Yeah, lets see the butt end!

Man I need help!

yah i can get you that deal. just u got to pay for shipping. i well get some pics for you tomorrow.

I might! hehehhe

Something that makes me wonder here, in comparing the turn count to the AXI, these are ratings are just about the same for half the turns. I wonder if this KMS motor is a Wye wind?

THAT would make it even better IMO. It would be especially nice if the fan will fit. Does it have the 3 screw holes in the endbell?

1090kv! :yes: Every little bit counts. LOL

I would like to get one, install it and compare.

Excellant Dr Kros. I appreciate that. Not a problem on the shipping.

I can get some side by side comparison with the AXI this way. :yes:

yah i think it does have the 3 screw holes in the endbell

I took the E maxx out for a run again today on 4S. 4S is perfect for this. Motor temps are in range, ESC is cool, Lipos are cool.

A couple of guys at work are getting into the hobby. I plan to run them with this setup.

One guy just bought a new T maxx 2.5 and the other is picking up one of the new E maxx's tomorrow.

I'm not gonna show them how this one runs until they get their's out. LOL

It's gonna wax their butt. :rofl:

Just a thought, how about a pair of them, since they are using the same spur you may be able to wire them to the same esc. Griffinru did it and I have a pair of aveox motors that i wanted to wire to the same esc, but could not figure out how to time them the same. Someone recently posted to hook up a battery to two of the leads on each motor and they would be timed the same.

That's very possible. I might try that. It would work with much higher gearing then for more top speed. Use the 25 tooth pinions with a 36 tooth Revo spur. :yes: Hmmmmmmm..............

Dr Kros, I want the 4 turn.

In comparing the internal resistence values:

AXI 2826/8 is 30 mohm's

The KMS 2826/4 turn is listed as 64 mohm's.

If I were to speculate, my guess is the KMS is a Wye wind. This might make it even better than the AXI. I wonder what kind of magnets it uses?

Another thought here is, I bet the AXI endbells would fit the KMS stator assembly perfectly.

You sure about that resistance? This page lists it as 32!

http://www.hobbypeople.net/gallery/108510.asp

The KMS resistence value at that website must be wrong, another site I found lists it as being 32 mohm's.

The AXI 2826/8 shows 2.8 amps no load at 10v

The KMS shows 3.2 amps no load at 10v.

Something isn't right about these figures.

Greater amp draw usually means higher kv and lower resistence.

Aaaah, see that prop adapter in the picture?

It does have the 3 holes in the endbell. There's a pretty good chance the fan will fit it.

I guess testing will be in order.

Is metalman using a kms motor in his direct to diff drive mt2?

Yes I think he is. :yes:

These motors might be a better choice for that boat project too.

he is also using one of these motors in is 4x4 rock crawler

I replaced the Quark 125 amp Monster Pro in this setup with the Mamba Max ESC.

I haven't had a chance to really put it to the test yet. We have another ice storm in progress. Ugh! LOL

I have to hand it to Castle. Just with Low Speed Carpet Running, Startups ARE MUCH BETTER! The first low speed throttle step on the controller will start great with NO cogging and move really slow without stuttering. Or WOT will go wheels up on the blast off.

It appears to me they got it right.

I love the PC link. Wouldn't High Timing and High Start Power be best for this setup?

Thats the general rule- higher the number of poles, higher the timing/start power, at least if you go by what all the instruction say. I thought you were the expert dude? :mdr:

This is good to hear, I would think that high start power should help, I have the MM set to that way for my Plett maxximum in the crt.5

Not sure about the timing though, do outrunner require more timing advance?

I would have thought that since they run slow they would need less timing.

The KMS equal. says 20-30 degrees of timing. MM only goes up to 20, so that's where I put it.

I pmed Metalman about a possible "hook-up" on the KMS motors.

I guess the lower kv versus inrunner motors doesn't make a difference. I know the phase switching via esc is alot higher per revolution. From what I understand, the timing is just the precise point of phase switch in the rotation.

