Concerned about new Savage Flux running a bit warm on test drive

Allright, looking for some input from the castle guys on my temperature concerns with my new Flux on its first test drive. My new project, "Frostbyte II" with a new Savage Flux is nearing completion and I FINALLY got to take it on a test run today to see how everything performs.

This was the following setup during my 10-12 min outside, concrete run.

Gearing: Stock 20/44
Slipper pad: Cranked down tight
Lipos: Turnigy 5200mha 30c-40c hardcase
Blur settings: 10% punch control, 20% brake, no drag brake, 25% reverse, 3.5v cutoff
Diffs: 50k oil front and rear

The truck is on standard HPI GT-2 tires with white dish wheels. It's also on an extended FLM TVP chassis with HPI extended axles. The endbell of the Tork motor has also been sealed up with screws to minimize dirt intake.

I went outside a short time ago in around 90 degree temps and gave the Flux some trial runs on the black concrete with no shell on. It was basic, straight speed runs with a variety of throttle usage from full on power to slow acceleration along with testing the vehicle's ability to wheelie via both a rolling and standing start. Within a few minutes, I stopped and checked the temps of the motor and ESC and they seemed reasonable, so I continued a few more speed and wheelie runs on the concrete along with a fair amount of braking.

Around the 5-7 minute mark, I checked the temps again and I noticed the motor housing was getting pretty warm all around. I could keep my finger on it without discomfort. The ESC was also pretty warm on the outside. I did some short wheelie, full throttle blips and checked again. This time, the ESC fan was kicked on and ran for a few seconds before shutting off, the bullet connectors were hot to the touch and the motor housing was now pretty warm, warmer then I remember my first Flux motor running.

Unfortuantly, I do not have a temp gun, so I am going by feeling for temperature readings. I again did a few more laps on the concrete and once again, the ESC fan was running when I brought it in again and the motor definently had a singy feeling heat quality to it. With that, I shut it down, brought it inside and also found the Lipo's were slightly warm to touch once I removed them.

It's been awhile since I drove my first Flux so I'm no longer familiar with how my temps should be, especially with my current build. Could I be increasing motor temps from sealing the endbell? Is that still considered "safe" on sealing the endbell like you told me last year? Is the XL chassis and wide axle putting that much more load on the whole system? The entire tranny felt very smooth all around with no binding that I could feel anywhere.

Any suggestions or incite Patrick to either confirm or deny my temp worries? Thanks again.

Spend the 20 dollars and get a temp gun to know whats going on with your 1500 dollar truck...

Esc fan comes on at 150 which is fine...

If you can hold your finger on the motor for 3secs its fine but i agree get a temp gun

If you can hold your finger to it without discomfort, you are well within the "normal" range.

If your finger sizzles, and you scream and yell and blisters appear on your fingers, then you are probably running it a little too hard.

Seriously, the motor is fine to temperatures that would cause you a lot of discomfort... The main magnets in the 2200 motor (the HPI flux is based on the 2200) are good to 170C-180C, which is about a 120-140C case temp. The windings are also rated to 180C, and the main wires are rated to 300C.

So no worries at all.

that's 250F btw

Patrick told me to tell you to get a temp gun before you bother him more. He's busy with the MMMXL

No he didn't....





Did he?



I get the message, I just placed at an order at amain for a duratrax temp gun, happy now?

No, because you'll still find things to moan and hand wring over.

I may not have a direct line to Jesus, but I got one to PdC.

Actually, not so much a direct line to PdC, but I do have Chris on the speed dial, and he's got a direct line to PdC, and that's got to count for something.
Well, maybe not a direct line or the speed dial exactly, perhaps he just knows the extension..., but really that's beside the point here...

Look. I'm sure if I asked Jesus, even he would say to go get a temp gun if he has not miracled one to your butt already. However the hand would be preferable. Jesus may have turned turn water into wine, but he never built a HVMMMXLOMGWTFBBQ, and that is far more useful frankly, so please leave the man be until you get your temp gun and we've exhausted every option to your problem, which I'm quite certain will be not much of a problem. Failing that, then we call Jesus. Then Santa. Then finally BA Baracas, Micheal Knight, Thomas Magnum and Angus McGuyver.
Don't worry, we will get to the bottom of it. Its what we do, and we're professionals.

Then, I am sorry, but why Castle team recommand to keep the temp below 170°F for the motor if it can handle easily more than 200°F ??? Because running the motor at thoses temps mean that it's pushing too hard the Mamba ESC ??? Or it's for the black plastic wires maintainer ?? Or another thing that can melt internaly ?

[nitrostarter]

Get a temp gun!

*sigh*...... another thing to buy

20 now or 170 later if and when you melt down a major component....

I know, guess i'll place another order from Amain...
