RX8 or MMM combo?

I was talking about the crimped part. I have followed neu motors for several years via plane guys I know and have never seen one with a crimped can. The sealed part is just plain silly as the motors with the holes in them where not originally built for off road use. However, the Tekno neus and CC neus which are built for off road use are sealed so the point really seems moot.

I get these guys like their tekin systems, I like my tekin I use in my scale crawler. While they are nice ESC's I do not find them "way better" than what CC produces. Another thing about the size factor is that CC attached the capacitors to their ESC's from the factory and that is reflected in their size specs. However tekin requires that you attach the capacitor(s) yourself and thus does not factor that into their size specs. I also much prefer the bullet connectors to the solder posts hands down.

Again I would also like to see how smooth the tekin runs a completely sensorless motor. Or we can wait for the MM Pro and compare then......

It seems as nothing anyone tells you from their experience with both systems is going to matter. You obviously are 100% sold on the MMM. Like I said, if you are just bashing around with your MMM, it will serve you well. However, those of us that race have found the Tekin system to be better suited for the track.

I will be putting both my buggy & truggy through the paces on a a very large track this weekend ('09 ROAR Nats track) for a race and can report back more how it performs.

Regarding the efficiency comment, I compared my burn rate per minute with my Neu vs my Tekin and it is almost identical, even though the Tekin was laying down a little more power in my opinion.

You do not read well do you. I am not dogging the tekin system, only the arrogance behind the arguments. I also own a tekin controller and like it, so how does that make me 100% sold on CC period. I could have used a sidewinder or MM for my purposes.

Which prove nothing as far as efficiency goes. Get some data logging done then I will pay attention. What your saying is as ridiculous as the people on the Traxxas forums who claim their single VXL revo goes X mph just by looking at it.

All I am asking for is people to post up FACT to base their arguments and opinions on.

I also will say this again, putting a sensored system up against a sensorless system and comparing smoothness is apples to oranges. Seeing as the MMM will not run sensored, I would like to see reports of how the Tekin does running completely sensorless. Or like I said it can wait until the MM Pro comes out for a more fair comparison.

Lighten up Francis.

You ask for people's opinions on the system and then when people give you their opinions, you find some reason to challenge their opinions. Like I said, if you are happy with the MMM then by all means keep using it. It gets the job done. No one is putting the Tekin system on God like status, nor is anyone bashing the MMM. Different strokes for different folks. It ain't perfect, but based on owing both systems, I think the Tekin has upped the bar. If you feel differently, then keep running the MMM.

However, as someone who has owned about 7 MMM and 8 different Neu motors over the past year that I have used for racing, I think I am qualified to make a unbiased judgement on the performance of the systems in the real world. I lost count of the thousands I spend each year screwing around with different crap to see what works and doesn't. I don't mind giving my unbiased opinion as I have no horse in the race. It either works or it doesn't.

Do I have a data logger hooked up? Nope, but I don't think one is needed when I raced one weekend with a Neu 1515 2.5d/MMM in my Truggy and then race again the following weekend and the only thing that changes is the ESC/Motor - same exact track layout, same batteries, same car, same bad driving. Measuring what I took out of a full charged pack vs what I put back after a qualifier gives me a fairly accurate measure as to the efficiency of the system in the real world. Particularly when I do this over three timed qualifiers and and a main. I hardly think this is the same as a 13 year claiming thier VXL hit 80 with a 7 cell nimh pack.

Will the rx8 hold up to the season of racing? I don't know, but I am about to find out. However, given the performance after a weekend of racing the snot out of it, I am confident it will.
