If one blade is spinning faster than another, then the helicopter won't lift off. The first thing to check is the gears driving the blade shafts. It could be that one of the gears is not set properly, or there is something caught near the shaft. Pet hair can often wrap around the shaft and cause drag. If the gears appear to be in the correct positions, and meshing with the pinions (small gears) on the motors, and there is nothing wrapped around the shaft, such as hair, I would slowly increase power and see if both motors start spinning at the same time. If they don't, there could be a problem with the motor, or the controller board. If this is the case, it may be repairable, but might be just as cheap to replace the whole helicopter.Hope this helps!

The receiver is not binding to the transmitter. Make sure the batteries are in good shape in transmitter. I'm assuming it's a 2.4GHz radio frequency. When you are about to fly, turn transmitter on first after 4-5 seconds turn heli on or plug battery in on heli. In the manual there should be a page describing radio binding. It will describe on what gimbles to move and in certain sequences to complete the process. When the light on transmitter stops flashing means the binding process is complete. Hope this helps.

Check that the antenna isn't rubbing against the chassis as mine got rubbed thru and I think shorted the sensor. After trying playing with the left switch on the remote about 20-30 times it synced again with my chopper and I touched the open antenna wire purposely against the chasis and it would lose signal, then I removed it and it worked again. Tried that a few times so I think it's rubbing against something causing it to short out.

Lift is a function of the aerofoil. See that heptr blades are not bent or you or someone else have not tried to straighten the blades. They are at a specific angle to provide the required lift.

The top of the main shaft is probably broken. There are 2 pins that hold the "head" for the main blades straight and are probably sheared off. This is causing the balance bar to hit the blades and cause it to crash. You could try the crash kit here: http://www.helipal.com/spare-part_v-max-parts_syma-s107.html

Look for a little switch on the bottom or towards the bottom on either side. Or maybe near the charge port.

hi ,
the problem is not on the trim its the forward backward button make sure that the blades on the tails engaged when you pushed the forward button check the blade if it is not broken or is spinning to its full speed replace the motor.good luck!

Check the connection on the control board. The square plug may have come loose.
