Customised R1pro maybe ?

or the good old custom Mamba Max + BEC

Yeah, a R1Pro with two 35v, 1200uf caps in parallel and a decent external bec will make a very good 2-6s controller.

Tekin seems like the best contender. I think the newer MGM escs might be a good choice, too.

This 35v caps in parallel, yo have to put it in the input batterie lead, right??
And how is the current rating of this R1pro??

Maybe this think could be better than my MMM on my e-revo on 6s, hat do you think guys???

100 amps continuous, 200 amps surge.

I'm not very sure of the 6s handling. The whole case is plastic and only the solder posts work as a heat sink. Many people here have reported very positive comments on the esc's performance at 18v( 5s), but not 6s.

I still think it's a robust thingy. Maybe a cooling fan will solve the problem at 22.2v.

Mike was working on an aluminum case for the r1 pro, but I forgot what he said about...mike if your reading this give us your thoughts on the r1 pro bro!

MGM manual are still complex and difficult to read...

i actually thought they were laid out quite well... Just have to read it once before you do anything and it sinks in the second time when you go through it all with the controller (i found anyway - as i was quite confused at first - i just had to read through the whole thing once to get the jist of it all, then it just made sense the second time when i was setting it all up)

I run an older plane version of the 16024 in my LST and it's worked very well for me for quite a while now... Have an 8012 somewhere too and plan to get a 16025 z series for my savage soon =)

It's wierd that they even bothered making the z and e-series... they're all the same except one can't use the black box... the difference is only a few euros (15 at the most), so i'm confused as to why they bothered with the e-series...

The mgm manual is a breaze, I had my mgm calibrated and fully programed via the transmitter in less than 5 minutes if even that long. Mike also agree's with me...both him and I have the usb module and connection cables for the pc but never use em cause its just as fast or faster to use the transmitter! Anyway I want that big z series esc for a 50'' bonzi conversion I want plus I want one for my baja project.

I plan on using one of these in my converted revo3.3, with a medusa 60mm 1600kv, 6s lipo, 2-speed and geared for 40mph (18/40).

Would this one do:TMM 12025? It's rated for 120amp max continuous current and 150 peak current, and the medusa is rated for 93amp peak current.

Yes I think that would work, I would have to assume so...I would shoot for the 160.24 mike says that one is tuff as nails.

but why go for the 160.24 if the 120.25 will do the job aswell? these controllers don't come cheap, and if there isn't a reason to go for the 160 instead of the 120, why would I???

Myself, I would prefer to go overkill than to have to buy the bigger one later. The extra $50 - $75 is a lot less than buying both controllers if you smoke the smaller one. Keep in mind that the motors could possibly pull more amps than the rated max if your set up is not ideal for the motor

thanks for the answers. so you recon 150max amps of the controller vs 93 amps of the motor isn't enough margin?

may be the price difference woulfd be less if I could run the 160 without a fan?

Not sure if it says on the website, but do these controllers have a built in lvc? Specially the 28025, it says it has:

When batt. low (almost empty) - motor power reduction
When batt. low (almost empty) - instant motor cut-off

But wasn't sure if this was programmable? So do you need to get an lvc with this controller?

thanks guys

All Programmations
 

It is possible to adjust the lvc in the E & Z series ( new generations ).
Go to web page, softaware + instruction manuals.
The pdf shows all parameters adjustables: :rules:
http://mgm-compro.com/manuals/en-man...d240808-02.pdf
pages 8 + 9 shows all.
I own old & new versions. Regarding the new one, the parameters
are perfect to adjust to your driving style & personnal use.
The programming can be done by transmitter+ programming card or
computer if you buy the connections needed.

Definitely the best ESC now available.:intello:

IMO you don't want to run a 2 speed tranny in a BL Revo

I'll wait for RX8 from Tekin :)

Waiting
 

I choose MGM because they are strong and available for a while
with no issues at all since my 1st run.
If you compare to some theorically welknown esc, they give so much
troubles and are already thinking of producing the V3 with the 2 old
versions having HEAVY issues: burning, no operation, BEC out of order
and much more. Customers are making the tests, but still without
reliable solution. Not appreciated by myself.
I never get a BEC problem, and i can tell you that both my MGM esc
have been tested VERY HARD.
Anyway, it is your choice if you have time to wait. Meanwhile, i run
alot with mine in total trust.:na::lol:

Why wouldn't I want to run a 2 speed in a bl revo?
I know everyone runs single speed or lock the tranny in second, and I know brushless motors have enough torque to run on a single speed. But I'd like to try out the extra efficiency from a 2 speed.

i think it would be more reliable, and it would change to 2nd vitrually instantly i thouk you will find.

multi speed trannys were made to make up for weak power plants, we have had a few members here that have tried it just to see how it will turn out and in the long run they all removed them. Unless your goal is to pull wheelies and nothing else go with the 2 speed. With my first Revo conversion I actually went in the opposite direction I did the remove 1st gear, lock in 2nd mod, it still pulled wheelies, put in the wide ratio gear set, still pulling wheelies somewhat and geared up the pinion and spur to 38/18 and was happy with that...my latest is a slipperential Revo which I am the most pleased with

I get your point, and no I don't want wheelies all the time.
So I basically should be looking for a motor with lower torque than used in common setups using single speed tranny's?

