Default RE Losi SCTE RTR loses power after 7/8 minutes

The heatsink and ESC were hot. The batteries were three different brand LiPo 2 cell, all good. Voltages were fine. Once the truck's components cooled the batteries powered the model for another 7-8 minutes.

I put the truck on the workbench tonight (work was very busy all week and I never received a chance to do so until today). I noticed that the ESC fan stops turning if I tap it. I'm guessing the RTR's ESC fan is getting knocked around and stalling, and the ESC is overheating.

The Losi SCTE RTR shipped with a stock ESC/motor combination. Should I replace only the fan or the fan and ESC. Or, since my son will soon be running a six-race points schedule, should I just upgrade and purchase an SCT ESC/motor combo?

Many thanks.

What batteries did you use, what were the voltages before&after?

The truck runs fine after it cools, even with the same battery.

I see your update from 8/2, I would change the fan and see what happens.

Default LOSI SCTE Diff Rebuilding Question

Hey Guys --- thanks for all the help so far on this truck! Expecting the 1.0 Roller (new) on Monday & ordered:

3 x HD Diff Cases
2 x Front/Rear HD Lightened Outdrives
1 x Center HD Lightened Outdrives
3 x Diff Gears/Hardware sets
2x HPI 2.5x12mm screws everyone recommends
Even front and rear gear boxes

With the above, and diff oil/grease of course, can I FULLY build each of these "HD" diffs off the truck THEN just swap them out fully assembled with the outdrives on and all???

Thanks - I may not be racing right away with it so I may just keep the grease in there and run it for a bit. But would like to change to oil/HD Cases & Outdrives for durability.

Also, am I hearing right that you don't need those tiny metal washers with these new HD cases? Just hoping there is good exploded view of the diff assembly!

The SCTE 2.0 diff cup does not need the shims. I assume if you pulled the PDF for the manual on the 2.0 it would give you the exploded view you need.

As for what to put in the diffs, I would never build one with grease, you are better off tune it for your traction you are on and how you want to come out of the turns.

Sounds good - I will use 5k 5k and 3k respectively

You will also need
3x Losi Differential Seals w/Gasket & Hardware for the pins that attach the sun gear to the outdrive, 1x spur gear and one each of the front and rear ring and pinion set.

I ordered 3 x Losi Differential Gear Set w/Hardware (Ten-T) (LOSB3569)...wont that have the pins & the ring/pinion for front/rear? Do you know the part # for the Spur gear? Is that just 1 item? Looks like its a different Spur for the Front/center and rear?

If you are not racing right away, then good idea to not bother switching out everything just yet.

Another thing I would advise is wait to change out the HD Lightened Outdrives. I also bought the HD stuff when I got my new SCTE, but decided to use-up the existing outdrives first. Over 1.5 years of light racing (once or twice per month) and they are finally starting to get to the point where I want to change them next rebuild... But hey, I got an extra year out of them than I would have had I changed them right away...

AFAIK losb3569 only has the internal diff gears, not the ring gears. they also only contain the cross pins and not the outdrive pins.
Stock spur is losb3436, front ring gear&pinion is losb3571, rear is losb3572.
Ring gears are somewhat similar to the spur, but both are metal and crown gears.

I just rebuilt my diffs with HD cases, new internals & 5/5/3 oil. They're STILL leaking. I rebuilt the rear one AGAIN, didn't even run the truck, and there are now oily spots on the bottom of the case, which I noticed when I took off my rear bumper. I followed Adam Drake's rebuild video, making sure there wasn't too much oil in the housing...
I even picked up the HPI screws, which unlike the crap Losi screws, you can actually cinch all the way down.

What am I doing wrong?

Don't take out the large washer behind the sun gears on the Ten diff like they do on the 8ight diff. If you are running std diff cases (not the updated HD ones) you need to bond the metal insert into both sides of the diff case.

Or just get the HD diff cases.

I have the HD diff cases, all around. Kept the washer in, no shims used. Still leaking.

That is odd. The HD diffs have been GREAT with all of my experience and have not leaked since I started using those. Where are they leaking from can you tell? The gasket or the outdrives?
