I have a hpi savage flux with mamba monster 2 esc. 2200k monster brushless motor and two 3c 5000mah 25c lipos in series. On a full charge I'm getting tops 15 min of run time then it shuts off I guess cause it's to hott cause I'll let it sit for five min and I'll get a min or two more. Is that normal?

Ya could be getting hot, do ya have a temp meter to measure it with.... it also could be the batteries not holding up to the discharge rate you are pulling out of them and this is causing it to go into LiPo cutoff stopping the truck until the batteries catch up, what batteries are you running and another thing to check out is drivetrain drag causing more amp draw that you need.....

just a handheld temp checking infrared thermometer, can get em on e bay, I would be checking temp on the motor and the esc heatsink....
drag can be alot of things, wheels cranked down too tightly, dirty or worn bearings, or stuff caught in the drivetrain causing drag....and the bigger the tires are the more they increase the gear ratio which could be gearing the motor too high causing excessive heat in the entire system....

That is what I mean by temp gun...

most likely would be geared too high by what you have posted so far, gear down the pinion by a couple teeth and see how it does.... That is as long as there is no binding in the drive system....

only way to know what pinion is on it is to count the teeth, looks like HPI includes a 20 as stock so start there and see how it goes..... if you don't have a manual you can download one at HPI's site...
here are the links to all the manuals for the flux

You are Welcome, hope it all works out for you with the truck......
Sadly it seems most all the knowlegeable guys who used to come here have stopped for a variety of reasons...... I don't know enough about the Flux to be much more help...
You can try PM'ing guys like frddyj or some of the other authors on the flux threads and possibly one of them may offer more insight to help you out a bit more....

The slipper clutch is one of many ways to help jarring hits from going through the drive train. It also lets you tune when the power gets applied to the wheels.
The noise could be the gear mesh between your spur and motor gear.

X is right the slipper is there to have a give point in the drivetrain so there is less chance of stripping gears and such... going from forward to reverse or vice versa can make for some fun action but it is also very hard on gears and related parts, as for which pads you have, if you have packaging for them we can probably look them up and see, but I do know there is a ceramic one out there that is pretty good....
