you'll have to get in line behind me! ;)

Sylvester 01.09.2007 09:19 PM

If its a fight you want, than its a fight you get!

Ill be waiting in front of castles doorstep so i can get it first! MUhahah ;) :p

Only if it was that easy!

crazyjr 01.09.2007 09:30 PM

So the race is on;)

Sylvester 01.09.2007 09:39 PM

Dont even try, i got a Buggati Veyron waiting at the airport and while its waiting ill be in my private jet flying to the U.S. Hehe, i bet its THAT easy for some billionaires ;)

BrianG 01.09.2007 10:36 PM

Yeah, I really like that heatsink. Looks like there's metal going in between the PCBs to cool the FETs in between the layers. The whole thing is a little bigger but I definitely don't mind.

And whoever is first in line for the MMM, can you just pick up an extra one for me since I don't want to be one of those fools who are going to be camping outside to be the first to get one. :)

All I can say is "The Brain" Strikes Again! Thats the smart way to handle it! LOL :dft012:

crazyjr 01.09.2007 11:16 PM

Actually Jhautz is probably closer than me, he has a connection and probably a beta tester. I'll get on the mailing list to get mine, Camping sux

isn't it funny how threads get hijacked here

Lol, it was just common sense! No use in two people sleeping outside when I can be comfy in my house. :)

BrianG 01.09.2007 11:30 PM

Speaking of the MMM, has anyone noticed that the link to the MMM is missing from the products page? I got a little excited there for a second, but found you can still type the address to get there directly though and there's no change. :(

crazyjr 01.09.2007 11:34 PM

I heard they pulled it from the main page to quiet the people that are bugging them for it now. Personally i'd just like the esc, there are plenty of excellent motor out there, Not sure how castle can add to it at the similar priceline that the mamba max motors did

gixxer 01.10.2007 12:15 AM

totally agree, I dont care what motors they come out with. I just want the esc and soon. A real time frame would be nice but it doesn't look like we are going to get one.

Me too :). I was a beta tester for the Mamba Max as well :004:.

I have no connections... I just like to call and ask alot of questions. Its amazing what you can find out when you ask in the right way. Tell them about a problem your having and make some sugestions about how they could improve their product. next thing you know they are telling you what ''might'' be in the works for the next gen of products.

I was not a beta tester for MM and am not on the list for the MMM. By the time I asked, the list was already full.

But you better believe I'll be paying attenetion when we start hearing about the beta test units going out.

crazyjr 01.10.2007 01:17 AM

I'm sorry, I got you and Glassdoctor mixed up. I thought you were the one building the truggy for them to test with

my bad

jhautz 01.10.2007 01:24 AM

No worries... I would if I had the chance...:018:

Procharged5.0 01.10.2007 01:57 PM

I'm on the list & have been for about a year. Who knows who gets selected. But I'll keep my fingers crossed! For now I'll buy the MM and see where things go from there.

phildogg 01.10.2007 08:39 PM

list what list? I want ot be on the list also.. lol
phil

crazyjr 01.10.2007 09:01 PM

I think its for beta testers, too much like work for me

MetalMan 01.10.2007 11:10 PM

Yeah, it is a lot of work. Besides testing out numerous configurations, it also entails a detailed (long) report of your testing.

Typing and essay writing are not my strong points, If you look at some of my posts you will see that, not as bad as NBC but you get the point

BitHed 01.18.2007 12:03 AM

...so to get some grasp of this there is NO 100% ABSOLUTE fix for 'The Quirk'?

glassdoctor 01.18.2007 12:52 PM

I think he means the MM Quirk.. not the Quark, lol

No, there is not a 100% fix for any of the "quirks" discussed.

CC doesn't believe my quirk is more than an isolated case... basicly it's me and nobody else has the problem.

BrianG 01.18.2007 01:10 PM

I don't know about that GD; there have been quite a few people who have experienced one form of the quirk or another in this thread alone. But they may simply less concerned with it as it makes less difference in casual usage (bashing).

glassdoctor 01.20.2007 12:49 AM

BG, I know there is a couple different glitches in the MM.... but does CC see it that way?

The quirk that I have complained about when racing is different and much harder to "see" and repeat. I don't think CC has ever seen what I have seen.

At least as for "my" glitch, CC seems to be taking the position that it doesn't exist because only myself and my racing buggy have reported it.

I guess two drivers, running two different brands high end radios, 5 MM systems in 5 different vehicles on three different tracks is not enough to demonstrate there is a problem.

Again... this "problem" is subtle and many racers may not be bothered by it.

Serum 01.20.2007 05:17 AM

As with all companies; It's hard to convince them if they think they are producing 'the bomb'.. If 20,000 setups are sold, and 19,980 are raving about it, and the other 20 being very critical and notice flaws; the 20 critical people are wrong, and the other 19,980 are right..... (it's the easiest way out for cc, right?) frustrating for the 20 people.. but who cares, it's only .001 percent.. I had the same issues with that arrogant ass of schulze, and nova rc products.. I know how you feel glass... Too bad cc doesn't..

