Mojave EXB lipo discharger ;-)

[ItAintAtoy]

I really needed another way to discharge some 3S/4S lipo's
Mojave has been on my list for quite a while, I thought I might as well make a build log, nothing fancy though, just the usual recipy for a new RC.

Parts list:
- Obligatory new car, with the widely coveted new-car-smell.
- Power plant and transmitter/receiver: hand-me-downs from the Kraton 8S
-> Spektrum 1250kV 4685 motor (previous gen with 5mm toothpick-strength shaft)
-> Spektrum 160A ESC
-> DX3 transmitter with SR6110AT receiver
- Servo: el-cheapo from the spare bin: DS Servo DS3235 Pro (https://nl.aliexpress.com/item/32702835900.html?spm=a2g0z.12010612.8148356.1.3fe17523WqKUI8) we'll see how it holds
- 24t pinion 5mm bore, mod1 safe-D
- M2C extended hubs (https://m2cracing.net/arrma/495-m2c-3160-arrma-17mm-hub-extenders.html)
- Proline Badlands 3.8 (https://www.prolineracing.com/tires/badlands-3.8-all-terrain-tires-mounted-raid.asp)

1st up prep-work and some installation:
- opened up the diffs, all 3 got the LSD-plates, rear is configured for minimum effect, center and front for maximum effect
- replaced stock diff oil with 50/250/20k front/center/rear for now, I'll need some testing to find out what oil weights and LSD-config suits me best
- motor fits easily, stuffed some heavy-duty packaging foam under the rear, maybe it helps to absorb the bad landings
- ESC needed a shave, bit too wide to clear the upper motor lead
- servo is a direct fit
- plenty of room in the receiver box for excess cables
- toughened up the body posts, again the packaging foam

This seems like the only rational, reasonable and responsible way to discharge all those dangerous lipos. You crack on mate, you're making the world a safer place

I was confused at first but am loving it now. How many times have I said "If you are getting badlands get the MX version, otherwise they are dboots backflip"

Well played, Sir.

Discharging Lipos was also my main reason for buying a Vorteks a few weeks ago.

I think you may find those diff weights to be a little stiff with the LSD. The LSD design really does a lot to multiply the viscosity. Just a heads-up, you'll know what you like when it comes to handling better than I would, and terrain makes all the difference. I've been running 20k/200k/10k, max/max/none and I think the center is overly rigid. I plan to try plates in the rear with 10k next. Some people like a flippy locked-out truck, but I thought it was faster, more controllable, and better in the corners before I went heavier in the center.

Thanks for the hint , I'll be looking for a balance between controllability and deliberate oversteer.
Will keep you posted what setup I end up with after some 6S/8S runs.

Haven't had much time, so only small update this time:
- set endpoints
- checked ESC settings and bind/calibrate, it has been on a shelf for a while
- removed the sliding top part of the battery tray to make room for hardcase 4S lipos
- added an extra velcro strap to compensate for losing the top part of the tray
- replaced stock wheel hubs with M2C extended hubs
- adjusted the droop screws to limit the travel
- still experimenting with ride height and suspension setup, I don't wanna lose the plushness the Mojave is known for, but I do feel I need to stiffen things up a bit, the 8S electronics and lipos are adding to the weight
- trimmed the body and front bumper a bit to accomodate for the bigger Badlands, should trim some more but for now I'm gonna keep it from rubbing by moving the body up a little
- had to drill some extra holes in the body posts to get the body a bit higher

Time flies when you're having fun, so much I forget to take pictures.
Next time I'll post some more though...

The weather outside is sh#t, raining 24/7.
What better time to do a sh#tty job, drywalltaping the body, at least some bits in the rear.
During my test runs I noticed this baby does complete backflips while rolling, without flooring the throttle for 100%.
So off course it's booty is bound to get cracked.
Automotive goop arrives in a few days to apply 1st coating, forecast for the next days is sh#tty weather...

I drywall taped and shoe goo my fazon body yesterday (front porch because the moment I got out it started raining)

Mojave has been on my list for quite a while, I thought I might as well make a build log, nothing fancy though, just the usual recipy for a new RC.

Parts list:
- Obligatory new car, with the widely coveted new-car-smell.
- Power plant and transmitter/receiver: hand-me-downs from the Kraton 8S
-> Spektrum 1250kV 4685 motor (previous gen with 5mm toothpick-strength shaft)
-> Spektrum 160A ESC
-> DX3 transmitter with SR6110AT receiver
- Servo: el-cheapo from the spare bin: DS Servo DS3235 Pro (https://nl.aliexpress.com/item/32702835900.html?spm=a2g0z.12010612.8148356.1.3fe17523WqKUI8) we'll see how it holds
- 24t pinion 5mm bore, mod1 safe-D
- M2C extended hubs (https://m2cracing.net/arrma/495-m2c-3160-arrma-17mm-hub-extenders.html)
- Proline Badlands 3.8 (https://www.prolineracing.com/tires/badlands-3.8-all-terrain-tires-mounted-raid.asp)

1st up prep-work and some installation:
- opened up the diffs, all 3 got the LSD-plates, rear is configured for minimum effect, center and front for maximum effect
- replaced stock diff oil with 50/250/20k front/center/rear for now, I'll need some testing to find out what oil weights and LSD-config suits me best
- motor fits easily, stuffed some heavy-duty packaging foam under the rear, maybe it helps to absorb the bad landings
- ESC needed a shave, bit too wide to clear the upper motor lead
- servo is a direct fit
- plenty of room in the receiver box for excess cables
- toughened up the body posts, again the packaging foam

Here is a great way to discharge Lipos. Good price, made just for discharging. Chargers are not very effective at discharging, justlook at the specs.
