Seems to be the way with TRF kits, Tamiya tool up and smash out one or two runs and that's it. Then the update comes in the case of the popular kits.



Did your kit come with extra/spare parts? Spings, sways, plastics?

It did come with the bonus parts.
Pic shows all three spacers installed. I have about couple tenths of a mm to spare.
I first put the suspension blocks together loosely. Then I press back on both arms (towards the center of car) and tighten the inner blocks. I then do the same thing for the outer block but applying outward pressure to the arms. That's how I did it. Maybe I just got lucky...

Spare parts means it is unlikely to be from a different batch to the rest of us. Dunno.

But if you can fit all the spacers/shims per kit, without shaving/sanding/trimming the arms, and they still move freely - then that's excellent :)

Are associated particularly bad? I've never owned/seen one up close enough.

@cplus

I do not know it differently from Tamiya kits, never had problems with freely moving arms.

You could also 0.7mm shims take instead of 1mm shim to get freely arms.

Anybody know exactly how long the shocks are supposed to be for the 418. There is nowhere that says the information for suggested total length. I have all four of mine at 61.50. Seems ok. Just making sure

JimmyMac 07-24-2014 07:39 PM

61.5mm is standard for Tamiya shocks. 57.75mm for short shocks.

Just bought a TRF418 after being out of the hobby for 5 years. My local track requires a final ratio of 3.15 (Using a 17.5t brushless and Fleta euro blink esc)

Is it possible to run a spur an pinion to give this in 64 or 48dp? If so any ideas what I will need to get. Just started building it and worried about ordering something that will not fit.

Any help greatly appreciated.

NB: My bad - in my original post I used the 417's internal ratio of 1.947. The 418 has an internal ratio of 1.85. Correct values below. Sorry.

You can use any gear ratio calculator, from gearchart.com to a spreadsheet, to help work out what you need. In 48P, a 63 spur and 37 pinion will get you very close.

I'm guessing it's quite a large, flowing track?

The TRF418 has an internal ratio of 1.85


So you can just look for a combo to fit that

Zen racing has a large amount of the Panaracer spurs that fit. I would get somehing like an 88t (64dp) and a 52t pinion (64dp)

A 92 spur and 54 pinion will land you right at 3.15.

Cheers so no probe fitting such a big pinion under the deck?

Not that I can envisage, I have used a 50t the pinion is in the middle and pops out between the two prongs of the upper deck.

Where are you racing?

Yes, I'm running 96/54 with no problems and I can go a little bigger pinion if needed.