Test Ok
 

Tomorrow i race with the MGM E serie TMM 28025-3 Car on a
truggy Eight T with NEU 1515 1.5 DF.
I went today for practice and it runs perfect. Even when grip
is low, wheelie on throtle-up is no problem.
I set the cut-off at 3.2v. After 2 hours rest, my pack gives
3.38v and i put back 5100 Mah on a 6000 pack ( Poly Rc ).
I run 17 min hard, up to the max slow down of the ESC.
The car was fine on this track with a standard setup.
By the way, it's the 1st time the T runs.:party:
BUT, tomorrow is another day:
3 x 5 min qual + 3 x 15 min race.
My STRR truggy will race with an old MGM EXPERT+ 28025-3 and a
NEU 1515 2D. Smoother on gaz but not so thursty on packs.
I can run longer with a lower Kv.

Brushless: 2 truggies + 3 buggies
against 45 smoky....
Wait & seee :whip:

Running Perfect
 

The 2 truggies made the all races without any troubles.

STRR + old MGM made qualifications 5:3:1
The 15 min finals were with starting position B4
Ended 4 + 1 ( 3rd canceled due to the dark )

eIGHT T with MGM E serie made qualifications 5:2:4
Starting final A9 and made 5+4.

No doubt that the MGM are strong. The track was very slippy
on 1 side and a lot of grip on both side. It's always U turns
with brake max + nearly full throttle with wheeling sometimes.
The packs were just to hold the 15 min but this track needs energy.

By the way, all 3 other brushless ( not Neu & not MGM ) didn't end
a qual or final without thermalling.......:oh:

Total with MGM: 8 races + many practice = +/- 12 hours run.
No fan breakage and no troubles:
DO YOU KNOW WHAT? I'AM HAPPY.:mdr:

I'm hoping that my mgm will be as durable as yours after I send it in for repairs.

Model
 

What model do you have and what are the problems?
The version Nr of the controller is on the sticker and can be seen
on the computer screen as well.

I have the 16024 with 3.13 firmware. It just decided to smoke on me running 6s1P A123 cells.

TRUGGYMAN,

Nice to hear your MGM's are doing well.

My 16024 (now ver. 3.23) has 20 - 30 hrs and runs great, I may have to pick up one of the new ones soon.

Nice job TruggyMan. :party:

That's very strange. Maybe a shorted FET somehow? 6s A123 is nowhere near the max voltage so there's no way it could've been over-powered.

3.13 Ver is quite old. I would ask for the latest update allowing the later
downloading of new version.
Do not forget to buy the USB com++ & the cable CC_O3.

By the way, all my connections are done with connectors MP JET 6mm.
They are hard to pull but never got loose or warm.

Just wanted to add my ongoing experience with the MGM controllers.

I don't know if it is OK to post links to other forums but my entire ordeal is posted in detail with pics on the Traxxas E-Revo forum.

Back in July I bought an MGM 16018 from mike along with a 1515 2D for my new E-Revo. The ESC went up in smoke after a total of maybe 15 minutes run time (3 5 minute sessions). I had not even done any full throttle runs, I was still breaking in the motor.

The original esc burnt on July 21'st. I finally received my replacement controller (a 28025 instead but I did of course pay the cost difference) on Sept 20th. 6 of the 8 screws that hold the heat sink's in place were loose. I sent pics to MGM and was told to carefully tighten them. The first one I tried to turn broke. Yesterday I sent it back the MGM. They did say they would ship me a replacement immediately instead of waiting to receive this one back.

I am very disappointed with the MGM customer service. I know there is a big time difference and it takes a day to respond but I had to wait days for responses sometimes and had to call them on my dime 3 times to get responses.

I wont be buying any more of their products. In fact I will probably sell the replacement controller when I receive it as my car is up and running (for the moment) on another controller.

As a side note, Mike has been very supportive during this whole process and I have no gripes with RC-Monster at all. I am happy with his customer service and will buy from him again.

Screws
 

Being a driver is 1 thing. I'm more a modelist. :rules:
All what i have in my hands is check and made better if needed.
Concerning the screws, when i got the ESC from MGM, i took
away the 2 fans and put some thread lock on the 2X4 screws holding
the heat sink's. Afterward, i mount 2 grill in front of the fans, taking
care that the grill is away from the fans. An "O" ring makes the job.
The screws for fans & grills are locked by yellow paint.( see picture ).
Glue the connecting tap of the fan cables and check that the cables
are not trapped with the heat sink's.
The esc mounting on rubber damper helps a lot.
All my loose cables are protected by plastic coils ( Don't know the name
of this beautifull accessories )

Regarding the smoking of the esc, do not forget to set all parameters
before starting driving. A bad Battery choice would probably destroy
it.

Having a mail answer is already a very good point. You want it quick,
everybody does, but having a positive answer is THE POINT needed.
Many do not answer at all. You would be totally upset if so :diablo:


Just my experience.

Now In The RC-Monster Store
 

I see Mike has some of these in the store now.

Too bad only the 6S models. Would be very interested in a 10S or 15S model if he would stock them. His prices are much better than ordering directly through MGM.

Send Mike a PM and see if he can put the one you want on his next order. He should do it for you.

Mike did offer to order what anyone wanted earlier in this thread.


I too would like at least a 10s one, just don't have the funds right now, doing a mini (1/18th) for a winter project. I will likely get one in the spring, maybe get my LST2 project off the ground.

thanks for the notice bdebde, just put my order in for a 28025 :yipi:
