To anyone who is interested, PitBox Hobbies is having a clearance sale on their 8-32 Low Profile Aluminum Wheel Nuts, various colors. I believe Associated off-road cars are about the only ones left who use 8-32, so there you go.

what diff do u run gear or ball? indoors med to high bite track.

Way more then just the chassis.... You also get the +8 body and the ballast weight and you get the factory team 0* hubs.... that's like over $50 bucks in things that are better then the standard kit, that's not even counting the cost of the chassis.

ball

thanks

Same kind of track. Ball. I tried the gear diff with various oil. Liked the ball better.

Cheap shipping on those clearance wheel nuts too. That's rare.

It could be any number of things causing your concern and it can very hard to diagnose over the forum. I'd look for someone at your track wearing an AE shirt running a B4 and ask them if they could give you a hand. They will be able to look over your car, watch you drive it and give you some advice from there
I'm curious, are you running a ball diff or a gear diff in your car?

that was my first question..you could be diffing out

So there seems to be alot talk about Ball vs Gear lately and I wanted to post this from AE's r/c handbook just for knowledge of fellow peeps.

Differential
Your buggy or truck gearbox (transmission) is fitted with a differential. The purpose of the differential is to let the wheels turn at slightly different speeds. This is necessary to help the car turn corners. When you car turns a corner, the outside wheel has to travel further than the inside
wheel, thus it needs to turn slightly faster to keep up. Differentials (or diffs) in model cars are typical of two kinds. Entry-level cars (from companies such as Tamiya or Kyosho) often use ‘gear diffs’ while more competition oriented manufacturers use ‘ball diffs’. Both work in the same way, and largely achieve the same thing.

Ball diffs, however, are slightly adjustable. By slightly increasing or decreasing the tension on the diff screw (see your instruction manual for details on how) you can make the diff ‘looser’ or ‘tighter.’ A tighter diff is one that is hard to turn. Tighter diffs help your car to put down power coming out of
corners and in a straight line, while looser diffs help your car to turn corners better. If you loosen the diff too far, it will allow the diff to slip, which is a bad thing. Diff slip damages the components of the diff and is inconsistent. Your instruction manual will describe how to tell if your diff is slipping or
not. I never recommend running any diff slip, because that’s what a slipper clutch is for.

A Google search gave no clear help..

What's the difference between setting the throttle (soft, normal, hard, max) on my ESC vs. setting the trim on the gun? Specifically, if I handicap the motor using one or the other, am I causing problems (heat, harder on the motor, etc.) using one method over the other, or does it not matter?

I'm sure someone with years of experience can shed some light.

I want to use the kyosho grooven o-ring in my b4.1 shocks and I was wonderig what do i have to do to make them work? thank you

Just buy and install. This was talked about a few dozen pages back. Kind of an expensive upgrade. Other people were getting McMaster orings at 100 counts for the price of 8 kyosho grooved rings. I personally use the stock ones without issues.

Any B4 owners know if the SC10 chassis is the same as the +8mm chassis for the B4? Has anyone tried a SC10 chassis on their B4?

That's one long buggy. No, not even close to the same. The SC10's wheelbase is about 13" while the B4.1+8 wheelbase is about 11.
