I'm working on a new setup for Stock with the 415. Trying to get more rotation in the car for certain turns at my track. This weekend we are having our Region 3 Race at our local track. And I'm defending champ... Only problem is that I've been running the 415 in stock and it's been the faster car for me (as opposed to my Yokomo SD). But now with some testing.. I just shaved 4 seconds off my 415's best time with my SD (using same motor, batteries, and tires). So now it's the faster car.. So I gotta go to work on a setup if I am to race the 415... drats... Gonna try out a shorter wheel base than normal. Plus a few other things...

Any body mess with different spur sizes? Gonna try out a 96spur. Just curious if anyone has noticed any performance differences with different sizes.

Hi,

Need help with foam tire setup on carpet using the dbl oneways. Anybody here tried this out?

I know it's gonna be hard to run the car using the dual oneways, but I have not finished building the diff yet and the locked center pulley. I would need the setup just in case building the front diff and the center doesnt work out.

Default Re: foam setup

Here's a post from Martin...

For foam racing I made up a front diff and locked the center one-way eventually. I started with the double one-way, but it was hard to be consistent, but with 19 turn it is not too bad wth the double oneways.

Here is a base setup

Front

Springs : Assoc purple
swaybar : Tamiya Blue
Shock Oil : Assoc 70
Caster : 4 degrees
Roll Center : (Moderate) Upper links have no spacers. Other than the anit-dive no additional spacers under the hinge pin blocks.
Anti-dive : 1mm spacer under rear hinge pin block
wheelbase : all the way to the back
camber : -1.5 on front left , -1 on front right
Tire : Speedmind 35/52 shore

Rear

Springs : Assoc Copper
Swaybar : none
Shock Oil : Assoc 50
Anti-squat : none
Roll center : (low) Links have no spacers on inner pivot ball. Used inner hole on rear upright. Hinge pin blocks both flat on chassis - i.e. no spacers. You might want to try a 1mm spacer under the inner pivot ball on upper link to make the rear a little more stable.
Rear Toe In : Total 1.5 to 2.0 Since it is a double one-way you may even want to try 2.5 it the car is too twitchy for you. I liked 2.0 with the double one-way and 1.5 with no one-ways.
camber : -2.5 on rear left, -2 on rear right.
wheelbase : all the way tot he back
tire : speedmind 35 shore.

Depending on the track I will run slightly more camber on the left side of the car. i.e. most tracks seem to have their highest speed corners turning right. So to ge a more even tire wear I add just a little bit more (maybe .5 degree) camber on the left side.

A question for those running the Hybrid front Ball Diff on the 415 (yokomo bits):

How do I get the F201 Universal Shaft to fit onto the 415 Outdrive? The small steel bit that has the grub screw in it is too big to fit the dog bone part of the universal

Do I require the whole F201 Universal including outdrives?

Lycan, i was using a conglomeration of Yokomo cvds when i ran the diff... kind of a pain in the rear. if you catch Suradaj on here, as i remember he was using the F201's drives. the outdrive isnt even close. are the ones you got Tamiya? i wonder how other manufacturers would fit...

Will Tamiya be releasing an OEM part that will end the hassle to convert to full 4wd? I'm just not a big fan of using custom done work or hunting down parts from various manufacturers.

Yes and no... Tamiya is releasing a locked center pulley set and should be availabe within a couple of months:

Item 53708 TRF415 Direct Center Pulley

As for a front diff, you can either look into getting Jurgen diff halves or piece-meal one from other kits. If you want to run a spool, you can pick up a Speedtech spool or a Jurgen spool.
