Helicopter syma 9093 dragonfly tail pinion detached from shaft
After many flights, suddenly the tail rotor does not spin. I found that the tail motor shaft spins on itself and does not 'trasmit the movement' to the tail white plastic drive gear.
The motor metal pinion is not anymore attached to the motor shaft. Pinion-plastic gear alignment is ok.
Any suggestion? I guess I cannot simply glue them..
If I buy a new motor, will it come with the pinion firmly attached?

Have you checked that the main gears are not slipping as it only takes the drive on one set of blades to slip and you will not have enough powere to take off even though it seems both sets of rotors are spinning.
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.
Carefully, while holding the silver metal motor in place, gently pull the rotor off of the rear drive shaft. Place new one on and push it gently into place. If it is loose, you can secure it with a VERY CAREFULLY applied mini-drop of super glue. Turn helicopter upside down and use as little glue as possible, keep it away from where the shaft meets the motor, and keep upside down until glue dries fully.
Make sure you're charging fully, until the light on the charger doesn't get ANY brighter when you unplug the helicopter. Also, battery must be allowed to cool 10 minutes after flying AND another 10 minutes after charging. Most crucial is that you must never fully discharge battery. Fully draining a Li/Po even once (especially when it's new) can cripple or ruin your battery. As soon as you are unable to maintain altitude, land copter and power it off. Also, there is a button on the remote, labelled "tail motor speed switch" located near the trim control. With it in the "off" or up position the tail motor is much slower allowing for more precise control. When button is pushed to the down or "on" position, tail motor moves faster giving more tilt, and thereby much more forward/reverse 'thrust'. Verify that tail rotor is moving when right joystick is actuated (and that it reverses when right stick is pulled in opposite direction) and that it isn't loose on it's shaft... this can be tested by verifying tail rotor spin in one direction then reversing joystick... tail rotor should instantly start spinning in the other direction with NO hesitation, if it slows and then starts spinning in other direction or anything like that then it's loose. Turn helicopter upside down then VERY CAREFULLY apply a small drop of super glue where the shaft meets the tail rotor, be very cautious to not get any glue near where the shaft comes out of the motor, and do not turn right side up until glue is fully dry.

RE: Hover Lites Radio Controlled Helicopter parts
I have/had the same problems as everyone else.. I found that this helicopter is the same as 9093 Syma RC Helicopter, here is the site where you can get parts!
