Neu motors

[coolhandcountry]

Well i got one myself to try. I got a 1512 2.5d. It kind of surprised me. It has good power and pretty smooth. I don't care for open design. I mussed steering linkage so couldn't finish testing. I think they are pretty good motors so far.

I thought the 1512's and 1515's are closed Leroy?

got a picture of her?

[coolhandcountry]

Not yet. It is open though. I think Mike is going to see if they make a closed in model. I try to get some later.

I must run my stuff harder than mike... I got my motors up to 200 degrees in testing yesterday at the track. That's after a very long run. After 5-10 minutes the temps are not bad... like 150-180 max. But eventually I got them hot. I ran at least 30 minutes with the truggy/1515... not sure exactly how long.

So I'm a little disapointed in that, but the motors still are awesome on runtime and they take a lot longer to heat up than my hacker or feigaos.

I have the cars geared for only about 30mph... not too high. That's about the same as mike's truck, and both trucks weigh about the same too.

I'm going to put a fan on them and see what happens. I think that will help a lot on a long run.

The biggest shock of the day was how great the Mamba Max worked. I don't think it ever hit 150 without a fan, and it temped like 120s with a small fan. I didn't check or record the mamba temps a lot cause it never got very hot so I wasn't concerned. Just surprised. :)

I think your truck might be a little under geared and thats why the motor was getting hot.

I ran my neu and it reached about 110 with 90 temps out side. I was
happy with it.

Yeah I need to do some experimenting.... I can say the runtime was AWESOME....

My buggy ran 15 minutes solid racing and used less than 4000mah according to the eagle tree and my charger... about 3800 or so...

Oh... I think the MM might have temped over 160 once... I didn't write stuff down. Anyway, it was more than cool enough.

@glass;

do you use the mamba maxx on 4S?

[glassdoctor]

yep... with a ubec

[neweuser]

Wow. These motors sound great. Doctor-do you hit the brakes a lot on the track? If so, that might be a concern. It puts a lot on the motor!!!! FYI. The more you use the brakes, the more it's gonna heat up.

Glass, does the mamba maxx supports a 4S cut-off?

[MetalMan]

It does. You can choose custom cutoff voltage or 12v, and I think even auto Lipo cutoff.

Sounds like a nice controller then.. perhaps i need to try one on my XL2400, on 4S..

I guess you remove the red wire from the esc to the receiver, right?

If you use a UBEC, yes.

that was what I was talking about.

thanks.
