lets put it this way, a ball diff is proven to work in a 1/10 scale car, and a gear diff is proven to work in a 1/8 car. why dont we keep them in their places since that was what they were designed for. you can put a ball diff in a 1/8 scale car, but is it pratical? all im sayin is "if it aint broke, dont fix it".

Hi fellas,

What effect does lengthening and raising the camber do ?? I realize that longer camber has a bigger effect than raising it by washers...true?

Cheers.

HanIce, raising the inner ballstud lowers the roll center. Lengthening the camber link also lowers it, but not at the same points. What changes more with each adjustment is roll center migration and polar moment, much more with camber link length though. Basically a longer link will make the car feel stiffer on that end and help the chassis recover better with the same shock settings.
A shorter link is better for rougher, loose tracks that don't have many switchbacks style turns, since it allows the roll center and polar moment to change much more, it can sometimes make handling less predictable on high traction surfaces though.

Everything is a trade off and most of the time trial and error are your best friend. This is where time and effort pay off in track time and testing. Knowing what each change "Feels like" is the most important thing when it comes time to hit the track.

Try one at a time and take the time to make notes of conditions and the result each time. Nobody can remember every change and every condition, so this is the best way to accumulate knowledge over time.


There are also some very good suspension books you can read, just google suspension tuning and you can really learn way too much stuff! lol

Hope this helps,

Since i'm doing long posts, i'll chime in on the ball diff vs. gear diff debate...

The ball diff is lighter and more compact and is designed for short races, like 5-8 minutes or so. It requires more maintenance and only allows a "tiny" adjustment range.
Great for electric cars and small trucks, where wieght is more of an issue then durability.

The gear diff is far more durable, heavier and bulkier, it requires less maintenance and can be tuned almost infinitly.
Great for 1/8th scales, large trucks and longer races where durability is more important then wieght or size.

That said, I would think in a gas truck, even 1/10th scale, or a large electric truck, like an SC10 a gear diff could be a very viable option.

But a ball diff in an 1/8th scale would be done in 5 minutes. Even one made larger and more durable could not handle the wheel speed from overpowered cars with relatively small tires....

Not that i think a ball diff in an 1/8th scale is a good idea or not, but with this attitude we would not be where we are today. Sometimes you have to try crazy stuff to see what works and what doesnt. Big manufacturers (AE, losi, etc) are constantly trying stuff to see what works.

A couple of guys asked me to post how i did the QR in the front so here it is. Cameron Kellog has one that is much cleaner and my V2 will be better as well but it works. By the way i cant say i came up with it. Scott54 told me how to do it.
Anyway just need to narrow up a set of XXXcr spindles and cut the end off of a rear axle. I have it back spaced so the pin hole lines up but my next one the spindle wont be narrowed so much and i plan to just use a set screw and shave a lot of the QR hub off.

Default RC10 B5?

Anybody hear any rumors about a release of the B5 in the near future? We are about to start our winter indoor season here in CO and was wondering if I should hold out for a B5?

A B5 will come out when the B4 starts to lose market share, doesn't seem like that's happening for a while.

Nice diff Cherry haha that looks like it was made in a shed down in kentucky

Kcar takeover? blah only one here and the thing barely can finish a heat, Kyosho bought a driver and will win a few races here and there.... but the reality is the car is fragile and not economical to club race for the average Joe, parts are scarse and spendy compared to the good old stand by's

So if I want to try the gear diff in my B4 do I need an SC10 tranny case?
