Hi, I bought used TRF416 roller and am now getting parts to race it in Stock-class. Our stock-class uses 17.5t brushless motors and other racers has recommended me to use overall ratio of 4 to 4.5. So Now I'm after right spur/pinion combination. I've been thinkin of gettin 70t spur and few pinions in range from 32 to 38.

Now I just need to be confirmed, can I use 70t spur in this chassis or not?
And is this right kind of spur?

It doesn`t matter what spur you use... 68,70 or 72t if you have enough pinjons up to 35

I have VTR Tamiya with 17.5t and i use 72 spur and 32 pinjon so ratio is 4.50 then

Have fun

Default trf416we rear toe in problem

hi all,

just bought used trf416we, somehow rear toe in degree left & right is not the same (Left: 3.5' Right: 3')

no sign of wear off on hingpin/arm/uni shaft, everything on rear suspension firmly attached

should the left & right toe-in had different value what would be the effect on the car ? which parts to adjust to make them equal

TIA

TIA

Also be sure that the wheels your using to check toe are true. If your using your plastic wheels, they are almost never perfectly round even when new. A half a degree of warp would more than typical. I see that on my Camber gauge all the time.

If your using setup wheels to measure (machined alloy), then the next thing to check would be the uprights. That's the plastic parts that hold the wheel bearings and axles. If one get's bent, then the toe will pointing in the wrong direction...

I have just aquired a trf416, It looks really nice. Iam getting it ready for racing stock class. What spares are the most used? I want to make sure Ive got enough of the parts that commonly would need replacement. Any input is appreciated. Thanks.

first of all ditch those aluminum steering turnbuckles and the aluminum
ball studs in the steering rack with Titanium and steel parts. Then swap out the front CVD bones to steel 46mm and put the stock aluminum peices in
your spares box.

Now you can load up on spares, get:
46mm hinge pins
C-hubs
Arms
Steering Knuckles
Ball studs
Spool cups (if running spool)

thx for your detail reply, i'm using titan setup tools to measure it
just check on both left & right plastic uprights, they are in good condition but the previous owner put different shim on each side

on left uprights Front 0.2+0.3, Rear 0.5 (non tamiya spacer)
on right uprights Front 0.55, Rear 0.55 (tamiya kit spacer thickness is not exactly 0.5mm as stated on the manual according to my digital caliper it's 0.55 )

will this affect rear toe in measurement ?

TIA

There are always tolerances to consider. If you loosen the suspension blocks you can shift the blocks slightly - eg rear block to the right, front block to the left, or both - to get this corrected.

Check that your hinge pins aren't bent, and that your toe blocks are straight. That'll be for me the first things to check on a 2nd hand car. Incidentally I have just picked a 2nd hand 416 and of course, 3 out of the 4 blocks were bent. It doesn't matter since they're not the ones I am using (put the short arms directly on it and C-C, XA-E).
