Can't believe 3racing still haven't released a narrow version of their car with that awesome front end. Looking at it, it doesn't seem too hard to do and it would move the pick-up points under the body. What are they waiting for ?

Hey guys, just ordered one of these and waiting for it to turn up. Any tips on a starting point for FDR? I'll be running 21.5 on a fairly small indoor carpet track, main straight is only 20m long.

Also, what bodies can you run on these with the stock front end? Looking for something a little more modern even if I have to cut it to fit the shocks.

Edit: the suspension bit might not even matter, not even sure if I can race with independent front suspension on my track yet.

Any tips on a starting point for FDR? I'm running on asphalt 30 foot straight.

So What FDR should you start with?

Does any one know of a carbon rear axle that will fit this? I have bent two of the steel axles and while I should probably just stop hitting stuff I would like something less prone to bending.

I know the F104 axle wont fit since the shaft is 6mm and the F113 is 1/4" or 6.35mm. Does anyone know what might fit? 3 racing don't seem to make a carbon option.

I reckon a Yokomo yrf001 axle would be extremely close, you would need to use the yokomo diff rings on the 1 side. Ill see if someone has a 113 axle out of a car so I can compare the lengths at Castle Hill on Friday. (Rob Wright I am looking at you)

Sorry and yes the shaft is 1/4 on the Yokomo

I do have one of the F113 shafts out of the car, it is 125.35mm long including the screw thread, screw thread section is 8.20mm if that helps.

What is the length to the diff plate ?

Does this help? The pink section is 6.32mm, screw thread 8.20mm. That's pretty much everything I can measure!

Thanks!

yokomo axle is 117.10 long (not including screw end), 91.5 mm to the diff plate on the left side and 20mm on the right side. Its very close...

Thanks for that, I might have to try this mod.

For anyone who is interested, the Yokomo YRF rear shaft will fit straight onto the F113. All you need is the Yokomo shaft and the diff ring for one side, the rest of the 3Racing parts will fit straight on.

That's great to know, glad I could help... I wonder if the yokomo steel axle is stronger then the 3 racing one ?
