SOURCE: heli max hicro helicopter just keeps spinning in circles

Make sure you used the right blades, the top and bottom blades are different parts and if you try to replace an upper blade with a lower blade it will mess up the flight. The two sets of blades are reversed, the leading edge is on the opposite side because they spin in opposite directions.

If you are sure you have the correct blades, try to eliminate vibrations, especially in the upper rotor. Vibrations can throw off the gyro sensor and cause the helicopter to spin. If it isn't vibrating then you need to adjust the trim. If it is just a slight spin, you can try using the horizontal trim adjustment on the left stick. If this is not able to correct the spin, set the horizontal trim on the left stick to center and then remove the plastic canopy. On the circuit board you will see two screw adjustments labeled "SENS" and "SCALE". First, draw a mark on both of them with a marker making sure to touch both the screw and the plastic or board. This mark will be used to reset the knobs to their original positions if you mess up. The "SENS" (sensitivity) knob adjusts how hard the helicopter responds to the gyro. The "SCALE" (rotor scale) adjusts the balance between the two rotors. If it is a smooth rotation (as opposed to a skittish, jumpy, or erratic rotation), you need to adjust the SCALE knob as one rotor is consistently faster than the other. On the other hand, if it is erratic and jumpy, randomly spinning in quick bursts, you should adjust the SENS knob. Erratic spinning is a result of the gyro detecting vibrations and overcompensating, throwing the helicopter in a circle. Play with these knobs, try just slight adjustments and keep going until it flies right. Have common sense, don't turn the knobs too far at once, just small adjustments will make it easier. Also if turning the knob one direction makes it worse, go the other direction. If you turn the SCALE knob too much you may lose lifting power because it will reduce the maximum power of one of the motors.

SOURCE: My Air Hogs Hawk Eye helicopter's lower rotor

Okey, this is a trickie one, now inside the lower rotor shaft the white plastic gear goes up in to the larger shaft and has like a simi circle on top, ( i know im not discribing it well but trust me the little "tooth" most likely has broke and it randomly binds up in side the shaft, had the same thing happen to mine, i fixed it by dissembling the rotor assembly and removing the broke "tooth" and putting a drop of crazy glue on the ******!!!!!! worked for me

SOURCE: My bottom blades on my Falcon X Helicopter

Hi,
I think the problem is the green pinion drive gear, either it has already crack on the sides that's why it moves to another position.
You could adjust the green gear by pushing it where the big gear( wheel ) turns. There is a screw at the side of the propeller where you could tighten it to the point it can have a contact with the green gear.
You could buy that green gear in the internet.You don't have to disassemble the whole thing.
Hope that helps you out.
Thanks for using FixYa!

SOURCE: Hi, I have a Walkera CB180d

The gap is causing you to loose power transfer. Replace the main gear and you should be back in the air. The CB180 is a fixed pitch, so as long as the blades are intact and straight, you can't do anything esle to them. Also make sure your battery is good and fully charged.

Is it the gears that make the helicopter just spin? I'm pretty sure I'm just new at this and I'd Like some feedback. Please and thank you


First you should post the model number and make.

Are you sure the blades are suppose to be opposite, you have different size blades on each rotor.

You have this on to smooth a surface, if you held the rotor the body would spin, same thing, the force of the blades is just making it spin on the surface.

Try putting it on cement surface, a driveway or carpet.

Syma s107 hit a dangling string that got tied up instantly and seized the rotors. now lights up but blades don't spin when throttled. What can I do besides replace the helicopter?


I was flying my syma s800g and hit the ceiling fan chain. When I attempted to fly it would spin and fall over. The problem was I broke the two small plastic pins on the top rotor holder. Ordered a new top rotor and flies fine. Then on my s107 I flew into a door and the top rotor had zero spin although the motors worked. In that case the screw that sets the top rotor onto the middle shaft loosened resulting in no lift and also tilted and fell over. This was fixed by securing the set screw properly. So in both instances it was similar effects due to the top rotors not spinning in sync with lower blades.

I recently got a DH-1 AeroQuest Mini Helicopter. It was working fine until I crashed it against the wall. So now the top Propeller spins but the bottom propeller does not and the helicopter just spins...


I had the same problem. Bottom blade would not spin. There are 2 shafts that spin 2 gears. The outer shaft that spins the bottom blade has 2 set screws and my set screws got sheered off. I replaced both set screws and everything works now....

My 9053 lifts off fine goes left right and reverse. but it goes reverse also when i want to go forward . Tail rotor turns at what appears proper rpm. and it changes direction when i push stick from reverse...


I own this heli also. The problem is that the tail rotor does not apply enough push to tilt the heli forward. It is this forward pitch that moves the heli forward. Aside form buying a stronger tail motor, upgrading your battery etc, the only thing you can do id this:

Get a credit card, a pair of scissors and some tape. Cut a couple of strips from the credit card about 2 1/2 - 3 times wider thhan the tail rotor blades and the same length. Now tape the strips to the top of the tail rotor blades. Make sure you don't increase the length.

This will help a little by providing more air push when the tail rotor in engaged. Without some serious modding, this heli will never be great.

I have more fun flying my micro size syma helicopter in the garage then I have flying my volitation. If there is even the slightest breeze, the volitation will float in the direction of the breeze and will not fly against it.

Helicopter is unbalanced


Hi. This is called "talk" its when the helicopter starts spinning instead of the blades, remote control helicopters and real ones.To stop this from happening you need to make sure the tail Rotor is going correctly OR probely the best thing to do would be take it back to the shop and get a hole new one.

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.
