help can any one help me re my e sky heli when i plug a charged battery pack in nothing happens only the light on the giro flash red then green

BEFORE you plug in the flight battery, make sure Tx is on, crystals are sitting properly, and throttle at minimum and perhaps center all trims. Make sure the switches on the Tx are on the right position. Don't have my Tx at work here but IIRC 2 on the left are on lower position and the 2 on the right are on upper position. Also, on mine the throttle trim has to be about 5 notches below center at startup or the Rx LED would stay red. The Rx takes some reading at startup so all of the above has to be done BEFORE plugging in the flight battery. In normal startup procedures, the LED should flash red perhaps twice first. If the Tx is "talking" to the Rx properly, the Rx LED should flash green 3 to 4 times initiating the gyro. After that, the LED should stay green. All the while, leave the heli on flat ground and do NOT move it or any Tx controls. Any time you adjust the mixer proportional trim on the Rx, you have to disconnect and reconnect to make it effective. Other than that, it might be a genuine problem.

You must have the throttle and the throttle trim at there lowest settings (all of the way down), and the transmitter on before plugging in the helicopter battery. Then wait for all flashing to stop, and the light to go solid green. Now you should be able to throttle up.

hi thanks for you replies i have tryed as you suggested but it still doesn,t do anything and the lights still keep flashing red and green please help befor i go mad and jump up and down on it.[>:]

Can you be more specific? Flashing red THEN green is normal startup procedure. Flashing between red and green all the time is a different matter and suggests something is wrong. I get this when my throttle trim is barely low enough and fluctuates between OK and not OK. I also get this when I don't fully extend my Tx antenna and reception was bad with all sorts of interference. But then in that case, the servos would jitter and I'd know what I did wrong. So questions for you:
- do the servos jitter?
- do the servos respond to your Tx input?
- do the flashing (or at least its flashing rate) change when you change throttle input?
- does it ever flash green 3 times (about 1 flash per second, no red in between)?
If none of the above, your Tx/Rx are not even talking.
Unplug the motors. Try again and then try switching OFF the Tx. Make sure the motors are not plugged in. Anything changes?

thanks for your reply
no the servos dont chatter or responed to any input from tx
the lights only flash red and green constantly they never flash just green or stay green
i have tryed it with the aerial fully exstended no change
and i tryed unpluging the motors and turning it off still no change
no response at all just the light flashing red and green

Then your Tx and Rx are not communicating. Are those all stock components? Make sure both crystals sit in properly. Otherwise, I have no clue. Try another Tx if possible. All I can say from my experience with the esky radio is that if signal is intermittent, Rx flashes very quickly and kind of randomly between red and green. If Rx doesn't get signal at all, it'll flash red a few times and then stay red afterwards.

hi yes all parts are stock bits, i have tried a diferant tx, cristals seem to be in ok, if i plug the battery in to the receiver instead of the plug, the servos work but no motors

has any one got any idears please

If gyro/mixer keeps flashing between red and green even after you switched off Tx (motor unplugged to avoid unintentional motion), then your Rx/gyro/mixer probably finds a fault at initialization and comes to a halt at that stage. Whenever working properly but doesn't receive signal (like turning off Tx), the Rx/gyro/mixer LED should stay red solid. If you don't have another set of Rx/gyro/mixer for diagnostics, I would suggest getting the shop you bought the heli from to do more diagnostics if possible. Otherwise, I can only suggest trying anything that "might" make that flashing red/green go away. For example, unplug all servos and motors and try again. Or unplug the Rx crystal and try again (not sure if that's a bad thing for the electronics though). Or if you have the later "separable" Rx/gyro/mixer box, unplug the gyro/mixer connectors (channel 3/4) to the Rx. Have you ever unplugged the servos and/or gyro/mixer connectors and accidentally plugged them backwards?

did you try to check the cristals,

if they both have the same frequency

i have the E-sky v1 and the E-sky 3D ... and i use both cristals in 1 transmitter its easy to change them
sometimes i use the 4 channel for both heli`s or the 6 for both .. i have changed mine from 35MHZ and to 72MHZ .. without any problems

there is always a lable on it with the frequentie of the cristals

This may sound silly, but is your board plugged into the right slot in the receiver?
