I think they are steel. I just replaced them with carbide ones last week. Really smooth after a couple of races.

Weekend---- for blank set up sheets they come with the car. You can also go to the Japanese site and they have a link ther for the blank sheet. For TRF sheets there is a couple of setups here and there are set-ups from Yama Yama on the same page as the blank sheet

I haven't rebuilt my diff since I got the car back in uhh February. And it's still smooth. Of course I've only ran Stock with it. I'd like to try some carbides though.

You can also find setups on RCZone.net.

Is the 415 diff different to the EVO3 diff beside dimensions?

That´s the only problem I have with the EVO3. Diff don´t last longer than about 10 runs.

I don't think I've had that trouble when I had my Evo 3... of course I did have carbides in that diff. Plus I make sure I pack my thrust bearing FULL with grease. Normally I use AE black grease and make sure it is PACKED. This time I don't remember if it was AE Black or the Tamiya antiwear grease. More than likely AE.

I think the only times I had trouble with the Evo3 diff was in Mod. But I'm not entirely sure as it's been along time.

Hi Guys,

I just finished building my 415

Pretty happy with the results. Looks cool.

I was hunting around the internet for photo's before my purchase and noticed these:

http://www.rczone.net/modules.php?na...rticle&sid=454

I was comparing my car with Surikarn's today and I was interesting in how he's changed the inside top turnbuckle mounts on the shock towers. Anyone have a theory on why he would do this?

Was it a prototype of the 415 where they were finding the perfect/best position inward/outward from the shock tower?

Cheers
Lycan

ps. Anyone know where to get the rear uprights he also used?

Default Surikan's Front Upper Links

Lycan

I looked at the pics of Surikan's car. By running the front upper links so that they attach to the front shock tower this raises the inside of the link, which creates a lower roll center. This lower roll center in the front will give more steering. He also flipped over the rear hing pin block at the front of the car. This gives him some kick-up and also further lowers the front roll center. So he was looking for a lot of steering. He did a similar thing with the rear upper links (i.e low roll center). The rear does not appear to be setup to allow as much roll as the front, but it is close. My guess is that the surface he ran on did not have a lot of grip, so he went with a very low roll center in the front and a moderately low roll center in the rear to get some steering and overall lateral grip in the car.

Hi!

The 415 has not so much grip with the A-Blocks Surikarn used. I drove it with A-Blocks, too. The car has not the grip as with the D-Blocks.

oh, sorry, one more thing

The suspension arms for the 415 are the same as the 414?

Cheers

The Suspension-blocks are new. They are not the same as the evoIII I thought first time. The rollcenter at the evoIII is a little bit higher as at the 415.

Input re Spool & Diff for 415

Currently in the process of deciding w/c one to get...spool or diff for the kit. Three things I'm taking into consideration in w/c one to get: price, maintenance and effeciency of the setup. I know w/ the spool, I only need to get the spool, another locked center pulley and center shaft w/c will probably cost around $50.00 (give or take). While w/ the diff, I need to buy Yok parts, Tam diff pulley (rear), diff balls (thinking going carbide), locked center pulley, center shaft & F201 univ. (pair) or just replace the orig steel univ. from the kit w/ Tobee Craft F201 light weight alu univ. bones (w/c I'm not sure if I could use it w/ the orig hardware from the 415 axles). With the diff, I believe it will cost about $30-40 more.

Need input which would be the better config? The track I normally run my cars is not suitable for front/center one-way.

Thanks for any input you may have.
(P.S. I have never driven my car w/a front spool before and I know the set-up may be different than from running with a front diff).
