I'm flying a little indoor type profile foamy outside the house and have recently encountered some problems.
Axi motor, APC 8x4- 3 cell 500mAh packs.
One pack appears to perform well, blistering performance flying a pattern far larger than possible inside.
Change to the other packs, can't get full throttle, the motor just seems to go rich (yeap, I'm a glowhead!)
Both packs the same, fine up to 75% anything over, the engine (speed controller?) seems to cut back hard... the sound even changes.
It sounds rough in glow terms. all loaded up. If this was a glow I'd say it's because the prop load is to much for the motor.
What's this all about?

Could those packs be puting out a higher current/voltage or what ever the eTerm is thus causing the speed controller to miss-fire?
Why the different sound?

I'm in the office so I can't give you the motor/speed controller ID's.
Just wondering if somebody had come across this before and identified the cause/fix.
Cheers in advance.

PS. If I haven't posted this in the correct forum, feel free to repost.

Sounds like the other batteries aren't putting out the amps at full throttle.

That's where the C rating comes in. If the "hot" battery is higher C rated, or the other batteries were previously reviewed.

Either way, you're putting more of a load on the other packs than they are capable of delivering.

Sorry for the late reply.<div>All three batteries are rated at 25C. least that's what it says on the pack.</div><div>Yes, you saying it's to much load sounds right to my glow ears... but what does that eTerm actually mean?</div><div>Am I running the motor to hard, using a to big of prop?</div><div>