Bomb-Proof 01.20.2007 10:37 AM

Well, at least they arent schulze. I am sure I can make mine do the same, I have never found a controller I couldnt get to do it. The Hacker's were the worst about it, they did it after going to nuetral and getting back in throttle...they hit full brake first.

glassdoctor 01.20.2007 12:28 PM

Hey guys... just for kicks try something that demondtrates what I think is happening in "my" glitch:

You can try it on the ground or held in the air. Simply apply very slowly a very small amount of throttle until the wheels first move.... and let off. Do this over and over. What you see happen is that very often the car/tires will kick over backwards just a little before moving forward.

As some have mentioned, under severe cases this can kick your car backwards a couple feet.

But in typical MM running in 1/10 car 6 cells, etc... you don't notice this from a dead stop. It's always been smooth to me, but you can see that it kicks in reverse for a micro-second before correcting itself.

So, what I think happens is that once in a while it does this... fires backwards once.... while the car is moving. The effect is that you get a very brief 100% full lock brake (cause the tires kick over backwards for like .1 seconds) which is not good if you are racing a 2wd car through a sweeper for example. It immediately will point you sideways... like you just got bump-drafted at Daytona.

Now, the Mambamax is not "supoosed" to be able to do this... it's impossible according to CC. But it happens. The problem is you can't predict when it will happen or repeat it on command, so CC hasn't been able to duplicate this and see it for themselves. And even if they did get it to happen, they may not even notice if they are just running around a parking lot... you might have to be racing to easily see "it".

Maybe I've made this more clear to some of you now....

glassdoctor 02.06.2007 04:04 AM

TTT :018:

I swapped out the Neu for a Hacker in my 8ight and ran around the living room for a while... pulling wheelies :030:

On a similar note, I put the Neu in the 777 w/Mtroniks Truck esc... no cogging, not once. The Mtroniks doesn't have a nice slow stat-up... it's kind of jumps from a stop. But it never coggs, let alone kicks backwards like the MM. :mad:1

No cogging at all.... MAN I hope CC can make the Neu run like that.

One more thing I noticed with the MM and Neu... when you just crawl slowly.. it makes a high pitch humm for about 2-3 seconds and then it stops and is smooth as butter. Seemed to do it every time, from a dead stop... start driving real slow and listen. Once it stops this squealing (while still moving slow), it doesn't cog and felt smoother. Weird.

Larain60 04.13.2007 07:13 PM

About 1-2 months ago I installed a MM 5700 in my stampede. I had some cogging issues, and upgraded to 8 cell 4500's and was running Deans Ultras. The cogging would happen from time to time, but more importantly I started having radio issues loosing signal.

I just installed a Spektrum since I grabbed one on sale (2 RX plus free ship) and installed that. Heh I started having horrid cogging.

Anyway long story short, I noticed if I roll the motor wires between my fingers where the connectors are they "hook" up again and but after running a bit it would cog when at a standstill. So I disabled reverse in Castlelink ... and dont you know the cogging was eliminated in its entirely.

So the end result (besides a lot of $$ haha) was reverse disable, going to eventually hardwire motor and also better/newer battery.

Hope this helps someone.

glassdoctor 04.13.2007 09:25 PM

We have found that hardwiring helps a lot. Basicly the 4mm conns are crap. I have not tried the 5mm or 6mm beefy connectors but my guess is they would also be much better than the stockers. I just hardwired finally.... it's a no-cost mod. :)

Larain60 04.16.2007 10:53 PM

MM5700 glitching
 
Just to follow up I hardwired by mm5700 and the glitching was eliminated in the entirety.

Thanks.

glassdoctor 04.17.2007 06:07 AM

Nice!...

Procharged5.0 04.17.2007 10:17 AM

Good to know! I have 6mm connectors and 12g wire but have yet to assemble & test it. When I do I'll give you guys an update.

AAngel 04.17.2007 10:27 AM

The hard wiring does help. I temporarily went back to 6mm connectors, while I'm trying to figure things out with my setup, but when I settle on a motor/esc combo, I'm going to go back to hard wiring.

The 6mm connectors are nice, but they are still connectors. Some are tighter than others. Connectors are also prone to developing some sort of coating on them that over time adds resistance to the system. I'm going back to hard wiring because it simply takes one more variable out of the system and is just one less thing to worry about.

Procharged5.0 04.17.2007 10:43 AM

There is a chemical the ensure ultra low resistance. It's used in hi-end audio to maintain "state-of-the-mind" performance.

I think the chemical is called "TWEAK".

I'd have to search for it. It might be worth trying since its intent is to eliminate voltage drops due to corrosion and not-quite-perfectly-tight" connections.

AAngel 04.17.2007 10:51 AM

I do have this "grease" although it appears to be more of a gel, that is supposed to promote conductivity and prevent corrosion, but I'd rather just not have to worry about it. Hard soldering does't take long anyway. The only real draw back is that my spare setup will now have to consist of a motor and esc as one unit for quick swaps at the track. The spare is just going to have to wait.

Procharged5.0 04.17.2007 11:00 AM

TWEAK is a clean clear liquid. Looks like superglue actually.

I also have a copper anti-corrosion paste for electrical connections and use in on my car (full size). I'm not sure if it's characteristics would be ideal for hi-amp brushless systems or not. I'll have to look into that.