Just finished the first Mamba Max test run with this setup. :yes:

I have ran the Mamba Max in the beginning when it first came out, and I really didn't much care for it. It didn't work with outrunners at all, and I had glitching, along with radio range issues that I couldn't figure out. The range issues disappeared when I switched to a different ESC. So go figure, I dunno.

But for me in the beginning, there was this "black cloud" that followed the Mamba Max around, so I steered clear of it. I opted for the higher priced Quark Line. I have been very pleased with the Quark ESC's. I now own 3 of them. One 80amp, and 2 of the Monster Pro's.

IMO, this Mamba Max isn't the same speed controller at all. It just gave me a performance, I must say, is slightly better than the Quark did with this setup.

It's must be more on target with motor timing, because I'm seeing cooler motor temps. I do have the punch control set to 100%, which could be the root of the cooler temps. But this is just another great part of Castle's programability.

The ESC ran cool. I was very surprised at this, because when I first tried it with outrunners, it didn't want to run them. It would thermal within minutes.

It gave me about 4 more minutes of runtime. Could be I drove it a little different. Could be that the punch control helps tame starting amperage spikes. BUT, there was a ton of dirt and grass hung up in the drive shafts and wheels that I blew out with compressed air after the run. So Tit for Tat, I think it's more efficient.

This "New" Mamba Max knows exactly how to start this outrunner. It even sounds different in doing so. Ultra Low speed on the trigger or grabbing WOT, it doesn't matter. Brakes are smooth set at 50%.

Way to go Castle!!! With the new MMM having this firmware and seeing how this setup performs, I am sold!

Now I'll shut and take my place in the waiting line for the New MMM! :great:

So you like the new firmware then I take it?.... :mdr:

Great to hear, I may put a mm in the redcat and some taller tires for more off road use. I will run it on 4s, as 5s will be too fast with taller tires.

So a high setting on the punch control helps startup? You had it set to full on at 100%, kind of like a cutrrent limiting feature then.

Hoping that the mm will be able to hadle the higher loads placed on the axi by the taller tires. You are running the higher kv model in an emaxx, albiet with more reduction gearing than I have with the redcat, that is considerably lighter.

On a side note, I received all of the parts I will need to get the next revo ready, just need Mike to release the center diff with the integrated slipper. I am thinking that one of the century motors would be interesting!

THat is good to hear seeing I just got my outrunner which I will be running with my mm.




Thanks for the great info

No, the high setting on the punch control doesn't help startup. Startups are great. I just put the punch control like that to try it out. It's not a current limiting feature really. When I stab WOT, it's like it eases into full throttle. Maybe 1/3 of second delay. This allows the motor to start and get going, before the full amp load is allowed. It's intended for traction control.

Punch control does help tame the wheelies and makes this more controllable. Which would be great for track racing.

Have you found us a better deal on the Century Motors? My "NEW" E maxx transmissions should be here today. Where's that mail lady? LOL

The MM is looking pretty good here. :yes:

The new firmware is what this controller needed all the way along.

Castle needs to come out with some new advertising. It's VERY different and better now. :yes:

Just a little additional information to pass along here.

I got a chance several days ago to run this with a couple of buddies of mine.

One of my friends had a stock E maxx 3905.
The other had a T maxx 2.5.

This of course pretty much smoked the stock E maxx, but to my surprise it also outran the T maxx.

It took the T maxx pretty badly on acceleration, but would also outrun it on top end. At least for the first half of the pack.

During the last half of the pack, top end was a VERY close match. I could still out accelerate him though. :yipi:

Nice
 

It is always nice when our elecronic monsters can hand the head of a nitro want-a-be me in a face to face match up. That project of yours has been quite an imspiration on here Sikes. We all wish that rewinding a motor like that was easier for all of us to do. You sure put a lot of work into that motor and getting that truck setup the way you have it now:lol:.

Good work in kicking T-Maxx butt.:yipi:

Thank you Jerry!

This is a stock "out of the box" AXI 2826/8. I didn't rewind this one or pull any special tricks to make it work.

Only thing, Mod 1 Gears! 22 tooth RCM pinion on the motor and a Revo 40 tooth Mod 1 Spur gear.

nice one!! whats the total weight without the batteries?
