Cogging? LRP Sphere 007 + 6,5t

[dewil]

Hello guys!
I recently bought a Lrp sphere 007 with an Lrp 6,5t motor to use in my Lazer ZX-5. I have noticed that it hesitates a little when giving full throttle from a stand still and a guy at the club said it was cogging.

How can that be? it is geared 17 / 78 wich should be pretty low and I use standard settings and a team orion carbon lipo battery.

Is my gearing too high or is something wrong with my system or settings?

Really would epreciate any help.
Best regards

Are you using ko radio with spektrum? I had this problem until i put the big spektrum cap on.

noop, not using spectrum. just an ordniary fm 40 mhz hitec lynx 3d. There are however no glitches or anything, just that cogging when taking off.

Check your sensor lead.

When I forgot to plug in my sensor lead it wouldn't run at all.

cogging in a brushless system is caused mainly in 2 ways.

1 is as posted a sudden drop in power in when you give the gas, this from what i can gather happens more with lipos than nimh`s.

the other cause is when a sensor wire is old they seem to be less tolerante to heat than when new so when the motor is warm not hot then you give beans from the line it sees loads of power that it thinks might cause it damage so it hesitates or cogs

a new lead will sort the problem i would also check the winds in side to make sure they havnt got to hot and the laquer started to burn off.

i hope that helps i too have had a coging motor which was solved with a new sensor wire i think they start to blacken inside causing resistance which causes the problem.

its more to do with the voltage dropping on any pack not just lipo, a good lipo pack will be ok, my problem was not with my trakpower lipo but with some NIMH cells

Mark C you were absolutely right. I tried taking it off the lipo-mode and now it runs super-smooth. Thanks for the help everyone!

Hi guys,
thought i would post my question here rather than start a new thread.

I have a Sphere TC, and have been running an orion 13.5t for a few weeks without any problems. I decided to try a 'cheap' lrp eraser 10.5t to see how it went, and I had terrible cogging out of the slower corners.
It is running in nimh racing mode and is using the same sensor wire as with the orion. In the end i had to switch back to the orion, and all was fine.

Anyone any ideas?

Thanks

Ross

No one ?

I had a friend try this motor with a nosram matrix, and again had that same cogging problem. I also spoke to another competitor and he had the exact same problem with the nosram Dragon motor. Seems like the sport lrp/nosram motors dont like working with the competition speedo's

Thanks

Ross
