OVER GEARING “The CHEAPEST Traxxas Slash” As HIGH As It Can GO!! Is This GEARING TOO HIGH???

[@daveskafenstermacher9484]

Thank you so much for going every small step of the way with the upgrades on this platform. As a beginner looking to choose their first RC, I really am interested in how much I REALLY need to spend on upgrades in order to get the most fun out of it. Extremely helpful!

[@RCKnockout]

[@harrychattaway1556]

Man i had an over powered brushless 2wd slash that was absolutely wild, needed wheel weights for the front and did backflips on half throttle without a wheelie bar+weights. Blew through beadlock tires like crazy

[@RCKnockout]

Yeah the 2wd Slash is an awesome platform….upgrade the power a bit and they’re absolutely mad lol

[@RC_Trailblazers]

You can run a M1 36 spur and M1 32 pinion it fits with just about a 1 to 1 ratio. The vxl motor doesn't have enough juice to push it on 3s 120c 6000mah battery. Only gets to about 58mph before the motor starts getting extremely hot battery gets pretty warm to.

[@RCKnockout]

Good to know, thanks!

[@kevinloose9939]

Changed out gears and pinion about a week ago. I think I was told to be careful with starts and stops. Driving at a a more constant speed it better.

[@RCKnockout]

Yeah high gearing definitely puts a strain on the system

[@Bhase425]

If You put a 76 tooth spur gear on it you'll be able to put on a bigger pinion if you wanted and The spur gear might even help on the acceleration I learned putting on a 25 tooth with 90t spur made my car acceleration really bad and as soon as I put on a 86 tooth sper the acceleration was much more acceptable and even helped with the speed motor didn't like it too much but that's to be expected But I know it will probably make it go even faster I have got a Traxxas/two-wheel and it's about maybe 10 or 11 years old same transmission and gears since day one and they're still running strong and smooth I did have to decrease the gears and put new grease on them but that's about it

[@jeremybethea4320]

Get the 36t mod 1 spur and throw a 24t pinion and watch the difference in speed 😎👍

[@lbombrattler7655]

I run 33 pinion on 64 to 76 spur. Well over 100mph if it doesn't start flying first. It's crazy

[@truckerboy211]

Does that spring have to be completey straight? Mine wont go back on all the straight and it seems like its not right. Just wondering if thats gonna hurt anything?

[@RCKnockout]

No that shouldn’t make a difference

[@AZGT350]

Question, when I went to re-gear mine, I had a black plastic plate between the motor and mounting plate where the two flat top Allen screw screws sit on. On the plate I removed there are raised areas that prohibit left/right movement of the motor allowing a larger metal gear to be stalled. Can this plate be removed and than mount the motor directly to the fixed plate with the two black flat top Allen screws. Thx

[@RCKnockout]

Yeah you’ve gotta remove the plastic plate to adjust the gearing….the whole purpose of the plate is so beginners don’t have to mess with the gear mesh….but it only puts it in the exact right gear mesh position for the stock gearing….anything different it has to be removed

Ennek így nem sok értelme van. Felesleges roncsolása a váltóháznak. Áttétel táblázatban simán látható, hogy kisebb pinion és kissebb pl 76 os spur kerékkel is el lehet érni hosszú áttétel. Pl 21-90 =17-86 és még a lend tömeg is kisebb. Ráadásul a 12 t kefés motor is jobban melegszik a nagyobb terheléssel. 8.4v nál többel sincs értelme tápolni mert csak hővé alakul az energia. Terheletlenűl szépen ballonosodik a kerék. A magas fordulatszám miadt, de talajon már nem képes ezt a fordulatot átadni, ami a motor tulmelegedéséhez vezet a le nem adott fordulat/volt teljesítmény felesleg miadt. Tapasztalatom szerint 25/83 az max áttétel titán 12 moorral plussz hűtővel lipo 2s akkuval. Ezt még viszonylag jől tűri hajtás lánc. 3:4 fordulat nyitással a csúszó kuplungon.
