Syma S107 Helicopter Problems & Solutions
The Syma S107 Infra Red Helicopter
Most Common Problems
*Short or no airtime (faulty battery, replace). Many people claim fitting a 240mAh Li-Po battery to upgrade from the default 180mAh (or 150mAh in some instances). However after much testing, the original batteries have proven to be the better option in the long run. Just buy another couple of extra 'copters to triple the flight time!
*Tail-motor failure (motor burnt out, replace).
*Model capable of low hover only or barely lifting off at all (the bottom rotor is probably slipping on shaft, push back down to click into place, a small spot of glue will do the trick if problem continues).
*T.B.E aka Toilet Bowl Effect (caused by a problem with the flybar). When your heli makes large circular motions whilst hovering, much like if the heli had been caught in a whirlpool. Not to be confused with the helicopter rotating upon its own axis! Either loosen/clean up fly-bar connecting links or replace entire top-rotor assembly.

* Slow drift whilst hovering - forwards or backwards (centre of gravity is off). Either relocate the battery by a few millimeters, add a small nose-weight or remove some tail-decorations.
Look after the Li-Po battery:
*Leave to cool-down after flight, (approx. ten minutes.)
*Charge via USB, (approx. fourty mins.)
* Leave the battery to cool-down post charge, (ten minutes.)
*Fly for five minutes, (Stop flight immediately as you notice the 'copter struggling to gain height!)
If you look after your Li-Po battery, it should hold charge for more than 100 charge cycles (8 or more hours of flight in total!)
*Flashing green LED light on controller, unresponsive throttle (due to poorly made transmitter cover). use fine sandpaper or a file on the Tx top cover to allow throttle to close fully.

This is probably the most frequently asked question and very much depends on your age, attention span, etc., About 95% or even more have had no problem learning to fly the S107 quickly. Most people I know have it sussed within the first few flights.
