You can say that again

Tamiya Japan.. still has a few spares for the TRF503 just not any front towers until the middle of the month

So the 503 is about 5mm longer than 502X both in standard form. I'd say the 3.5 toe on the 502X would reduce the wheel base by a couple of mil. However I find the 502X more stable out of corners with the extra toe.

Thanks...

I might have a slight case of OCD

[SiR_Dave]

BTW this is what 55000 yen gets you.. when you open the box

[SiR_Dave]

Also a little comparison for those of you that were wondering about the differences between the TRF511 Upgraded chassis and the TRF503 chassis

[SiR_Dave]

Little bit of Diff gear prep being done
400~600 grit sand paper to smooth out the back sides of the gears... they were very uneven and rough...

and the progress so far

So beautiful!

[Aussie Top Force]

Great pictures keep them coming!

[SiR_Dave]

OK... few more updates..
How about a few new front hex options.. 12mm and 10mm
3mm~3.5mm thickness, so using a Kyosho ZX-5 / Losi 22-4 front rim should not be an issue for 12mm front wheels.. also the offset is only 0.5mm wider

[SiR_Dave]

How about some other parts that crossover from other Tamiya cars that work with the TRF503
TRF417 Steel light weight outdrives... need two sets to make it work on one diff..




TRF201 Light weight vented slipper plates and TRF 501x Bulk head brace..


TA-06 Front 39T One way.. for you that are brave enough to use them

[SiR_Dave]

Chassis Build up is all done... Off to build the shocks next and finish up the Electronics and wiring it up

Just a quick question....why you using the front hole on the alloy hub carrier?

[SiR_Dave]

Had good luck with that location before on my TRF502x... the car reacted a little bit more to my liking with the shorter link

[pugs]

I see mate....you might change it back when you try the car

[SiR_Dave]

Cool...
I'll try both locations chassis length is a bit longer so if might be a different feeling

[pugs]

yeah try both mate, the car is sharp even with it in the normal position.....noticed you didnt add the rear roll bar...a good move, i disconnected mine in a practice run

In respect of the front oneway, is the diff locked when under power? I always ran my Egress, Top Force and Yokomo YZ-10s with the one way, but the one one bearing was not in diff, it was elsewhere in the drive system of the respective buggy. Thus the front diff acted like a diff.
