Are you positive you have the shorter 42mm front and 57mm Xray springs? I'm not positive they are stock on the 2019 model or not. However I added them to my 2018 and I easily get 14mm or lower if I wanted. Before these springs yes the factory guys cut the springs to lower the car, but I don't think that is required anymore.

hello all.
Curious if I would some answers here.
I'm racing on some local astro tracks, occasional club-races.
I always prefered 4wd because I'm not a strong pilot and 4wd is easier to drive ... or aybe because I just like the driving style of a 4wd.
But as 4wd has much less drivers over here, I tried converting my XB4 to a 2wd and had some fun with it.... So i might try a bit of 2wd after all.
The choice would be easy: on astro so carpet-edition ... but as the weather regulary enlightens us with rain ... should i choose for the dirt-edition .. which if i am correct will be better on a slippery wet astro track?
OR? is the Carpet-edition also suitable for a wet astro track with some setup-modifications?

I am looking at doing some refreshing to my 18c car. The transmission is fairly noise, at the track one guy said he put the Yokomo top shaft in and it quieted things down. Is anyone else doing this?
Is this the one? https://www.amainhobbies.com/yokomo-...-303ta/p417693
Also, for replacing the pins on the dogbones, what are people using? How long are they, I have heard they are 2.5mm. McMaster Carr has them in 4140, is that the material of choice?

TIP: I use Teflon dry bike chain grease on my transmission gears and it helps quieten them down.

Are you running the stock Xray top shaft now? Have you taken apart the transmission and inspected the idler gear? What is common is the idler gear getting worn and causing noise. First I've heard of using the Yokomo top shaft, but it looks identical and I can't see it being any different than Xray. Xray parts, and specifically gears, are VERY high quality.

Curious to hear, however only thing I know is Hudy makes a very expensive tool for replacing the pins. To the point where I would just buy completely new dog bones instead of messing with the pins.

I just talked to a Team guy, and he said the 18 cars are 3mm x 10mm, but the 19 cars are 2.5mm.

The carpet setups on petitrc show guys using the XB4 rear arms? Is this from the XB2 dirt conversion kit(#320900)? What is the advantage of running the XB4 arms instead of the XB2?

The xb2 2018 uses 2.5mm pins. Its on their website: "To improve the drivetrain efficiency, the all-new CVD drive shafts feature new 2.5mm drive pins". Some people use a bike chain breaker to replace them (didn't work for me), I use a bench vise like this: https://youtu.be/uTE6GCa-ipU
