[HELP] 2s vs 3s Combo

[Big Tex]

so ive been debating for a while now what to do with my scx rig, my current setup is an ae-2, integy 35t, geared 87t/18t on a 2s nano tech 5000mah 60c lipo, and i like the speed, but i would like more torque, when i get too twisted up my motor gets hot and i would hateto burn up a motor out on the trail and have to swap it out.

also with such a huge pack it pisses me off because im ocd and i like everything even on both side of my rig, i cant run 2 packs in parallel because i would be adding POUNDS to my rig and i dont want that, plus i hate when it leans a bit to the left or teh right because the lipo shifts.

anyhow, i just picked up a sidewinder sv2 programmed for brushed motors and 200% drag brake, and 4 3s 2200 mah packs, now my question is how long will these smaller packs last in my rig with normal maybe 75% throttle peak but mostly low speed crawling? with my 2s packs i was getting nothing less than an 1 hour of run time then a slow decline in power, also what should my gearing be? the same 87t/18t..? 87t/16t..? or 18t/20t..?

You can run two 2200mah packs on the sliders in parallel. You'll want to gear down a bit going to 3s from 2s.

I would run the 2200 packs in saddle formation and go 87/16...you should get at least an hours run time maybe an hour and a half...depending on throttle use

[Big Tex]

so from 18t to a 16t on the pinion? im running wb8 driveshafts right now and i have yet to have one fail on me with a 12lb rig so that should show you how easy i am on the throttle lol very very light footed, so basically in saddle on the sliders then parallel on the connector on the esc? should i dial down my throttle percentage on my remote? i really dont wanna have to go MIP on my shafts, just want some extra wheel speed on the climbs and a little more torque on the rocks.

[allanon1965]

Yes on gear an saddle packs in parallel....run driveshafts till they twist

[Meatwad]

12lbs? Wb dshafts with 48p gearing? You, sir, have alot of throttle control

Normally I aim for 5:1-6:1 ratio at the spur/pinion, accounting for an axial drivetrain. Closer to 6 would probably be better for your electronics and that heavy of a rig.

lmao and when they doo i have at least 4 sets of shafts for backup

ha i really do, im more of a realistic crawler i dont like just soaring over obstacles, i like the technical side of scaling more than the speedy side.
so an 87t/15t combo? that would put me at just under 6:1 ratio.

To help the wb shafts to last longer. Fill the inside of the male shaft with a piece of plastic from a parts tree that fits in it snugly leave about 5 mm hanging out the end of it. Use silicone to hold it into the male end. My buddy did it to his wraith got 6+ months out of them running 3s and brushless.

ive heard of using all thread or a bolt with the head cutoff, do you know what part of the parts tree he used?

well do you want to upgrade your tranny gears and axle gears and c hubs and knuckles and cvd's? 3s imo is too much power for a scx10. try 2s on a good 27 turn motor. more power just seems to beat up the truck way faster. imo the intigy motors are not that great for crawlers. try a holms hobbies pro motor if you want a nice amount of power. right now i run 2s on a old 27 turn race motor i have had for a long time on 87t/16t gearing with pit bull tires and i feel like i have way more power than i need. my motor doesnt even have that much toque since it was built for top end and not bottom end.

My entire truck is bomb proof except for the plastic spur and wb shafts, purposely so that when something fails it's cheap and easily accessible.

As far as 3s I want to switch due to using smaller lighter packs and I plan to dial down my throttle on my remote maybe to 75% and reverse to 50%

[some87]

only problem with the 2200 3s packs is you might get about 30 minuts of run time. at least i know on my old comp rig i would get about 8 minutes max. as for the spur that is the best thing you can do is keep it plastic. you shouldnt have to dial down your throttle and reverse as long as your responsible with them know when to use the full amount of power. newer people tend to just punch it when they get into a bind and break lots of stuff that way.

That sounds reasonable, and I agree with you on he newer guys with no 1:1 trail experience that just fly through and over things. Ill be running the 2200s in parallel and have an extra pair of 2200s in my pack ready to swap out. If anything I can get 3300s or something a little bit bigger.

I run 2200 3s with a pro4 in my rock bouncer and get about an hour out of them.... WB shafts lasted 2 runs with wood dowling in them lol
