View Full Version : Battery Problem

Why does my battery only last 1 minute flight time (only hovering) ?
Is everyone else the same?

The only batter problem I get is that the battery keeps falling out!!!!!!!!!!!

I'm so upset coz all three batteries died after around 10 cycles.....
now I dont even get 1 minute of flight out of those packs

That's bad. Is your charger working properly?
12-26-2008, 12:07 PM
I've got a 4g3 comming in the mail so not sure yet if they have a low battery cut-off..
If they don't - did you maybe run the batteries too low ?

Tell you,what J-S, get a load of spare blades!!!!!!!!!! My batt falling out totalled 2 pairs of blades!!!!!!!!!
12-26-2008, 12:35 PM
I dont think I did coz I never got more then 2 minutes out of the packs......
maybe I got 3 bad packs to start with
is there a cable for converting 2s to 1s so I can charge with a proper charger instead of that rubblish charger !!??

I've bought 2 new 600mah packs but still getting the same problem
it lift off for 4 seconds and then falls down as if the battery is flat and then once I power down I can power up again and repeat the same thing
whats going on.....

check if you have hair wrapped in the main and tail blades
12-27-2008, 08:57 AM
yep I've checked both blades are clean

Have you ever over-discharge the batteries before?
I broke in the batteries for the first three flight - meaning gentle flight without sudden throttle change for three minutes before recharging. Now, I have the batteries last for 5.5 minutes even on idle up and around 15 recharging cycles already without issues. I like the break in the batteries when new as I always did that with the bigger batteries in bigger birds. And, making sure no over-discharge too.

I'm pretty sure I didnt overdischarge coz I've tried putting new batteries on but getting the same thing
I dont know what to do......tried to take everything apart and rebuild but still not helping, I really liked this heli....I dont want it to became a static model......

Could well be the main motor dying. I still haven't flown my 4G3 enough to kill the motor, though they are similar to 4#3A/B main motors and they don't last that long. Most problems folk have with flight times and power are down to the motor. Although the motors are called 'brushed' motors, there are no brushes in them, only fragile metal fingers that contact the commutator and hence wear down relatively quickly.
I've had some of the 400mAh batteries since January and they still work ok, the only thing is try not to bend the wires too much as they are brittle inside.

problem solved at last !!!!!!
Its all about tx settings.....I took it to LHS and they helpped me fixed it but it takes almost full stick to hover, is that normal?
12-29-2008, 07:35 AM
Certainly not. Should be lifting just over mid-stick. I have tweaked the throttle curve to give greater rpm , and mine lifts at approx 60% stick. Still doesn't sound as if you are getting all the volts to the motor. Have you checked the blade pitch settings? Zero at mid-stick/idle up etc?

I have no idea...can u plz give me ur best configuation for the tx? thank you

All my settings are as per out of the box, excepting an upping of the NORM throttle curve - just followed the instructions for doing that in the manual. Like all these helis, you need to set the blade pitch to zero at mid-stick, in STUNT or IDLE UP mode. Might be worth a check, but make sure you disconnect the motor first!!

I've just posted some settings and a link to some more in a new thread. It sounds like the shop has dialed out much of the pitch, since it's always when the throttle is punched that the heli yaws, if it doesn't have the pitch available it will be a lot smoother since you are already close to full throttle, but you'll struggle outdoors when you want the extra power.
