i am really glad that this isnt a REAL helecopter. if you got it for christmas, you might want to return it- that is, after you verify that it is FULLY charged. this sounds like a half charged battery, that isnt spinning the bigger blades as fast as it should.
this could also be caused by any obstructions to the blades ability to rotate freely, something stuck to the blades- adding weight, bent blades, or internal belt/gear issues, regarding regulating the main blades, and the rear stabilizing blades timings.
if, before the charge, the dying battery caused the copter to crash, a blade could easily be bent, or have mud or something on it, weighing it down.
if the copter really is indestructable, i would go right back to a bad battery.
if the rechargeable battery got a memory after 4 days, i feel bad for you and your kids.
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!
My Hercules is a 3 channel heli,and I will try moving battery forward. On my SYMA s107 I turned the back blade upside down and got a dif style blade. It now goes Forward Great.
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 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.
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!
Hi This type of helicopter uses a fixed pitch blade. Have you recently replaced one or all the blades? If the blades are correctly positioned then once the motor comes to speed, the pitch of the blade creates enough lift to overcome the force of gravity. The problem you're having can only be that the motor is not coming to speed or the blades have been replaced but the pitch is now at the wrong angle.
