A few more observations...

Ok the car IS light. 50g less than my 104 X1! That is using the same front end, same electronics, same rear shaft/diff assembly.

Next, the new top deck makes removing the battery way easier. One must be careful, though when putting it back in as it's easy to put it back slightly skewed. Make sure really back in place before tightening the screws.

The new shocks are very smooth and easy to build. they require oil much heavier than I expected, but are fine. Since they're a through and through design, they don't require a bladder and have no rebound.

The rear pod top deck is not so bad, flex wise, but the plastic left front post supporting it is truly bad. it's extremely flexy. had to replace it with a post from my 104 X1 and a few shims. Makes it much better.

Side links look flimsy, so I would probably stock on them as I don't have much faith in them surviving a crash. I may be wrong, though (I hope).

Not much else... Simple and elegant design. I believe it should be a very good car.

I'd rather use the ESC throttle profiles or the radio's EXP on the throttle channel to smooth out the acceleration. As for the weight, I can always slap a few lead weights on the lower pod plate and get the same result if needed, but have the weight sitting lower.

But you're right, it's all personal preference.

Thanks for the info. So you didn't use the new diff? Hopefully tamiya starts supplying some parts. The roll damper and the f104w gp t bar are still near impossible to get replacements.

I wonder if the F1r side links fit on. Mind telling me the length of the links?

How do you find side to side movement with the link chassis? Smoother than the t bar design?

The steel shaft also seems to help with adding some flywheel effect as well. I tried it with foam tires on carpet and it got the rear end overly stuck to the track. I would assume it has a similar effect on rubber, and is why the X1 came with it.

Carbon is always better for acceleration, but sometimes that doesn't mean anything if you can't hook the tires up.

I would bet that the whole rear end is RM01.

I keep checking this thread to see where might be selling these online that post to Australia and sell 417x lower chassis. Fingers cross it's not much longer now as I only have a 12th running right now that we don't race locally.

The diff is the same as with F104 pro/X1/wgp...

Links are 65.5mm from center of the ball to center of the ball.

Side movement is much different. It's hard to express with words (English is not my primary language...), I'd say that even with the side spring tightened correctly, it feels different than with the high traction t-plate. roll seems much more constant, as with the t-plate, it would seem to me as if it gets stiffer as you roll more.

Pretty much is, save for the lower plate witch is different than the one for RM01.

I ran the X1 when I first got it back to back with my Exotek conversion. The link cars seem to feel smoother and easier to drive in a lot of situations.

If this car is similar to the Exotek, it will be very good.

I thought I read the diff was changed, 417 rings or something??

It is but the old one is compatible as well.

Here's a picture from the other thread that shows the change in design...

So the Diff rings are the only change? It is not adjustable without removing the rear tire like the RM01?
