I used some slip-joint pliers for mine... They let you push on the ballstud a little more evenly than using a pair of pliers that have a statick hinge (like needlenose pliers) plus they have a large flat surface to make things easy, and the longer handles give you more leverage.

Along with what's in the post above this one, the manual shows which side the balls need to be installed from. They definitely install from one side and not the other.

You can go bigger by using smaller spurs for the RC10GT2.

You can get them in 52, 54, and 56t flavors if ThunderbirdJunkie recalls correctly.

He will consult the packages his spurs came in and correct this post accordingly.

I raced at west coast today. I used Cavs set up & the truck was a night & day difference with the front & rear sway bars! I qualified 3rd overall but blew it in the main & finished 5th. I'm looking forward to putting more & more battery packs through the truck!

Running 11/62. Need to get a 12 tooth pinion for it.

Hey TBJ I was wondering, I am running a mmp w/ tekin 5.5 sc4x motor, I only have a 16t pinion for now, what size spur should I go with? Or is 16t just to much? Thanks

Honestly dunno...15 or 16 should be alright. Aren't most guys running 4.5s running 13s and 14s?

BTW...did you see the top secret stuff over at NC?

Well I just thought 16t was to much and would cause overheating, I ran it with the 16t/62p last week at the indoor track and after about 4-5 laps it was tempted around 160 I believe, so I'm thinking maybe if I drop the spur down to say a 56 I should be fine...... Oh and I'll check out NC after this

I'm running 12/62 with a 4.5 at west coast...I would think a 13 or 14 would be good for a 5.5 if your running at ocrc or wcrc.

Nah I run at Coyote Hobbies in Victorville....... I'm going to try dropping down to a smaller spur to see what happens. I did buy a 12t pinion but it hasn't came in yet........

It depends on the motor. If it's a short, small track (like the one you linked a video to on NC) a 15 is probably too big.

If you're not looking to gear higher (IE bigger pinion) then the bigger spur gears aren't in your cards...but they do allow more finite gear ratio adjustment.

I am very satisfied with mine. I bought it Tuesday, had it completely assembled on Thursday. I ran two packs through it Friday to shake it loose then went to the local club race Saturday. Qualified 3rd with fastest lap and finished 4th, good for me! With a little more consistency I am in the top 3! Very happy, our track is a big 1/8 style track but the 4x4s run hard and fast on it. Props to the Castle 1410 and MMP, hung in there nicely with all the big 550 cans.

Going to a smaller spur gear is like going to a bigger pinion...it will make the truck faster. I don't know how big coyote is, just watch your temps.

Has anyone had any experience running this truck with the new Tekin, LRP or Novak 4.5T 550 motors that have been developed for this class..?

Just wanting to hear your feedback before i make a decision on which one to go with...

12t with my LRP 550L 4.5turn.
I am getting around 145 here in Vegas. (BTW, its 107 here now) 108 on the Rx8 speedo.
