RC Diff Tuning Tips & Tricks Differentials Tekno EB48.4 Buggy

[@squeakygiant]

Front diff setup affects on and off power steering. On a smooth track, heavier front diff will give more on power steering, which is typically out of the corner (think both wheels clawing when the wheels are turned), but less off power steering (front wheels are more stuck together). Lighter front diff will more off power steering, that is typically less turning out of a corner when on the power, but more steering into a corner and mid corner when you are typically off the power. Lighter front diff will also give better bump control (as it frees the front wheels to act more independently when hitting a series of bumps).

@CJ Hello Mr Moto, hope you're doing well. I also have video and pics from 2009 of my daughter at that age, testing the shocks on my Jammin' X2 nitro Truggy🥰 I sold my 48.4 after a couple of hard years on her, and now have the eb-2.0. My buddy Galen jumped on the new 2.1 and loves it, but says it's not really THAT much better than the 48.4. So after driving it I liked it too, but for the money, I decided to go with my 2.0 again this year since it's not really even had a full racing season in it. Sorry I didn't (until tonight), see your response to my "front diff" post (3 years ago!), but I appreciate you taking the time. Have a great season!

I run 775 and more recently I have been running 773 in an Mbx7r eco. My track is a loose river bottom slit, and low, to medium grip. I also use the underdrive in the rear, to give more pivot. Another important aspect of Corning is camber and tow... I have always ran with a lot of front tow out, it gives the car more stability exiting corners and good off throttle steering. This was a tip a pro driver gave me a year ago, and since, I always run alot of tow. Great video! I'm not an expert either, but always learning!

I have tried toe out and really like the wheels strait but I know that’s very popular. I think sometimes toe out gives you more steering and others less. Thanks so much for watching!

Your honesty is rare and cool, one point is i want to raise is that a diff split the RPM into 2, and each side gets the full RPM, so the sum of the two output sides is actually the input RPM times 2, so if the diff is outputting all to one side, this side will rotate at double the input RPM, so on a 4wd car, if you "diff out" all onto one wheel, this wheel passes 2 diffs, so it actually rotates at 4x the motor RPM. You can test and see that if you hold 3 wheels and full throttle onto 1 wheel, this wheel will balloon like crazy, and if all the wheels turns and you full throttle, they will balloon much less.

[@CJMoto]

Got ya I’ll clarify that in another video. So two wheels diff out then 2x motor RPM. 4 wheels diff out 4x motor RPM. Thanks got the input sir!

[@yonicozac]

CJ Moto actually if ONE wheel diffs out, he gets 4x RPM

[@stefengullicksen38]

Interesting and honest, Thanks

[@marmormik1]

If your drag racing’ I lock the front diff so the front is pulling the car straight.

[@HL-OOI]

Basically it’s all personal preference base on track conditions..I run 10/10/5 on turf on my sct..👍🏻 maybe will try up the center diff for more torque to easily clear the cross over jumps..

[@CJMoto]

Yea I find that if I got thick in the center the car becomes very hard to drive and I have trouble laying down the traction properly.

[@kennethjeffries5022]

At the track I would change the Front or Rear diff to try different oils but its far from the easyiest to get to them on the E817 . I Usually run 5,7,3 im not a crazy man on the trigger but not the smoothest . 5K in the center if its really loose for sure much easier to drive il say. Inless the track get pretty grippy and blue groove almost that's the only time il use a harder compound tire or go with heavyer diff oil Front or Rear .

[@CJMoto]

Yea I am interested to see how the 5 feels on the track for sure.

Cheers

CJ...... The front diff does the same thing the others do. Other than loose track/high bite track differences (loose track with heavy front diff will be less stable, more wandering),the front only effects turning behavior. If you want more ON power steering (or "pulling" from the front wheels, you go heavier (up to a point). The "outside" wheel in the turn will of course haves MORE grip on that turn. IOW, think of the front diff as doing to the left and right front wheels EXACTLY what the center diff does to the front/rear wheel. So when your turning the inside wheel will always tend to "diff out" at least some (just like fr./r.)

[@CJMoto]

Thank you that’s good info I am starting to get it more do you lean towards a heavier front diff? I guess it all depends on track conditions. Ok running 6-6-3 in buggy and 10-15-7 in truggy.

[@kennethjeffries5022]

I can guess why nobody really uses 3k in the Rear diff on Tekno buggys because they have tons of rotation and steering to much actually lol I used to run the 1st ed 4WD SCT.

[@moremagiic]

Using thicker oil will make the car turn more on power, out of the corner, and accelerate faster. The car will turn less into the corner, as off power steering is reduced. It will feel more stable, and can be easier to drive in bumps. If the car is twitchy and feels inconsistent on a rough track, a good idea is to try a thicker front diff. A thinner front oil will have the opposite effect, less on power steering, more off power steering, less stability. Usually the oils used in the front diff range from 3000-15000. 5000-7000 is a safe bet on all tracks, and that’s what I use most of the time when I’m using a standard front diff

[@CJMoto]

How do you feel about 6-5-3?

[@moremagiic]

CJ Moto I run Mugen so my standard setup is 5-7-3. But I run on a bumpy loose off-road track. So it’s really all down to your personal feel and track. Also the car that you drive can be better w thicker or lighter oils. So that question is a little hard to answer w no other information

[@rc3151]

...unless your a dirty alley rat. Then lock the rear and light fluid on the front. Ps good video enjoyed the insight.

[@caysonbrixton5015]

i know it is kinda randomly asking but does anyone know of a good site to watch new tv shows online?

[@wellsbenedict3333]

@Cayson Brixton try FlixZone. You can find it on google =)
