Looking for a motor!!! - Page 2 - RC-Monster Forums

E-Revonut · 08.20.2008, 04:45 PM

OK I have the choice of ordering a 9xl to hold me over until the cc/neu motors come out or go straight for a Tekno neu 1515 2.5d. Azjc thinks the power on 4S of the 2.5d would be disappointing though. I'm thinking that a little less power might be a good thing so that it would be a little more managable. If the neu motors are the quality and strength they have the reputation for I would hope it could pull 54/20-54/22 gearing which would give me the speed I'm after. Otherwise it's a 9xl with 62/20 gearing to get my speed, until I can get a cc 1515 1y. Thoughts?

A 1515 2.5DF on 4s is still a very powerful motor and will gear up very well...

Thanks for the input Arct1k, looks like I will be placing an order tonight!

I spoke with the guy at impaktrc and he recommended a 1512 2.5d for my e-revo 4s setup. Received it today and took it for a blast tonight.

Temp didn't break 140 on the motor after driving for 30 min straight. I'm using a mm with ccbec. I tried a 19t and a 21t. The temp difference was 7 degrees. I cannot believe this motor compaired to my 8xl. I like 21t MUCH better. It was much more driveable on the track.

Glad your happy with your 1512 2.5d but I'm going for the 1515 2.5d. The 1512 is a little smaller than the 1515 and not available in the form of a Tekno neu. Also the 1512 is a little higher kv at 2050 vs 1700. The 1512 is pretty close to an 8xl kv wise but a far superior motor, hope you also have an endbell cover to keep the dirt out of your investment. I wanted the Tekno neu because it is sealel and designed for land use, I did order the 1515 2.5d though, going to gear it 54/20 for now as I already have those gears and if temps are ok I step the pinion up a few teeth if I want some more speed.

did you get anything yet? i have a hacker i've been trying to get rid of? its really a better 6cell motor, but i ran 4cells with it in my lsp and it did pretty well.

Ordered a tekno neu wed night. 1515 2.5d

I may order one too for my erevo, and leave the 1512 for my hyper.

ordered it on Wed, received it today! Can't wait to get home tonight and do some soldering!

On first impressions, this is one hell of a motor!!! The thing is huge, makes the titans look like the rx280 out of my mini late-model and even dwarfs an 8xl! fit in finish is top notch (had better be for the $). Looking forward to enjoying my new setup! MMM, 1515 2.5d, 4S 6A lipo, dx3r/sr3100 = fun

sounds nice ..anxious to hear how you like it

Well I ran a pack through the monsters today(MMM/1515 2.5d/f) and I'm pretty happy with it so far. Waiting on my 25t pinion from Mike so I can really see what this setup can do. Running 54/20 currently and I have to hold it WOT pretty much all the time, only geared for about 33MPH, when I get that pinion I'll have options to go from 33-43MPH as long as temps allow me. I ran for 15 minutes in tall grass, no cooling holes in body, and no extra fans. I had 157* on the motor, 121* on the MMM, and 125* on Lipos. I'm hoping I can gear this up a little more and not increase motor temp much, with higher gearing I won't be full throttle so much. The fan never had to run on the MMM and it everything was super smooth. After a minute or two of running I found that it will still hang big wheelies. This setup is much smoother than the V1 MMM/8xl that I had ran in it 2 months ago. Only complaint with the v2MMM is the switch, if there's going to be a switch I think it should have a spot to mount it on the esc, I may wind up just gluing it on there.

rootar · 08.23.2008, 03:49 PM

actually when you gear up the motor temps will go down (to a point) but the esc temp will rise, id keep an eye on thoose lipos you dont wanna see more than 130 or things could go bad.

E-Revonut · 08.23.2008, 05:09 PM

ESC temp going up a little wouldn't be horrible, 120* is barely warm. As for the LiPos, I'm starting to understand the poor quality of MA cells, but also krepin mind that the E-REVO has sealed battery compartments for the most part

E-Revonut · **Further review of Tekno Neu 1515 2.5f/f on 4s -** 08.31.2008, 12:03 AM

I have ran several packs so far and I'm very pleased! I still have to change the gearing, I did finally get the gear from Mike, just haven't put it in yet. Wheelies on command from a stand still, even flips over without wheelie bar. From a slow roll it will still do the same, this is with my puch control turned up to 80%!!! I have to say I think this motor is morte than adequate and def not dissappointing on 4s, I can't imagine it on 5-6s. I will post more when I re-gear it.
