Cogging when Full power?

[Serum]

What LVC did you used Troy?

[neweuser]

It was the MM esc. But it also did it with my HV when I had 3800 IB's. Same exact thing.
I did also run the 12020 with a LVC that was not the opto mode and it did it with that as well. When I removed the LVC it seemed better, but still stuttered a bit.

Need to read what I write! Working on two forums here! lol same issues.

But Serum is right, I would contact Austin, who is a great guy.

Another thing to consider, the HV4400 was lower powered, so it needs current to run hard, thats going to play havoc with all but the best LIPO's. I run NIMH on mine (12 cells) and they would come off so hot i would not be able to charge them for at least an hour, because they needed that much time to cool down

It could also be poor solder joints as well? Have you checked all solder points for quality bond? Lengthy wires might be the culprit too, who knows?

Hi again

Thanks for all the replys.

I know I should have got the 8000mah. in the first place, but I am still not sure that it is the problem. When I take of the lisaver, there is no problems at all. It just flies away, with no "cogging".

When I am finished driving the lipos are hardly warm, but the motor is for sure.

Could this be a motor issue. Would it help me to replace the rotor with the HV 6,5 rotor (the cheap solution), or should I upgrade to a senserless system?

Best regards
Jesper

If you are using the old non sintered rotor an upgrade might be wise. the new rotor doen't make your motor spin at lower rpm, but it makes it more efficient on partial load.

You can use the new sintered rotor in the old 4400 motor.

[Klausen]

Ok, I will try that. Thanks for the reply.

[Serum]

Yeah, anytime. I heard the new rotor works miracles.

It does lower the kv of tth motor, on Novacks site they are now rated at 3100kv

[zeropointbug]

THey seriously need a ~2000kv motor, that would open their market. Better yet, a larger rotor.

[Serum]

a two pole rotor doesn't change the kv. the amount of windings in the can (which isn't replaced) does change the kv.

i think they have got an unloaded and loaded value mixed up.

[Serum]

A larger rotor, that's something i would aim for. they use small rotors and high kv, and we all know what results that leads to.

[crazyjr]

The power of the rotor will change it, the 5800's have gone down to about 5000 now with the sintered rotor. I would think the strength of the rotor would effect the KV

[Serum]

If it's an unloaded value it simple doesn't.

[zeropointbug]

I wonder how a sintered rotor compares to a slotted/laminated rotor. But the Neu has larger gaps in the rotor between poles, maybe for good reason?
