CC/Neu 2200kv Combo Temps/Review!

[rrgirgis]

Hello all,

this is my first post, its a bit lengthy!

first i want to thank monster mike for adding me
also all the people on this forum that have shared there knowledge and ideas.

I have recieved my 2200kv combo!!! thank you superfastrc for the superfast shipping, great company and awesome service!

i was running it last night and all i can say, which is an understatment, is "WOW" this thing really is a monster, tons of torque throughout the power band, insane top speed and grin from ear to ear the whole time! bring on the nitros, they're for breakfast!

thank you castle! you guys have brought a world class product (as all of your products are ) with the Mamba Monster, that i really believe will change 1/8th scale rc racing (nitro whats that??)! nice work on the deals with traxxas and hpi both awesome trucks!

i wanted to post some of my temps with the combo in my E-revo after some hard asphalt and grass running... but let me first give the specs of what im running exactly; so the data will all be there to see if im within good limits or need re-gearing or adjusting anything.

car: e-revo - stock diffs/transmission gearing
setup: MMM COMBO 2200kv - cant stop grinning
Gearing: 22/62
tires: stock talons on 17mm hubs
Battery - SPC 12C 2s2p 8000mah packs
Deans Ultra plugs all the way around and 10gauge wire for consistentcy
calibrated remote to MMM, DX3R epa is 100
MMM Settings -
- timing low
- everything else factory default

i ran 2 sets of the same packs through last night and the good news was temps were consistent. outside temperature was about 55F

Motor was at its peak end of hard run - 165F when i checked periodically the temp was about 145-155F

Esc - never broke 120F it was about 110-115F most of the time, funny thing was the fan turned on at the 110F mark then when i went to check it, it turned off in about 20 seconds - is that normal? i know is supposed to come on at about 150F but im not complaining

Battteries - the hottest they got were 125F, but most of the time around 105-110F... i beleive spc says no hotter than 140F

My question is what do you guys think are these safe temps or should i make adjustments? i was thinking also the temp outside was 55F which is cool, so on a 80-90F day would i be close to unsafe temps?

also i know you guys might be saying we want pics! i know i know i will post some and i have a special treat for all of you e-revo fanatics that are getting the combo or have it and are saying how am i going to hold down the MMM ESC without the factory holder???

i have a holder that im sure all of you will like - it costs near nothing and it works awesome! i will post pics (nope! it doesnt have velcro, tape or zip ties!)

p.s. i have posted this on the traxxas forum and wanted to get your guys input here (thanks vxl and lee for your replys)

I would gear down, the higher c lipos would also help. 165 for the motor is a definite no-no

Gearing down seems like it will be better all the way around

i agree im definitely going to be going to the 20t pinion.. i know you have been running the neu/castle motor for a while longer as a beta tester... what gearing/battery setup were you running and what temps were you getting? was it in an e-revo?

i like the castle green motor :)

[rrgirgis]

i wanted to post LEE's response from castle to my thread in another forum...

"Those temps sound about right. These motors are very comparable to the NEU motors. You certainly should not feel that the green ones are any less good than the black NEU motors. We truly licensed the design from Steve.

The fan on the controller is controlled by a temp sensor. The heat sink and controller are very efficient conductors of heat. The fan does not need to be on long, especially if the ambient air is at 55! That's normal."

its odd im getting responses that motor temps are too hot and some normal, hmmmm... im thinking that the neu/caslte motors run hotter than the orginal neu's but its not a factor as the motors are rated to run hot according to PDC.

the fan coming on before 150 and for a short time is normal

Hey, Pat's response and mine are on the same page, we agree. I would hope that you would take Pat's post as the definitive answer...

The Neu Castle motor and the Neu motor compare very favorably. I can't tell you one is better than the other, we sell them both! The green ones do offer some design features in the case that are put there for your benefit.

