V388 helicopter, fully charged but as soon as you try to fly it the rotors start to move then the whole plane switches off.

Helicopter should be powered off when charging. After fully charged (charging light as bright as it gets) and given 10 minutes to cool after charging, turn on helicopter first and place on level surface, this allows gyroscopes to sync up. Then, after making sure the main rotor control (left joystick) is all the way down, turn on controller, and quickly push left joystick all the way up (just until the blades move) and back down. This will link them. Also, make sure the antenna is still wrapped around the landing strut and not contacting any metal on the craft. And of course, good batteries in the remote, and ALWAYS let helicopter battery cool for 10 minutes after charging AND after flying. Also, NEVER fully drain battery, as soon as you cannot maintain altitude, land and power off. Fully discharging a Li/Po battery will weaken it severely, and sometimes kill it.

Please let me know if this helps, I love Syma helicopters, but they can be tricky sometimes...

Sadly, Bob is incorrect here. In a coaxial helicopter, the main rotors spin in opposite directions, equalizing the centrifugal force and allowing the craft to hover without spinning, fine-tuned by the adjustment of the trim control. The counter-rotating main blades and internal gyroscopes provide a stable hover, while the tail rotor serves only to push the rear of the chopper up or down, providing the forward/backward thrust. If you are not moving the right joystick, you tail rotor should be stationary, or perhaps moving lazily from the wash of the main rotors. Sounds like a charging issue. What type of charger are you using? Also, Li/Po batteries are not meant to be fully discharged. Fully draining a Li/Po too many times, ESPECIALLY when they are new, will ruin them. Luckily the batteries on an 032 are easily replaceable. Available on Amazon and many other online retailers, and replaced in about 1 minute with only a small screwdriver. With a new Li/Po, charge them FULLY with the correct charger, and always stop the flight as soon as you are having to give it full power to maintain altitude. Also CRUCIAL is you MUST MUST MUST let the battery rest and cool for after a flight, wait a good 10 minutes BEFORE you connect the heli to the charger, and another 10 minute cool down after charging before you fly.
Hope this helps

0) Obviously, helicopter will operate best when fully charged... if charging light gets brighter when unplugged from helicopter, then it's not at full charge. Charge fully, then allow battery to cool for 10 minutes. Good batteries in remote also.
1) Power on helicopter.
2) Place on level surface and let gyroscopes sync. There is a red light inside the body (NOT the red/blue flasher in the nose) that will blink when you turn helicopter on, and will keep blinking until craft is level and stable for a few seconds, then will stop blinking.
3) Make sure left joystick is all the way down.
4) Power on remote.
5) Throttle up (left joystick) until blades move and then all the way back down.
This should get you flying. Let me know.

Batteries are available online (amazon and many others) and change easily with only small screwdriver. Overcharging is not the issue. Nearly impossible with PCB (overcharge prevention circuit) hard wired into battery AND in charger. Problem is likely UNDERcharging, overDIScharging, or improper battery care. Battery MUST be allowed to cool 10 minutes after flying. Charge until light on charger doesn't get any brighter when helicopter is unplugged... light comes on (dim at first) well before full charge. 10 minute cool-down after charge also a MUST. And, most important, when flying, as soon as you are unable to maintain altitude, land helicopter and power it off. Li/Po batteries should never be fully drained. Even one full discharge can cripple or ruin entirely your helicopter's battery.

batterys turn off when not flying
should charge when plugged into toy
green light is fully charged /on

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.

try this,switch the helicopter on,then make sure the left controller stick is fully down then turn the controller on,move left stick fully on then fully off should be ready to fly,have fun

1) Ensure you're fully charging. Indicator light on charging unit should NOT get brighter at all when you unplug the helicopter. If it does, then plug helicopter back into charger until light stays the same when you unplug. Note: If you're charging with a usb charger and are using a laptop or the front side data port on your desktop, these may take several hours to fully charge as they are usb 2.0 and do not carry the full 5 volt dc charge. Use powered usb (3.0) on back of desktop, or get a usb/ac adapter. Normal charge time approximately 1 hour. Go by the light, though.
2) Don't run them dead. As soon as you can no longer maintain altitude, land and turn off helicopter. Fully discharging a Li/Po battery (particularly when it's new) will cripple it's ability to hold a charge, and can ruin them.

hope this helps
