RX8 or MMM combo?

I ended up finding some decent deals on some Neus but they were usually crimped end bells, or open to debris, or both.

Non sealed:


This one looks like non-screw captured:


The Tekin system is expensive, no question about it. But at least they're offering a true 6s solution with their combos. If you want a properly rated KV motor for 6s with the MMM you either get a Medusa (non sealed, pressed endbell) or buck up for a real Neu which makes it even more expensive than the Tekin combo.

Original Neus are open because they where designed for heli, airplane, and marine applications where dirt isn't present. A couple pieces of aluminum foil tape takes care of this, just as I have done on my Medusas. As for crimped ends, I have no idea where your getting that from because that pic doesn't show the back. The front is part of the can itself and I assure you that the back is not crimped/pressed/glued on, it is a Neu and it is screwed on. I do agree though that it is great that Tekin has multiple motor choices. I would have bought one if they where out a month ago.

Well, I was under the impression that the smooth can 1515s that offshore electrics had weren't screw captured. But if I'm wrong, I'm wrong. The open-ness of the motor isn't a huge deal since you can just tape it, I had planned on doing that if I got a Neu.

But then I figured, if I'm going to pay $400 for the MMM + a Neu motor then I might as well just get the Tekin system and try it out.

So am I to understand that you have actually tried the 2200 CC motor yourself and this is from your personal experience?

Or is this just what you heard?

Based on what I have seen Patrick say the motor was set to be what is the most efficient setup and you change the voltage and/or programming to suit your needs.

I would really like to see proof of this as I have never seen nor heard of it. It's a rather bold claim without anything to back it up.

my old 1.5d had no screws in the back end, ive seen a couple others also that popped off, so they just drilled holes and put screws in

castle combo

By all means, get the Tekin and try it out! Post your findings too. I just wanted to make sure you where aware that Neus are first class motors and anyone that has broke one was either beating the snot out of it or they F'ed something up, chances of a Neu going up in smoke due to manufacturing defect is very small. Tekin hasn't proved themselves in the 1/8th motor market yet, not saying anything bad about them but they still need to get put through their paces by the members here!

Oh, I have the utmost confidence in the Neu product and I'd love to own one. And the MMMv3 seems pretty solid as well. The Tekin seemed like a pretty solid and complete product and the initial positive reviews sold me on it. I just feel like comparing the cost of the Tekin combo to the MMM combo is a little unfair if you plan on running 6s. Unless you're cool with running the motor at 55,000 RPM.

And no, I don't own the MMM with the 2200kv motor. It looks really great, and if Castle had the 1800KV ready I would have bought that combo. But I feel that 2200kv is not ideal at 6s. I came to that conclusion from reading the forums and playing with BrianG's gearing calc. Do you run the 2200 at 6s TexasSP?

No, I run I tekno neu 2.5d. It was what was available at the time. I have also used a 2200 neu. I have come to the conclusion though that the 2200 motor on a monster truck is the one to have if running 4-6s. I have enough confidence in the CC software that I can run different setups via programming to utilize the motor correctly for what I need.

I am in no way dogging the Tekin, I just do not agree with it's all of the sudden God status over all else. It seems to me like the attitude coming from some is that the only way to be competitive is to run the Tekin and if you come running the MMM you will just get beat.

The same thing can be said for when the MMM came out and people thought you had to have it over the MGM or you were screwed.

I hear what you're saying, but 2200kv at 6s is 55,000 RPM and leaves me little room for gearing options. No amount of software tweaking is going to change that.

Let me say that I don't intend on racing and don't have a track within 30 miles. I only bash. I think the MMM has to be a good system otherwise they wouldn't be shipping with HPI and Traxxas products. My only gripe was the lack of motor selection. And my justification for buying the Tekin system was that I was going to spend $400 anyway on a MMM/Neu so I might as well try something new.

what we truely need to do is mask-up both system and put then in the same buggy (unmarked) and have people drive it around for bashing and racing..and do a variety of combonations....ie MMM/tekin.....MMM/Neu.....MMM/CC Neu.....rx8/CC NEU....rx8/Neu.....rx8/tekin....MMM/CC Neu...of course all the same gearing/batt's/esc setup and truck setup....thats the only way but I for one like both combos however, i'm waiting for CC's 1800kv motor....but I've never had any cogging in my MMM setup and ALCEDAMA the 2200kv cc Nue motor works just as efficiently as a genuine NEU (I've own both in 2200kv form) and I really couldn't tell the difference IMOH...

When did I question the quality/efficiency of the CC/Neu?. This is getting frustrating, I'm saying (over and over) that 2200kv is A LOT OF KV FOR 6S LIPO.

There's a reason why Tekin is offering a range of KV choices that ranges from 1350kv. It's for people who want to run 6s lipo.

Hell, using BrianG's calc the only way I'd get the 2200 motor down to 40mph on 6s in my MBX5T is with the RCM 9t pinion (smallest pinion available) and I don't know if that would even fit.

I get what your saying but look at it this way.

My FLM stampede I had geared for 60 mph running the MM. However, when not doing speed runs and/or letting other people use it this was unrealistic. So my solution is that I had different saved profiles for what I was doing.

I would lower the throttle curve to only allow full power just towards the end of the curve. I would also reduce start power and adjust the punch control. It was very easy for me to control my finger from neutral to 3/4 throttle at which point the truck would only do about 30. If I wanted more there was that last point I could get between 3/4 and full. The same can be done with the MMM and 2200 motor. Gear for 50-55, then adjust the software according to your needs.

To me it's just another way of looking at and solving the problem, not the only way. Some can do it by KV, some by voltage, and some by software, yet others by a combination of the 3. I just pointing out that there are other ways. Whatever way you choose is fine, just don't forget that may not be the only answer.

cheack out the 2.5d on this car.. no screws

I think I will be trying out an RX8 in my 1/8th buggy when I get it...you guys will see build up pics probably in about 5-6 months Im broke so I gotta take my time

[TexasSP]

You have thoroughly proven my point. Your claims are nothing more than opinion with no fact to prove them. Data logging is the only way you can prove one motor is as, more, or less efficient than any other. Anything else is speculation and nothing more.

Also make note that nowhere in this thread have I asked for anyone's opinion.
