Jeremy Mcguigan is a team driver, and does builds VERY affordable. Might want to reach out to him on FB.

F R
645 1008
39% 61%

Skipped squat induced CG changes and if the tires can take that 1g of acceleration (a bit lower transfer but remember we run anti squat so no big deal, the tires are the big deal but I think on upwards of low traction this info is solid provided the very scientific weighting method by DG Designs). This only happens for the numbers shared by DG!

@AntH3000 and @Krio, you seem knowledgeable, I like that. Always remember the car isn't static during racing

@Tekno, if you want me to keep spreading your secrets send free stuff to me. Just kidding!

Under acceleration on carpet this distribution is great, but on corner entry and mid corner I'm not convinced based upon the tyre width offset front / rear. Nice to see those figures on vertical wheel forces under acceleration.

Any plans to develop something this for the EB410?

Was looking at Teknos web site and they only have the 81T spur gear. Is someone making a smaller one for 13.5 or will we need to use a 28 - 30 pinion?

70 and 76 are options that have yet to be released, it appears.

Any ETA on the optional spur gears? I thought they'd come along with the other optional parts on Tekno's website? Really don't wanna use the stock spur for 13.5 if I can help it lol

70T spur should be coming. But you can get to the right FDR with the 81t for 13.5 class. Internal ratio is 2.5 if you want to do the math.

I know Tito is running a 30t pinion on his for 13.5t

yeah guys, not all of the parts, both standard and option, are listed yet. I know a lot of guys are looking for the servo horns and spurs (Myself included). I've been told you can fit up to a 34 tooth pinion with the kit spur. In order to get the recommended starting gearing, you would run either a 29 or 30, so you can see you'll still have a lot of room to adjust.

Personally I plan on just building an entire 2nd center diff with the 70t spur when it comes in stock.

Also I believe the Ruddog YZ2 servo horn works. It's not exact, but it's close.

Not sure what servo you are using however the servo horn that came with my Protek 160T servo worked perfectly for the LP setup..

The factory plastic one stripped out on the second battery pack. Was going to get the Tekno one when they came out but then another driver let me know the Protek one worked perfectly..

I'm staring at time..lol. I can build it for you if you don't find any soon. It would be at a pro level.

There is not much room for a fan with the stock mount when you run 81t spur and 30t pinion.

If you can't wait its probably best to get the carbon fiber top plate/fan mount if running a 81t spur/30t pinion with your 13.5 motors. But, honestly I would rather run a side mounted fan so I am getting ansi for that smaller spur gear!

You do get a little more room with a mod motor cause you can run a smaller pinion, so side mounted fan works in this case.
