- - what about a 4wd baja? calling all baja guys! (https://www.rc-monster.com/forum/showthread.php?t=28905)

Making a 1/8 scale wider while stretching it is a must. On my stetted erevo (5b length) rpm 1/2 offset wheels weren't quite enough. Another 1/2" per side with extended hexes like brains wouldve been perfect. For my spare parts maxx build I plan on welding extensions to the pillow balls and tie rods instead of buying extended hexes though.

How would you figure even in the least that the 5b would be a bad 4X4? First off it is a rail style buggy, which in the world of a 1:1 are in a lot of cases 4X4. The 5b is in my eyes the best looking 1/5th scale R/C buggy being made, and with the way it is built can take a lot of punishment. So why would anyone want to go for an inferior design as an alternative. Converting any vehicle from 2wd to 4wd creates a less efficiant power curve, but the trade offs in basic handling are usually well worth the effort. If you put a 5b 2wd up against a 5b 4wd with the exact same powerplant, which one do you think will prevail? I would take the 4X4 any day.

The "rail design" is meaningless. All the gear was planned to be mounted in the center of the buggy, the transmission is longitudinal, and the suspension geometry is based on 2wd.

To me it's like "I like the B4, so I'm going to make it 4wd because it'd be awesome" when it's the absolute WRONG vehicle for it.

I think that with 1/8 components a 1/5 size vehicle can be made that stays well under 20lbs. A 1717 or 1527 motor on 8s lipo (40c packs, 4000mah or so to keep the weight down) and motor brakes with 4wd would be fine.

I may weld up some tubular arms to widen the lst setup. Just need to find a suitable cv axle that I can buse it off. Would use al c hubs and knuckles on the front and al carriers on the rear. Lst shocks seem fine. Or use the baja ones.

As I was building mine, I thought it would weigh in at 17-18 lbs. But with Baja wheels and tires and 8s 5000mah batteries, it runs at 18.9 lbs now. Under 20 lbs, yes, but it would be difficult to get it a lot lighter.

Wheels and tires are one of the main things that add alot of weight to a vehicle. I do agree that they look great, but I would likely just run 40 series on the back and truggy on the front. You can drop a pound or more just by swapping wheels/tires.

I would also run lighter batts, and just have 2 sets if I wanted longer runtime. With the 40c lipos I am sure that 4000mah or slightly less will do.

The HCR kit for the 1.5 maxx was my inspiration and the Kershaw kit is tempting, but I won't buy it. The build is the fun for me, I want to build as much as possible with this one and save some cash too.

My Erevo ended up weighing in at 15.5lbs, baja 5t body, brake line rollcage, mmm2200 combo, 5s 6000 25c, LST (lighter 2nd gen design) tires on RPM stablemaxx. And that was with stock, not aluminum tierods, pushrods, etc. Plus the chassis was heavier than it needed to be because of my lack of certain tools and the bolted together design I had to use. Probably could've gotten it under 15lbs though, the 5t body weighed about a pound.
