NEU 1515 2.5D will be the best choice for your set up the Neu 1515 1Y is good for 4s lipo set up .

I've chosen the 1515 2.5d for 5s with a quark, in a truggy, but it won't be ready to run for a while.

I run the 1515 1/y with the Quark 125. It runs way cool! I have also ran it on 5s...it was pretty crazy! The batts on the 5s got a tad on the warm side, but not bad at all. The Quark and the motor were reasonable temps as ell on the 5s, but I get way better temps on the 4s, that is for sure. If you are getting 5s, then I would most likely suggest the 2.5 for your Neu selection then.

Thanks guys. Your knowledge in this area never ceases to amaze me. I am new to the whole semi-custom monster truck hobby and appreciate your advice.

I run the 1512/2.5D (2000kv) on 5s and it runs all day no issue. I started off with a 1515/2.5D on 5s in my Revo and wound up swithing to the 1512/2.5D. I like it better for the type of running I do most of the time. The grearing needed is a little different for the 2 motors, but I can run gearing that gets me another 5pmh without thermalling over what I could get with the 1515/2.5D. Plus, overall it has a snappier feel to me, which I like. The 1515/2.5D probably has a little more low end grunt, but it really cant be used unless you have a really heavy truck. I can spin the tires or flip the truck instantly (depending on traction conditions) with either motor so extra low end is kinda useless anyway.

If I put it on the track, I run a 4s setup and it tames it out a bit and makes it a little more driveable.

Just my $0.02. I'd vote for the 1512/2.5D.

Thanks for sharing.

Neu 1521-1Y
 

Has anybody ever heard of a Neu 1521-1Y (1577KV) motor?

You saw that on ebay too huh? It looks like a longer motor. If you have room to mount it you could probably make it work. It would have TONS of torque. You could probably get away with some pretty tall gearing on it. Heavy motor tough.

Yep...killer price too. I notice that Mike is out of the 1515 2.5D...I was hoping to order one this week.

wow those are great prices. makes it real tempting to order another motor. to bad I just ordered another feiago this weekend.

The only thing with the 1521 motors is that the motor mounting holes are 4mm instead of the normal 3mm. That was the only thing that stopped me from buying one...

Bye:018:

I think the motor below would be good for a "small" truck. :)

If you haven't already done so, check out the "shop pictures". Really shows what those motors are made of!

with a motor that heavy I would prefer the larger screws. I am really tempted to order it for my 8ight t. with that motor heat should never be an issue. I already have a 1512 (never used) waiting for the truck when ever mike finishes the motor mounts but am still tempted.

So, do you guys that motor will work in an 8ight truck? I need a good motor.

I am holding out for the NEU 1515 2.5D
