From what I have been told, the Associated big wheels are wider than the others which would make the tire flatter. I have not confirmed this nor have I tried them.

Hey All, hope you are all having a nice thanksgiving holiday (I know it's early, but I'm ready for a long weekend already)

I've just upgrade my servo to the Futaba 9352HV which I am also running in my D413. It's a fricking monster servo. Unfortunately the ears are spaced a little "higher" than my savox so it doesn't reach the holes unless I use a spacer. I'm guessing some of you guys are also runnign this servo so I'm wonder what you are using for spacers? I think I saw some avid carbon fber crazyness....

Also, do you guys use the rubber mounts on the ears or do you just use the bare ears?
Pics are awesome too. Thanks in advance!

Dave

Bare ears with washers.

I'm guessing you'll have to grind some clearance in the underside of the front brace that goes above the servo. There is very little clearance for a standard size servo. I run the Losi aluminum servo arm with a locking nut and had to grind just a touch of clearance for it.

Be sure to check the manual for proper front to rear spacing. You measure the servo and shim it accordingly.

@oPaulo - What servo are you using? I'm also using the TLR servo horn with a locknut and didn't have to grind for clearance with my old servo. It should travel in the same area with the new servo given the front to rear alignment is the same.

Are you using spacers behind the servo ears in between the servo mounts and ears? if so how much?

I ended up moving my battery pack back one space and also pushing my ESC and receiver back a little allowing me to mount the Futaba servo with no spacers.

The futaba 9252HV servo is about 3-4 grams heavier than my savox 1258. Just FYI, especially for those wanting more weight up front.

Holy crap my stuff is filthy with the flash on!! That's what non stop racing does I guess.

You have to measure the servo to determine the spacer.
The Savox 1258 didn't need one.
Radiopost red needs 1mm
Reedy RS1206 gets 2mm
It's in the manual.

Oh I ground this spot at full left lock. The nut was touching it. The other spot was for the Yaiba steering rack. The arms are thicker and made clearance issues.
Still, I don't have any room to space a servo up off the chassis. The rod end would rub at center point.

The aluminum front arm mount puts a stop to this.....


Highly recommended. Don't think your plastic one is tweaked? Check it. Check it good. Check it every time you catch a pipe.

Been looking a lot lately at different platforms. 22 3.0 has really caught my eye. But then, I think of that dude at I met at Horizon race rocking an aluminum tub late 80's RC10 and turning fast laps. It was awesome to watch. He had mechanical trouble but it was fast.

Still loving the Kyosho.

I recently picked up a super shorty from Pro Tek RC as well and it's very short in comparison to my 4400 and 4600. I figure I need to use short battery posts so I can lower the brace, has anyone else done similar things?

Super shorty brings the car under min weight very easily, I think I'm at 1480 now. I'll weight it again later and post.

Just put the exotek frt ti axles on my stock buggy. Ised a b5 frt crush washer and worked perfect to get the stock track width with the stock spacer on the rear.

I started with 37f/32r and it didn't feel to bad. I quickly went to the more preferred piston set ups.

I have and prefer to try and keep the rear track width and rear pivot widths as separate as possible so I can tune each separately. Traxxas makes some .5mm Teflon shims that work pretty good for a more precise width adjustment. You do have to use the kit metal shims on the back side at the ball end of the axle stub so there's a little more surface area to keep the Teflon shims from slipping over the little lip the axle stub has.
