What do your outdrives look like when you replace them? Mine do not show wear 8 weeks in.

8 weeks with no wear must be stock racing?

Any car I've ever had with 10+ runs/week would have notchy outdrives after that much time and be noticeably unpredictable handling-wise until they were replaced.

How much slop do you guys have in the dogbone couplings before you replace them? My rear wheels have enough slop in them that I can rotate them a significant amount back and forth without moving the outdrive. It seems to be coming from the coupling by the looks of it. I'm guessing it's time for new dogbones?

My drive terrain is solid after a year. But I run stock on low bite

Yea the mod drivers are the ones who are really tearing up the out drives.

Mine are like that also where there's a significant amount of play. I would think the out drives and dogbones would have to be replaced at the same time or else the worn dogbones would wear out the new out drives and vice versa

Also, if anyone wants my XP 1015 servo that started to crap out on me for parts or you know how to take it all apart and find the problem, PM me and I'll give it to you, just pay for shipping to wherever.

How big is the track you're running on?

Not sure, pretty decent sized tracks, OCRC or West Coast in SoCal

Wildcat1971,

What set up are you using? I run on an out door drying loose track. It has a hard pan underneath and a loose silt on top.
I am running the following set up.

Tires - m3 hole shot fronts, green goose bumps rear & stock foam on both.

Front :
Shocks - Green spring, 2 x 1.6 flat, 30 wt, 1 tower, O arm
tie rod - 1 in (2mm washer) and A out 30 deg. caster
Rear:
Shocks - White spring, 2x 1.6 flat, 27.5 wt., 1 tower, I arm
tie rod - 1 in (2mm washer) and B out, 0 deg. hub
This Steven Hartson set up

The buggy is loose on power
Thanks for any help
God Bless

We run on a medium size track with a few decent straights and a few small jumps. I was thinking of replacing my full size packs with some shorty packs . I was told that the b4 was light and worked better with the full size packs as opposed to shortys. Anybody know what the benefit of a shorty vs a full size is other than the weight.

IMO, white is too stiff in the rear, I would go green. I really dont like the 1.6 pistons much at all. My personal favorites are the 1.4x3 pistons. If they are too pricey for you, try the 1.7's with 37.5/32.5 oils.

Naaa , just the amount of runs ....

Maybe stock wears a little less but not much less....

17.5 is nothing but a mild mod motor these days ...


All new parts make for consistent cornering & forward traction at it best .

Car handles & traction is much the same as a with full size pack.

Jumping & landings are improved ....

So do u suggest using shortys over full size packs.
