Mmm V2 Up In Smoke !!!

[killajb]

Ahem.. With all due respect to Novak, how many HV ESC systems are on back-order? I assume the "Orange Guys" are in the business of selling products to make a profit. That said, the starting gun has already sounded and Castle (with MM and MMM) is off to a great head-start. ROAR can have their "rules" or as I see it, tricky attempts to corner the market through sanctioned races. The only ROAR I care about is the roar my REVO tires will sound like on occasional speed runs.

I have no doubt that the little TCs have no issues or shortage of power with the current ROAR approved motors, but thats not the issue so much so far as matters to me- I desire a powerful BL motor and esc system for an MT, not a TC. Im sure the green guys would like to be able to compete with the orange guys at all levels, but thats not the issue that concerns me- its the basher sector that baddly needs more attention. The only 'systems' for MT users at present are the hvmaxx, and the MMM combo, and I know which has the kind of power and performance Im after (flaming deaths not withstanding ). When the Tekin RX8 finally gets here both the green and orange guys will be in for a shock Im sure, but thats a good thing- motivation to compete at the same level for the same potential customers who just want a damned reliable esc and motor that can pull some kind of gearing in an MT with cooking or running out of puff after 30feet. I have the $ to spend if I must, but if a reliable, powerful esc atleast isnt in the offing, I'll end up running a pair of flippin' MMs and building a cursed V-twin type contraption to find the reliabilty and power I want. Gah....

I think this ROAR thing should be taken to NOVAK forum. This thread has been way OT. Just a suggestion.

Let's give Larry some room so he can get CC to assist him on his concern. just my opinion.

[TexasSP]

Patrick is dealing with Larry directly, there is nothing more for him to get out of this thread. So what does it matter if other things are talked about? This is a public forum.

[TruckBasher]

So it wont matter if all the thread gets out of topic then. Funny you should say that cause you always complain thing gets out of hand...no prob with me...just saying that we should keep thing in check....

If this is directed toward me, I am lost as to what you are talking about. I post in threads all the time that go way off original topic, and could care less.

Dunno about paragraph 1, but your "update" sounds like the BEC in the MMM is toast and the only way it will work is to externally back-feed 6v into the MMM. When you do this, does the rx pack/regulator get hot, and/or does the BEC circuit on the MMM get hot (you'll have to take it out of the case)? Depending on the MMM BEC circuit design, putting a voltage into its output can cause lots of heat. To me it sounds like your MMM evolved into a form of Opto-ESC.

I would send it back since that is obviously not how it is supposed to work. Good luck and let us know how it turns out.

Thanks for the thoughts and ideas. It will be late tomorrow before I can check rx pack and regulator. Do you have a tip on identifing the BEC circuit in the MMM? I'll report back when I test it.
Thanks

Well, when you take the MMM out of the case, the BEC circuit is directly on the bottom.

Thanks, I'll put it up on it's stand, pop the top of the MMM and run it for a while and check the temp on both the rx back and the BEC circuit.
Thanks Again

what physically causes them to fail? a connection break on the BEC?

I see no crimping of any wires so I don't think it is a connection break... just my thoughts. I've got a real delima ... I know the MMM is not working as it is suppose to but it is working (I'll find out tomorrow if it is causing overheating of the RX and/or BEC circuit). I leave for an out-of-town race two weeks from tomorrow. Do I send the MMM back to castle and hope to get a replacement before I leave or if it doesn't cause an overheating on the rx pack or BEC circuit do I use it for the race in two weeks and send it in afterwards. hmmmmmmmmmmmmm

[BrianG]

Dunno. That's a question for Patrick. I have a suspicion, but that's it.

Patrick, if you are out there can you weigh in on this? I realize Castle has a lot on their plate getting the new MMM v2s out; however if I overnight my MMM (this is my 1st v2 after receiving 2 v1s) to Castle is it possible they could return it (or another) in a few days? Feel free to PM or email me.
Thanks

If i were you i would try to email Patrick directly as he might not be on here for another week . Or try calling CC directly
