so whats the final say on rx8 vs mmm...

[Arct1k]

I'd say they are both 8th scale ESC with great support from US vendors...

If your car is Black with Green or Yellow get a MMM if you like Red then get a Tekin...

If you want a sensored motor then get a Tekin.

Even failure rates reported by Castle or Tekin have many variables that are unaccounted for, so it's questionable to call that empirical data also, but it's the closest we'll get.

I think we need to make a distinction between failure and potential for injury. My point is that the MMM doesn't seem to only fail, it seems to do it in a rather dangerous (and thats the V3, I haven't even begun to look at the V1 and V2 disasters). Suppose there is even a 0.1% failure rate. Now out of the million say, Toyota Corollas made each year, if 0.1% caught alight, that means there are 1000 fireballs. I can tell you right now, there'd be a public outcry if 1000 Corollas blew up in a year, but with the MMM people seem to tolerate it and even justify it. That makes no sense to me. Perhaps people don't place as high a value on personal safety and the safety of those around them that I do. So many of these brushless "experts" are chiming in on "misuse" but it's for sale in RTR packages, and with that the assumption has to be clear that not many RTR runners are experts and the electronics should have some sort of tolerance as a result.

Tell me is this misuse?

RC clubs (at least around here) do not want potential fireballs, that's why we run hard cased lipos, and why IMO if an ESC is proven to be susceptable to combustion in the event of a failure, then banning the use of it is perfectly reasonable in the interests of safety. I am yet to see a picture of an RX8 burnt to a crisp.

Sorry but this is:

[What's_nitro?]

What are the chances CC would make a flame-retardant plastic case for the MMM? I'm not suggesting this as an excuse to make it seem like it's "OK" for them to fail, or as an insult to CC, but as a safety measure. A little poof of smoke/flame is fine, IMO, but it needs to be kept from propagating away from the source. Actually, I think all MFG's of larger ESC's should do this....

Both systems seem to be pretty good. They each have their own place and usage.
But, just from the limited experience I have had with Castle, I really hope to never have to deal with them ever again. And long waits for their turn around times with all kinds of excuses for it.
No thanks.
Just my humble opinion.

If continued failures aren't a problem, then turnaround times reduce as the number of warranty claims drop. A 3-4 week turnaround or whatever it is now sort of indicates a failure prone unit doesn't it? That's just rubbing salt in the wound of someone wanting to participate in a "fun" hobby, first having a fireball, then a 3-4 week wait for a replacement which could well fireball as well.

I'm sure there are other variables for the long turnaround time. Keep in mind that Castle have to supply both Traxxas and HPI.

To me, it's personal preference. I like Castle and have 4 combos. I also had to shipped back three of them after they failed because of the BEC. I haven't experience any fireballs and hoping it will never be. I just ordered 2 Tekin combos (1 each for buggy and truggy) and another ESC so we'll see how it performs.

I don't feel sorry for you but it seems that your personal experience put a sour taste on your mouth. I had to wait longer because I am stationed overseas with the Navy. At least, you can get your packages overnight if need be.

No matter what, I'm going to continue supporting them because of their support for us in the military.

Actually the turnaround time to Australia is brutal. So it's probably still quicker for you than for me.

Well then, I feel sorry for you . Anyway, what city in OZ? We'll be going to Brisbane in a few months.

Other end of the country mate, I'm near Perth.

Want to know what we deal with (cost wise?) check this out:

They are what, $49.95 in the USA now?

Current exch rate is $1 AUD = $0.90 USD

mine was 53us from ny to sa in 8 days most hobby shops in aus couldn't have got it to me in that time frame never mind double price tag

Perth is a nice city. I was there (for the 2nd time) from July2-6 last year when our ship was anchored off the coast in Fremantle.

I didn't have a chance to go to the track but we had fun riding the bus that takes people around the city .
