Official Erevo 1/8 scale center diff thread

[mistercrash]

The LST XXL diffs I got on ebay all had the Team Losi Heavy-Duty Differential Case which use metal thingies for the shafts of the spider gears. These diff cases are the same cases used for the Losi SmartDiff. The LST and LST2 diffs I worked with used the stock Team Losi diff case.

Oh I se what your talking about...the metal wedge inserts with the holes in them that hold the shafts of the spider gears. thanks!

First off i want to say that MC is a great person to deal with, he answered all my questions about the 1/8th scale CD and even gave me tips and help on installing it properly.

unfortunatly i dont have access to the machenery required to complete the 1/8th scale diff but would have jumped at the chance to make one myself if i did

I purchased the MC 1/8th Scale diff and he shipped it out the same day, it came just as pictured in this thread carbon fiber disk and all. The diff itself when i got to look at it up close is made extremely well, all of the cuts and modifications needed to make the diff are top notch!

Just incase you are on the fence about getting one... DO IT! this cd makes a huge difference in my opinion. on to the reveiw!

WOW!!!! this thing is awesome! i filled it with 50k only, since i really only run 4s geared 18/54 and this is how a CD should work! it unloads a tiny bit to the front and will only wheelie if i from almost a dead stop punch it. this cd makes the truck handle so much better when it comes to onsteer push since its not unloading to the front causing the truck to lift the nose up, slide and not grip the ground. you can also see the difference when going in a straight line, it makes the truck hug the ground and stay planted not wasting that valuable mamba power!

I'm glad i made the investment this CD it is a must if you like going to the track, im sure i will be able to turn much better and clear jumps easier since i wont be unloading motor power to the front. Next test will be to see how well it holds up to all the abuse of brushless over time and at the track but i can say that this thing is beefy and looks like it would out far far oulast a stock e-revo CD not to mention work 100x better

thanks again MC!

Thank you rrgirgis for those kind words. Just so everyone knows, I'm not starting a company or anything like that. Every part needed and how to modify them is listed in detail in these forums so anyone can make one for themselves. But if someone as very limited tools or they just don't have the time and they really would like a to have an 8th scale CD for their ERevo then I can make one for them.

[shaunjohnson]

ok, all the parts have arrived...time to make diff mk2
the first one i made from your instructions i tryed to use what i already had, didnt work so good.
but even so...that diff was pretty darn good!!

[shaunjohnson]

ooohhhh maaaannn!!
as linc would say "hand porn alert"
this new diff ive made to crash's specs....soooooo good!!!
i cant do backflips again! and it handels soooo much better!! can kick the tail out some

thanks for the simple design...you know the BB used to center the plastic gear onto the ground down ring gear...well i lost quite a lot of balls from that one when i managed to smash it
didn't matter though as long as the gear was centered.
filled it with 100k as i like wheelies and sending plenty of power to the rear.

[mistercrash]

Good stuff. This CD is what I would call the culmination of many ideas from a few people dating back to the first 8th scale CD ever made by CowboyRay. We all came up with something that is easy to make, easy to maintain, rock solid and easy to get parts for. Let's give ourselves a big round of applause.

[sjcrss]

Well said MC.......I agree.....it is a real simple and effective design.....I'm surprised traxxas did try to make a clone of it , kinda like your aluminum clutch disc.....

[Urgeoner]

Yes! I too made a CD usinh MC's designs, and it's been holding up! About 5 monthes now!

I'd love to make two of these for my revos but i lack the tools necessary and being a site work (construction rigging) i work very long hours (up to 70 a week) would realy love to be able to get the power down in my revos they certainly are so torquey it's not funny.

[isuck@rc]

honestly suprised mike hasn't jumped on this and started making them

[sjcrss]

I sent Mike the original design and plans when I first drew one up, and explained how to make one, basicly the same way I explained to MC, how to do it....I wish he could ..... but I think MC can make them for people, you will have to ask...

[mistercrash]

Yes until Mike decides to make them, I can make the CDs for the ERevo tranny.

[isuck@rc]

Thanks Ray, really appreciate it. I sent you a PM looks like 4 now though two other mates want them + the 2 for myself- hope you're making something on these though considering the price and what they are I think its a bargain.
Still feeling guilty at getting you to do it, love to do it myself but lack the tools and time.

Mate the carbon bulkhead ties i got off you nearly 6 months ago are still going strong too.

If you saw the tools I used to build mine you would fall over laughing. 1970's era bench grinder and 1950's era drill press. The key thing is getting the right drill bits, carbide. I'd like to say the spot annealing helped, but I have no baseline to compare it to.

Wasn't someone playing around with using a Kyosho plastic spur instead of the hardened steel spurs? How did that turn out?
