Thanks for the help guys. The caster change worked well along with less camber. I've ordered springs and will try different tyres front and rear this weekend. Wednesday nights track I believe I can go softer rears, where as Sunday's I think I'll need to try Pinks. I'll be back then asking more Q's

I recently got a new 16 ball CRC spur and 3/32" diff balls, However I think I screwed up and ordered the wrong balls.

I ordered the following:

Could someone direct me to the correct part# for this spur, the balls are too small, they just fall through.

Thanks

1/8" balls

cerms but you need 2 packs as they come in 12s

Perfect!! Thank You.

1/8th are too big for the new CRC spurs...they do indeed use a 3/32nd ball. These do not snap in like the Kimbro gears and will slide through. Also you need to make sure you use an unflanged bearing in the middle.

Does anyone have a list of brushless, 1s compatible speed controls? Looking for something easy on the budget for 17.5 racing.

Hobbywing 1s, Novak 1s, LRP (norsam) v2's. All have booster buildin for 1S. I think that's it at this moment.....

I'm trying 1/12 for the first time on a budget. First question, is the KO VFS-1 BMC still a competative system would I need a specific profile? Is it 1c ready or do I need to get a smart boost. Can you use a standard size servo in a 1/12 CRC. I know the Futaba 9650 is very common in 1/12 racing but can you run a very good standard size servo is the question.

Thank you for any help........

Nope, a standard servo will not fit in any 1/12 scale. Its best to save hour $$ and buy a good servo once vs. Buying a cheap one. No a getting a good o e later.

I dont know ne thing about the esc.

Eric is right, 1/12TH cars are designed for mini servos, and they put a lot of stress on the servo so get a good one like the 9650. Your speed control will work, but you will need a receiver pack or a booster. As for programming, check for a KO thread and see if anyone there has a clue. I'm not sure what the KO has to offer or how to use it.

SpeedPassion GT 2.1 EX. They are all I use along with their 1s motors!

Actual price is around $125.

the last 2 digits in jaco's part number is the shore rating. bigger shore is a harder rubber. there are 2 rubber families:
1) black,grey,yellow,white (orange is grey/yellow) are for carpet and wear is higher than the other set

2) purple, lilac, 2xpink, magenta, pink are (shores are 40, 38, 35, 33, 30)

2xpink, magenta, pink are your rear choices, all will have more grip than grey.

I think Dirla is incorrect.

I have this spur myself and it uses 3/32 diff balls for certain.

Straight from the liked website above

"This is an optional CRC 64 Pitch, 72 Tooth, 16 Ball Pan Car Spur Gear. This spur gear uses 16 3/32" diff balls rather than 6 to 12 1/8" balls. This is done to reduce weight and maintenance by increasing the surface contact area, so less tension is needed on the diff nut to keep the diff from slipping. "

It is ok if the balls fall through. They do not snap into the spur like the kimbroughs do. Roll the balls through some 6636 ae lube before placing them in the spur, or build it on top of the inner diff ring half assembled on the axle.

Just to be clear, you're talking about bearing #2 in the attached pic.
This is for a 12R5.1 axle, would either of these work?

The Associated bearing is .250"x.375"x.125"..so about 6.35mm x 9.5 mm x 3.175mm. The spur i'm using is: http://www.amainhobbies.com/product_...-Spur-Gear-72T

Thanks for helping the noob!!

The un-flanged bearing would fit into the spur gear #1 pos according to that pic.
#2 pos is the bearing for the inner diff hub, that will need a flange.
