General need help with a co axial helicopter

[concept30]

Hey have there been anyone that bought a helicopter like this, the heli battery and radio are fine charges to 15 volts, but it still doesnt fly no more the a foot off the ground, what could be wrong?

Cant think why it would not go higher? I had one that was big, but was uncontrollable in any wind, even the slightest breeze

yeap, 2 mph winds and nothing you do can keep the wind from crashing it, my step dad had it a full stick and the the heli just flys a foot off the ground we change the bettery in the TX and charged the onboard heli battery to 15 volts

I flew mine at dusk once with no wind and it did everything I wanted Must of crashed it 100,s of times. Bought a Align 450 and never looked back

shoot i bought a blade 450 and i never flew it, spent 2 years adjusting the radio and the heli, im just trying to help my step dad to figure out what is wrong wtih his co axael.

The battery may well charge to full, but it may not be able to deliver the current needed anymore. I have a couple like that. Don't know if they got over discharged or what, but they work for maybe a minute and then flag and can basically hover only. Also, these coax models usually have brushed motors which can go bad in a short while. If it is worth it to you, see if you can get a battery replacment and be sure not to fly it until it drop to the ground. If that doesn't fix it, see about getting a replacement main motors.

Thanks, is there a bushless motor for this type of helicopter?

Even if there is, you'd need to get a brushless pair of brushless speed controllers for it too. I doubt it would make economic sense to bother. You could probably replace the whole thing for less. Brushed motor replacemets will be the way to go.
