I really need a primer on volts vs kv
basically if you volt up and lower the kv to he point that it has around the same speed, the higher voltage set up has less amp draw and less heat, I don't know if you allready have 3s batteries? if you have you can try bying an cheap 3660 2200kv motor and run that in the car, I think the max10 esc can handle it, arrma sells the 3s line with basically a max10 and they have a 3660 motor and can run on 3s

So before I make another expensive mistake, is the 3200kv version of the 3660 the most appropriate output for an Outlaw?
That is the lowest kv version they have for the 3660, but you have a 3300kv in it now, so I think the 3660 it wil not get so hot as the 3652 can motor I am supriced if it is, or search for a low kv 3660 motor about 2200kv and run it on 3s then the car has more power and more torque but stil the same topspeed and less heat.

So basically, go big or go home….
yes, I f you have the money for it, then buy the sct combo it has more power and it wil help with the motor heat, I have the sct esc in my rustler and losi rock rey.
Maybe you can sell the max 10 combo or use it for another car.

How easy was it getting the diff out of those? Mine feels like it literally has no fluid in where is spins so freely.
It is easy, you have to pull the transmission out of the chassis and get the diff out, the diff oil what is in there is very thin the manual says 1000 weight, mine felt like there was nothing in there, I have put 50.000 in it, it is much better now.

Did some more building on my brand new hpi jumpshot mt, I rebuilding the whole car and do so some upgrades, today put in a better servo, it was a hair to long so I made some spacers, rebuild the diff and put 50.000 oil in it instead of 1000 I don't know why there was such light weight oil in the diff it was allready leaking out of it.
Ditched the 48p spur gear and fitted a arrma 54 tooth 32P spur gear with associated high torqeu slipper pads, perfect fit, and changed the ball ends for tamiya ones, the hpi ones are hard plastic and pop out easy the tamiya ones fit more snug and are hard to get off.

losi 22s sct, wanted a 2wd sct truck sold my serpent some time ago and I missed it, saw this for a very good price £227 for a brushless sct truck it looks like a decent basher and there are a lot aftermarket parts for it.

So will a 3660 3200kv be torqueyer and cog less as well as run cooler?
I wil run cooler and have more torque but only if you buy a hobbywing or a good brand motor if you buy something like a gool rc motor then you can save your money and leave the 3652 hobbywing in there , wil it cog less I don't know

Do you know if this is available with a 3.17mm output shaft? I don’t know if there’s a pinion compatible with my spur that will accept a 5mm shaft.
If you look at page 6 of this tread you can see a 3660 motor fits, and 0.6 mod pinion with a 5mm bore are also out there.
maybe this can help.

Your in the same position i was in, no choice on gearing down, so just make your own transmission 😉
Theres no 5mm pinions for this transmission.
You wont fit in longer the can without modifications. 3652 is not 3665 the max can size is really 3655.
Put a fan on the motor not much else you can do, least its hobbywing and wont kill itself.I know a 3665 is not the size of a hobbywing 3652 motor, I asked of a longer motors fit because that can help with the temps, it seems like a 3660 motor fit, if you read the early pages of this tread there are people that have put a 3660 motor in it so it fits.
I was only trying to help, but saying there is nothing you can do is not right, even 0.6 mod pinions are out there with a 5mm bore.

what mod gear is it ?
I see it is 0.6 hot racing makes then, but I do not own the car so you have to measure how much room you have for a longer can motor.

Definitely looks like I could fit a longer can in
Yes I think a 3660 fits easy, bigger I don't know you have to measure it, if a 3665 can fit this one I have put in my rustler 4x4 good motor and I do not break the bank https://hobbyking.com/nl_nl/turnigy-xk-3665-3190kv-brushless-inrunner.html?wrh_pdp=1

Damn, I had asked around for advice before purchase and only fitted it last night! 😂
Thats a pita, when I have a car that weighs more then 2 kilo I always put a larger can motor in because I know It wil get to hot especially when it is 4 wheel drive, the only car that you can get away with it is a crawler because of the low gearing.

The internet says weight of 2.2kg, Gear Ratio: 11.2:1, mine does about 30mpg on 2s - I’ve not released since fitting an HW Max 10 3300kv combo yesterday
Nothing is bind in the drivetrain maybe bad bearing ?, If not , I think if its a normal size can 3652 hobbywing motor it is a little bit on the smal side for the car with that weight, I see you can put a longer motor in there I think that your better off with a 3660 size can motor or larger if it fits.
I had the same on my ruster 4x4 the car weight 2.3 kilo and it had a castle 3652 can motor in it, that was fine for cooler weather but with warm weather it was getting on the warm side for my liking so I swapped it for a 3665 can motor.

What’s the answer though? Motor fans? The Outlaw body is pretty open anyway so I wouldn’t expect airflow problems.
Volt up, gear down? 3s and smaller tyres?
I don't know nothing about the outlaw, a fan can help, but for what kind of speed is the car geared and how much weighs the car?

I hope that it works for you, I did not liked it brushed, I still have a wr-02 with a 3800kv motor in it with high speed gears I like that car more because it is only rear wheel drive you do not get the front roll overs that you get with the gf-01, and I widened the wr-02 so it do not roll over a lott, but it is stil a wheely king.

Oh, is that a thing?
If the motor was getting to hot a few times you can damage the magnet, the magnet is getting weaker and starting to pull more amps from the batteries.

Ran well, much cooler can temps - no real run time increase though.
Do battery run times decrease as the weather heats up?
No with warmer weather you get longer run times then with cold weather.
Maybe the motor is overheated to long and damaged the magnet so you get poor runtimes now.

Cleaned out the 1 million oil out of my new center diff for the rustler 4x4 and put 100.000 in it, and mounted it in the car.

Traxxas center diff for the rustler 4x4 and a 13 tooth 5mm bore pinion.

it is top heavy, I have weighted the body some time ago, and if i remember it was about 380 grams, mine I ran only on very loose sand it was undriveble on grass with the castle 5700kv motor in it and still on sand I had to be gentle with the trigger.
Did not want to put a brushed motor in it because for me it was then to slow and boring.

rebuild the shocks from my brand new hpi jumpshot mt, they had to much pressure in them 3 of them I can only compress half way and one of them only a little bit, had to sand the pistons a little form acces mold, and on the front shocks I put other springs on them , the stock ones on the front are to stiff and the rubbed the tread of the shock body, so they are nice and smooth now.
RTR still means ready to rebuild😁

My new HPI Jumpshot mt flux v2, not going to run it jet, ordered a wheely bar and the bumper from the short course model to protect the body have to wait for those to arrive, I going to replace the servo with a metal gear one that I have as a spare and put some thicker oil in the diff and put my own reciever and transmitter in it, maybe I swap out the motor and esc and keep this one for some other car, I have a castle 1410 3800kv motor and a hobbywing max 10 esc in a box, and check the whole car before I run it, I never run a rtr out of the box.

4s kill the car and breaking parts , I don know how strong the car is but even on 3s you can get driveline problems, I don't no how strong the driveline is on the outlaw , maybe you can find anything on the web if people running the outlaw on 3s and if the driveline can handle it before you buy a motor or and batteries.
maybe you can try an lower kv motor like a 2600kv 3660 cheap surpass hobby and run it on 2s and then gear up if the motor temps are fine
