SOURCE: i have an apache 3 channel helicopter.the top

Same problem I had. There are two motors. One to spin the top blade and a second to spin the bottom. My motor was defective out of the box to spin the top blade. Very poor quality as my AH 64 had a bad circuit board. I had to take parts from one to fix the other.

SOURCE: heli max hicro helicopter just keeps spinning in circles

Spinning is caused by one of the main propellers rotating faster than the other. If both propellers are secured tightly to their drive shafts, the spin control knob on the remote control can be used to stop the spin. However, if one prop is slipping with respect to the other, the spin control knob will not fix the problem.
I've found that the set screws holding the propellers to the drive shafts tend to loosen after a while. If one prop is a bit loose and the other is tight, the relative slippage will cause the helicopter to spin.
To check, turn off helicopter power and manually rotate each propeller separately, watching the nylon gears in the body. If the propeller is moving and its drive shaft gear isn't, the propeller is slipping because its set screws are not applying enough pressure on the propeller's drive shaft.
Carefully tighten the set screw and the problem should be fixed. DON'T OVERTIGHTEN, or the plastic threads for the set screw will be stripped and the propeller assembly will be ruined.

Volitation helicopter just spins to the left on ground and will not lift off seems top blades are spinning much faster then bottom


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 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

Sometimes the metal weights fall out of the top rotating bar causing the blades to be out of balance and the bottom blade to hit the tail. Check to see if both the weights are in the top bar.

One rotor spins faster than other, so chopter flies only forward


Hi,
We are a family that bought one of your helicopters. We immediately had a problem, the top rotor stopped spinning after a crash. We found out that when the helicopter crashed I wasn't paying attention(I am 10 years old)and I was still pushing the throttle while it was on the top rotor. Big mistake,when I tried again it Didn't lift off the ground. We then put crazy glue in between the top rotor and the shaft and tried it again. It worked! Both rotors spun! Good luck!
