The PRSB401 buggy is just as good as the xray... I have maney friends that run the xray and a few that have the SB401 and they are really close...

I ran an XB4 all last season and loved it. It was reliable and seemed to work well on nearly any surface.

Plastic/composite diff gears were a bit of a concern at first, but proved robust enough to still have the original gears in it when I sold the car a month ago.

Had the SB401 now for a few weeks and I like it. It's built like a tank. Still breakable as I've proven!)

It's not as good as the XB4 in some respects - it's noisy (more later) and in saddle layout, it's heavy. Also, to me, it's not s good looking.

On the plus side, though, it's got all metal drive train, is superb to build, has top quality components including the shocks, which are lovely, and it's rare! I like rare cars!

Time will tell if it's really as good as the Xray, but let's say, it could be.

The noise issue is a pain. I have carefully shimmed both diffs to get it to run more quietly. It's lots better than it was, but still makes a bit of a racket. I can live with it though. I'm thinking it's going to get quieter as it beds in - hope so!

Center diff is standard

I appreciate an honest review. I have heard a few times on here that it is noisy and absolutely doesn't look as good although your pics look pretty sweet. My 2014 XB4 and my PRS1 have been killing it on the track here and I'll probably just keep the Xray for now. I really want to try this car but maybe I'll wait for a version revision down the road as my xray starts to age.

I'm on the fence on which wheeler to buy. Someone told me the SB401 can't have the quality CF and aluminum chassis and sell it for the price it is. He doesn't think it will hold up to the rigorous abuse in mod setup and the plastics are not as tuff as the xray or D413. The D413 was my first pick until I found out how time consuming it is to get the diff out or trying to get parts. I really like the SB401 just wish some of the top drivers are driving it and winning. Guess time will tell.

Quality of components is absolutely first class. Plastics are superb. Noisy? Yup, but much less so now than it was when I first built it. Now sounds pretty much like any other shaft drive car with metal diffs.

Ran it today at a smallish club meeting (only 12 4WD cars) on an all carpet track. Car wasn't particularly well setup for carpet, but I still stuck it in 3rd for the final. The car has potential alright.

Thanks Jimmy, I used to race 6 years ago in the nitro class 1/8 scale. After tons of research I feel picking the PRS1 v2, I made the right choice. Just having a hard time getting used to the smaller buggy on clay tracks. Lol I did race the rookie class my first time out and took 2nd, but I'm sure I will improve as I get use to the buggy. I saw the SB401 in action and feel that is one bad wheeler. My friend is just giving me second thoughts wether to buy or not, but I really don't know anything about these new wave of 1/10 scales. All I know is the SB401 looks to be a very nice buggy, I would think it is on par with the others like Xray, D413 and the ZX-6

The quality or the carbon and aluminum are just as good as any brand out there. The SB401 is just as good as any of the other cars, with the right setup and proper driving any car can win. Hell look at the 22-4 , it's a very very old design with some updates and it just won the Reedy race.

Thanks, so how much does this buggy weigh when fully setup and ready for the track? Shorty battery

Mine is 1830g in saddle. Shorty is 40g less, so 1790g.

Jimmy, what adjustments did you make to the gear diff shimming to quiet it down? Was it adjusting the internal shims and or the outside to adjust the mesh with the input gear? I've always ran ball diffs so this car has a bit of a learning curve for me due to the diffs.

Are there any aftermarket or other brand bodies that fit this chassis well?

I adjusted the shims on the diff itself. Just remove the gearbox with the center driveshaft attached and the differential still in and the cover removed and just spin the shaft and listen. Mine was actually a little too loose, so I put a couple of shims in the appropriate place and gave it a spin. You can hear the difference. Just trial and error!

Shimming the pinion might be worth a try too.

Jimmy.

Not sure, but I would say any shell for the Associated B44 should be close, and even the Xray XB4 shell?
