getting pretty close to the purchase of my motor, and just want to make sure i,m getting what i should. I am looking at : 1515 1y (2200kv), 1515 2D (2050kv) and 1515 2.5 D (1650kv). I am currently leaning towards the 2d as it is somewhere in between. looking to run 4s now and 6s later if/when 4s gets too slow, that,s where i would see the 2.5 as being the better choice, but i dont know if it will perform as well on 4s. also i think the 1y wont like 6s too much, getting high on the rpm's. Just want to make sure that my $250 is gonna get me what i need.

I want an answer to this too, will gearing matter with the motors? was hopping to hit about 50 on 6s with the mmm
I was going to get the 1y but now i'm not sure if i can run 4s on it. would like to be able to run 4s for longer run time and bashing
this is for an erevo

I think you need to consider availability into your equation… I can’t find a decent 1515 can Neu or Teckno-Neu anywhere!!!

2.5 is very versatile - 4s it will gear up, 5s is perfect, 6s is insane...

It was my choice... If mike can't get you one there are places with them in stock.

I was actually thinking of building one from Nue's site, but if i could find one on here i wouldn't mind buying it either. Ive never bought one before so i'm not sure which way is better to go.

Would a 1515 1/y work good in a E Revo? I may be getting one sometime, and still have all my electronics to drop in. Also, what gearing would work well with the stock diffs if I don;t go to 1/8th right of way?

1y is good for 6s, 20-24t pinions / 58-68t spurs. 2.5d on 4s is a little faster than stock twins but w/ lots of torque, depending on gearing.

Yes the 1515/1y will work. I have that in my E Revo. On 6S with 62/22 gearing this Revo hit 61.7 mph GPSed 3 weeks ago.

I guess my question is what gearing with the stock e revo with 1515 1/y. Meanign, what pinion running 5s, or 4s?

I have my 2.5d geared for ~43mph on my erevo on 4s lipo and it does great.. 22/54 it's actually perfect for the race track, just right on the top end and explosive on the bottom.

TexasSP · 10.02.2008, 11:35 PM

I kind of doubt that at only 24k RPM's. On 6s with a 2.5d you're only good gearing up to about 50 and 45 is about right.

Still doesn't mean the motor can make it. I can put a micro motor on there and make it say I can drive it at 100 mph, it still won't happen.......

The calculator is simply a useful tool to aid you with a setup, it is not the end all be all.

JThiessen · 10.03.2008, 09:38 AM

I've asked this before, and only kinda got an answer - what RPM should we be shooting for on a Neu? Somewhere in the mid to low 30's is what I presumed. I'm slated to gear mine at 30/54 and run it on 6S - possibly 4S.

I've gps'ed it at 42 (41.6 actual).. lol that is what I was telling you. I said it did this speed you were the one arguing. The calc numbers were just to prove the point.