Not sure I like the sound of "rated to run hot." I don't want anyone to miss out on playtime because they cooked their motor. The old rule of thumb (flesh) is to put your wet finger on the motor when it is hot. If it sizzles, you are too hot. If your finger burns, I didn't tell you to burn yourself, put the lawsuit away.

I'm also concerned that there are both Celsius and Fahrenheit units being tossed around here. The temp readings that you take are going to vary based on exactly what part of the controller or motor your IR sensor is picking up. The hot parts of the controller are packaged pretty tightly/hidden under the heatsink. The controller's temp sensor is pretty accurate, it knows what to do. I don't think you'll see them varying much, so don't think your setting may be off compared to someone else's. The settings and the parts are all the SAME.

My hope is that you guys will get these units and install them. Go run them and see how stupidly fast they are and then gear back a bit to a point that is rational. That will also probably be a setting that is a bit less demanding on the components.

Playing with the timing really won't provide much / any noticeable increase in power. Especially with the motors like the NEU & NEU CASTLE. What advancing the timing WILL do is increase the heat generated as the motor will become less efficient. So leave that timing alone.

thanks lee, i should correct what i wrote "rated to run hot", i ment that maybe due to some of the minor differences between the two motors you might get a little higher average running temperature and that is normal for the neu/castle motor...
as more people get the combo and run them there will be more feedback on temps...but i agree dont go running the motor to the max and expect it not to get damaged or have a burnt finger

Given the fan temp sensor location you mentioned then i would see how my reading at 110 would not be correct, it is to small of a place to get the accurate reading with a temp gun. however i did get the same consistent temp reading when the fan came on, so most important as your saying the MMM is working right

the motor timing i beleive comes default at a higher setting then low, from my first run with it on normal to my second run on low it didnt make that much of a power difference. i agree, on all the castle controllers i have used when i adjusted the timing i never saw much of a difference in power, unless you go from low to max, but with it being at low you get a little more run time and a little cooler temps.

P.S. the MMM COMBO IS STUPID FAST... BUT YOU GOTTA LOVE IT

[MTBikerTim]

I'm pretty sure castle has reduced the temp the fan comes on at with out telling anyone. My v2 fan never used to come on but my v3 one comes on almost immediately depending on the ambient temperature.

[Arct1k]

PDC quote

"If you were able to hold your finger against the motor at all, it should be just fine. Damage temperature for that motor is around 150C (which would sizzle and burn you right away) and safe operating temp is as high as 120C (which would sizzle a little.)"

[rrgirgis]

without further delay here are the pics as promised of the setup and the MMM strap!






Can anyone guess what part is being used????? that one! and it works awesome! flips, tumbles, asphalt slides, next test is at the track but holds solid!

[Jeremy1976]

That is the steering stop thingy.

[rrgirgis]

Ding Ding Ding , yep it sure is...

i swapped out the stock steering stop for the upgraded one that comes with the e-revo for extended travel, so i had the stock one laying around...

after some minor dremmeling i got it to form around the ESC, i used some fuel tube to shorten the screws and some fuel tube at the bottom of the screw for added support and it works awesome

the screws i used were the 3x32 cs 3694, the ones that hold down the support for the shocks

That is pretty frickin sweet ! Good job , I like to canabalize parts too work in different apps too !

Here is an idea for ya , you could put a square of plastic mesh between the hold down and ESC too keep debris out of the fan .

Gonna borrow your idea for the hold down also

So are you using the pinion that came with the MMM combo ?

[rrgirgis]

I am using the Robinson racing 5mm 32p 20 & 22 tooth pinions and now that it came with the 18 im set with pinons... i am going to be geared 20/62 with a 4s setup im hoping that should be a sweet spot for this combo

i was thinking about putting a piece of mesh between it but voted for using Velcro on the battery tray and the inner body to keep the body locked to the truck to prevent any debris from coming up through the gap..

I still like the traxxas version of the motor :) black is nice
