CA glue or silicone adhesive on the metal shaft before sliding the rotor on, and allow adequate time for it to dry.

    Q: How to Pair Each Mini Heli Laser Battle So They Fly Independently

      A: You must pair each helicopter to its remote control each time you turn it on.

      Each Mini Heli Laser Battle Helicopter can actually run on any one of the 3 channels, and can be controlled by either one of the two transmitters (black infrared remote controllers). Each time you turn the helicopter ON it automatically locks itself to whatever transmitter it first receives a signal from. Each time you turn the helicopter off it resets itself and looses this assignment.

      Please follow these instructions each time you want to turn the helicopter on.

    • Make sure that both remotes and both helicopters are turned OFF.
    • Pick a remote, set it to “Channel A” and turn it on.
    • Pick a helicopter and turn it on.
    • Push up on the left stick (on the remote) to make the rotors spin.
    • Now this helicopter is paired with this remote and ready to fly on Channel A. Now do not touch the controls on this remote until after step 10.
    • Wait at least 5 seconds.
    • Take the second remote, set it to “Channel C” and turn it on.
    • Get the second helicopter and turn it on.
    • Push up on the left stick (on the remote) to make the rotors on this helicopter spin.
    • Now this second helicopter is ready to fly on Channel C.
    • Start your super battle planes!

    Q: Installing Replacement Blades onto my Bladerunner Heli?

      A: Installation of the rotors onto the Bladerunner, Micro Mosquito, and Firefly helicopters is quite simple.

      The rotors are held in a plastic “tube” called the Capping Tube located at the top of the rotor shaft.

    • Remove the plastic fitting tube. The capping will simply come off. -The next component is the Top Rotor, next there will be two spacers, followed by the bottom rotor.
    • Insert the base rotor with the stem down onto the motor unit; make sure it is the long stem facing the bottom rotor.
    • Line up the half circles inside the tube. Slide it down until the notches interlock.
    • Slide the two spacers down. They should be on top of the base rotor at this point. It does not matter which order you have the spacers in, they are the exact same.
    • Hold the bottom of the helicopter, and slide the Capping tube down to meet the top spacing tube

    • *Keep all small items in a bowl or jar to avoid losing the small parts.

    Q: What to do if your Mini IR Heli spins while you are flying it?

      A: How to adjust you Mini Heli?

      If your mini IR Heli (Mini Heli, Mini Bell, or Mini Lama) continually spins while you are flying it, there is a simple procedure to correct it.

      To make it stop spinning use the trim buttons labeled "ST.TRIM" on the transmitter. If the helicopter constantly rotates clockwise, to the right (when viewed from above) use the "L" button to trim it in the opposite direction of the spin. If the helicopter rotates counterclockwise, to the left, use the "R" button. Click (press & release) the trim button as many as 30 times while the helicopter is hovering in the air - don't just hold the trim button down.

      The helicopter must be turned on and hovering (even if it is spinning) while you press and release the appropriate trim button in order for it to work. The trim resets every time you turn the unit off, so reset it before each use.

      After the helicopter is correctly trimmed, you may still need to make adjustments during flight. Different throttle settings may cause the helicopter to rotate, so it is best to set the trim while it’s hovering.

      If the trim button has no effect after 30 clicks or more, try pressing the other trim button repeatedly in case the wrong trim button was initially used.

      If the heli continually spins counterclockwise (to the left) even after pressing the "R" trim button over 30 times, there may be something causing reduced power from the tail propeller.

      Check for hair or any other objects wrapped around the motor shaft going to the tail propeller. If there is any, gently pull the tail prop off and remove the hair. Ensure the tail propeller is installed the correct way, if it is on backwards the helicopter will not stop spinning even with full trim adjustment. Try taking the tail prop off and putting it on facing the opposite way. The correct orientation for the tail propeller is with the flares pointing away from the motor mount.
