Get a temp gun - unless you are very experienced you really need a temp gun to tell anything

PS Airflow is key - Any windscreen holes in your body

Your going to end up spending hundreds of dollars diagnosing a phantom problem when you can spend 20 on a temp gun

there have been times where i have felt my motor and could have sworn it was cooked, but then the temp gun says 160, which aint bad.

Just get the temp gun....

Well to put in some input. I have sealed the motor like Freeze did, running 20/44T with the same exact 2s lipos (Turnigy 5200mah 30c). I also have the heavy-ish TCS 5mm chassis, but i am running on Masher MT tires whith RPM stablemaxx wheels (Smaller than stock tires). Anyways, my motor has stayed pretty cool, hottest right around 120F. The ESC has runa little hotter, as the fan will intermitently come one and off during the run for about 45 seconds. So it should be around 145F throughout the run. Not sure exactly what to say, as the ony difference in our setups are tires and chassis.

My LHS guy says the IR temp guns arn't accurate worth a crap and I need to spend the money on a freaking laser one. What say you? Suicide neil is saying I don't have enough voltage to move this big of a monster truck without generating alot of heat, any truth to that? I dunno what the total weight of this thing is. No, I have no holes in the body anywhere, I figured the body was so wide and open enough that airflow wouldn't be an issue, or so I thought. Crap, I really wanted to keep those screws in the endbell to keep dirt outa the motor but if its overheating it, that does me no good and I never had temp issues with drag brake on my first flux.

Damnit, I really do need a temp gun.... :no:

poppycock about the temp gun, just dont point them at refelctive surfaces..my cheap o duratrax one is within +/- 8degrees of a 400 dollar lazer one.. that the locals had at my home track

And those extra holes will do nothing meaningful to heat dissipation.

You mean for the motor?

Allright, i'll go place an order for that Duratrax gun right now, I gotta know what is going on with my truck so I don't fry the thing cause i'll be sad and cry....

NO CRYING ALLOWED :lol:

Just get that thing back out and do some more damn flips
Get us another new vid tommorow :whip:

I use this one and has always seemed pretty accurate.

Unless the fan is on all the time I wouldn't worry to much about the esc, the fan is doing it's job, just make sure the fan comes on at start up everytime so you know it's working. Also because your tires are slightly bigger and heavier I would have to recomend dropping a tooth or two on the pinion, that will definately help the esc, and may help the motor a bit too. I think the brushless MTs all come over geared out of the box, gearing for over 40 on 4s is a lot!

I did experience a hotter motor running those tires on my previous Flux build. They do weigh a lot more. They're around 320gm each, stock tires are about 250gm. So thats and extra 280gm of rotating mass all up or 28% more tire mass.

Unfortunately i didn't have a temp gun at the time so i can't quote temps. However i do know it wasn't so hot that i couldn't hold my finger on it and that was with 5mm chassis and LST shocks adding more weight.

I can't believe you don't have a tempgun yet. Measuring = knowing. I'm also using the Duratrax one and I feel it's pretty accurate.

I have been driving my Flux / Flux XL on 4S for over a year. Never had heating issues. Recently I purchased a set of HPI Terra Pins which are quite a bit bigger and heavier than the Mashers and BadLands which I usually run. I noticed immediately (I measure temps every minute when I change something on my car) that my set-up was running hotter onroad then normally offroad. So I dropped from a 20T to a 18T pinion and problem solved. I'm still running 18T, also with my other tires and can't really notice a lack of speed so far. Normally I'm at max 60c / 140F on both motor and ESC. When I'm solely jumping I'm at 45c / 120F.

I would just drop one or two teeth on the pinion and try again, AFTER you have your tempgun.

ps. My XL was lighter than the stock so that's not exactly even to your car which is probably a bit heavier than stock.

I have the Duratrax one and it works fine. But this looks pretty damn close. 60% off...

Up to 230*F Past that and your motor is cooked anyway....

With Stopwatch to time your runs. LOL

So far, im not too impressed with the XL conversion all around from my few drives with the truck. I may end up going back to stock Flux size if my tweaks on the XL chassis don't improve it. I think actually prefferred and had more fun with the Flux when it was twitchy and unstable due to the insane amount of power on a standard MT chassis.
