death motor!!!!or not??
 

i run today my e-maxx and after 10min of hard acceleration and braking in the street,,,the truck look like loose brake...or something else..and the motor start to cogging...i check with my gun temp and the motor was 290F:gasp:(feigao 6xl)my esc (mmm)90f and the pack(lipo maxamp 8000hv 7,4x2) 101f......no power come out of the motor and no brake.....it is burn????i try another motor and no issue at all and the esc run flawlessly....i was scared i was tinking that my mmm was died:yes:

maybe you demagnetized the rotor from excess heat
open motor an check rotor for magnetism

yes i did this....and :yes:the rotor is very lightly magnetized,,,, its complytely out of buisness:lol:

that just gives you a reason to get a better motor :D

i waithing for my neu 1515 1,5d f:mdr:i have a 1515 1y but not enought kv for my 4 cell set-up:yes:

You can't expect much more from a 6xl though... those things will run hot as hell... :lol: Why isn't the 1515/1y enough Kv for you? You can easily reach 45mph on 4s with it...

Yes it can! I run a 1515 1y on 4s in a jammin crt and it radared at 46mph. I have it on video too... I cant really see why you would want more. Maybe for bashing...

Bye:mdr:

im geared 20/68 and ive got a run time of 15min max at 34mph(calculed with r/c calculation)with a pair of 5000mah 25c neuenergy...if i go up like 22/68 i could get more speed but the courant draw is more significant....no???

If you gear a 1515 1y on 4s for the same speed as a 6xl on 4s, then the neu should have a bit more runtime and less heat.

right....my top speed is lower with my 1515 1y vs the 6xl but wowo:surprised:the max temp that i reach is 114f(compared to my death feigao 6xl 290f) for 20 min of street bashing....

you have a 1515/1 and a MMM I would go up to a 5s pack and if that is not enough you could go to 6s...you can wire a 3s pack that is idenical to one of your 2s packs in series to form a 5s pack..."You need more power"...when you go higher kv the motor becomes more amp hungry and that will cause heat

your right....i never think about plug one 11,1 volt with a 7,4......i never think that it was possible:yes:you give me a good solution!!!:rules:

just make sure it is the same capacity, and I would go with the same brand since your chances that they would be the same cells would be better

this is what i tinking:yes:but now i have a 1515 1,5d to come...can i run this motor on 5cell ??? or keep 4 cell...i would 45mph im geared 20/68...

I think 4s will be plenty for a 1.5d but it will eat more amps causing more heat, be sure your timing for the ESC is at the lowest setting, and I went back looking at your first post and it looks like the truck you have is an E Revo if it is the biggest 8000 size you could fit in the compartment would be a 2s
