The temps are fine. Keep truckin' and don't worry.

brushlessboy16, that was a good one!!!!! "black is nice"

I am putting that under my screen name!

hahah thanks for the compliment. Im black lol. I have the prototype castle/traxxas neu its really nice

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 :lol:

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 :mdr:

I ran my system yesterday in 50*(f) weather. all out-jumping burnouts, etc
Motor came in at 120* batt was 117* and the esc was about 110. In the 15 packs that i have run through the v3, the fan has yet to come on :)

alright gentlemen looks like patrick has cleared up the safe operating neu/caslte motor temp question :party:

"Never allow the motor to exceed 170F during runs"

also check out his newest post pending to be a sticky, all the important info you need to know about your MMM COMBO!

thank you Patrick! :yipi:

Mine geared for 38mph in my e-revo(20/62 with 6.3inch tires) low timing, low start power , 70%punch and have been seeing 175*f on the motor when running somewhat hard(about 50*f out) . I was told by castle on the phone that it was ok!

Can you gear up? A smaller spur would do the trick, unless the motor is too big in diameter to allow that. I know it sounds strange, but there's the possibility your motor is undergeared.

On the Traxxas forum, Patrick said this,
"The CC/Neu is also good to 60K rpm and 200F. We have run both on the bench and in the field. Above about 240F (internal temp) the glues start to weaken, so 200F is considered maximum, and 170F safe temperature for runs.
" ^^^ just to make clear to anyone that still has the question, it is ok to get up to 200* but not good for it to really stay around there.

Thanks guys. I just got my combo coming, your great info is a guiding light for me to set up my Tekno Losi 8-T

I had it beared for 42 and it hit 175 in about 8 mins and my enerland 6000s were at 128

update*

ok so i ran my e-revo at the track last night, at revelation raceway in Ontario CA, with the MMM combo and it was great! it was much more powerful than my old novak hv 6.5 (geared 15/68)... i thought it would be to much power as a must admit the novak was decent on the track with good all around performance.

side note - Adam Drake was there, Team Losi's Pro Driver, he was running i beleive a losi 8-e buggy. i stopped to watch him and "WOW" driving skill is incredible, killing people on the track and the buggy was looking graceful doing it... but it just made me think even more how electric is making a serious comeback for off-road large scale racing that pro drivers are practicing with electric... and I'm confident the MMM Combo will be the top choice in performance, as the 2009 racing season approaches.

the MMM combo was awesome i had it geared 20/62 and was running my proline bowties lpr wheels... the most noticeable difference on the track was clearing the triple was a breeze, if i could get the wheels to connect all the time :wink:, and in the back stretch it was it was a "MONSTER"

the temp outside was 55F and the motor couldn't break 135F the ESC fan never came on and the batteries were about 85-90F :yes: the operating temps were consistent, so i was able have a long practice session without any fear of temps going to high.

granted on the track you are not able to be heavy in the throttle and therefore allowing temps to be reduced, but with 170F being a safe threshold even for bashing the combo does excellent. i didn't gear it back up on the track to 22/62 as it was plenty powerful and if i wanted more power i could up the starting power and timing from low, but no need! also these temps were achieved with no fan on the motor no holes in the body for cooling, so i feel comfortable saying geared conservatively and esc settings on low, at the track you should be fine with temps. also with the 8000 packs i was able to get about 25-30 minutes of constant run time with plenty of power for track, i am happy with the spc packs for the price and quality they do great, if your thinking about getting them and know that you are not looking for a 50mph monster but solid track power and all around decent bashing they do well. i did get through about 3 sets of packs, with 15 minutes of motor/esc rest between.

i also noticed that the motor seemed to run smoother geared 20/62 vs 22/62, could be just that my batteries are not the highest C rating and the motor turns easier with 20. i think i will keep this gearing for awhile as it seems to be a good balance of power and temps... although i need to retest the temps with this gearing on road again to see if i get up to 170 as i did geared 22/62.

the esc holder pictured in my other posts did pretty good on the track but i did get a little bit of movement so unfortunately i will be using some Velcro or double sided tape under the esc for added slide protection.. but for the time being till the factory one is available it is a great solution.

one other note, the motor being so long on hard landings will bump against the back of the shock holder.. dont know if it is a big deal (dont think so) but it does make my sticker on the back of the motor start to peel off, and the sticker on my MMM was starting to get weak and peel as well...

any chance you guys think castle would send a few stickers as replacement to keep the products looking new and fresh :wink:

i know the review is long, again!, but i hope these reviews will bring value and confidence to everyone running these combo's

also its redundant but, thank you castle for a bad A@@ combo, it was worth the wait!

I'm pretty sure we already went over this in your other thread. It's your driving conditions. On sand dunes as you can't use the same gearing as you normally would otherwise.

when geared for 42mph(22/62) it was on the road and in my yard. Not the dunes. Geared 20/62(38mph) was on the dunes.

Well put a hole in the windsheild today to see if it would help. Geared 20/65 it never broke 125 in the yard after 15+mins. My pinion slipped and killed the spur so I put a 58t on it and after 10mins I checked it and it was 131. I am surprised that the 1 1/2in hole helped out so much. It was 45* out today. Apparently the e-revo body doesnt let much air in there!
