Hi guys, I'm hoping you can point me in the right direction with a problem I'm having.
I bought some new 11.1v 3s2p lipo packs for my MX400 heli.
One of which is not working and for the life of me I can't figure it out.
The pack took a first charge of 1500mah which seems pretty normal considering most packs come more than half charged already.
Charged voltage was a little over 12.4V.
When I went to use it in the heli it powers uo ok and all servo's & gyro etc work but the motor won't spin past 2-300 rpm.
It's like the pack is dead and the lipo saftey cut off is kicking in.
I also though that the pack could be a dud and not able to supply enough amps to run the motor above quarter throttle.
I disengaged the motor to see if it would spin up whilst not under load.
It powers up 100% no problem, weird eh?
When re-engaged the motor with the main gear the same problem occured, basically no throttle at all.

Am I missing something ?
Is there somehting I am supposed to do to new packs?

Any help you guys could offer would be warmly accepted.

Thanks!
Karl
