Thanks!
the 9650 is not the smallest, lightest, or fastest servo around. but they are smooth, accurate, affordable, and ultra reliable. I generally use 9650's in all of my pancars and have not been tempted to use anything else. In a Rebel, they bolt right down to the holes provided and it is handy that no servo mounts are needed because you can just use the flat-mounting tabs that are a handy feature of the futaba servos.

Currently running Black/yellow combo but I know there are better combos. I have been looking at the BSR Blue/double Blue and green combos and Ulti options. Will be running 17.5.
Any help is greatly appreciated because my head hurts reading for the last 3 hours on all these newer tire compounds.
You already know what tires are working. Just stick with what you know.

I'm in the process of rebuilding my car post season. Is there anyone using a Futaba BLS651 that's mounted to the chassis without gluing it? What are you using?

My back-up car has a Futaba 9650 in it, attached to the chassis using the mounting brackets on the case. I wouldn't be surprised if I performed the same installation in my primary car as well.

You mean those things I cut off to fit in my other 12th scale car...DOH!

Default Spurs

I've been reading over this thread for awhile now. First just wanted to say it contains a large amount of information. So thanks for that.

Backlog, I got a Rebel and drove it and 1/12 scale for the first time. It rocked. Loved it. I'll be adding 17.5 1/12 to the classes I'm running.

The only question that I can't quite find in this thread is about spurs, specifically how they relate to diff balls.

My used kit came with a 73T spur. Works fine, however I'm sure I'll need to replace it. As such I ordered a few things from Arrowmax and one was a 74T spur that I thought I might give it a try. Wrong, the relief for the diff rings is 24.7mm in diameter. Thickness around 5mm outside of that near the teeth.
Diff balls won't touch the plate and the diameter of the diff holes will not allow such a big diff ball to increase the thickness. I assume if I would like to give this spur a try I"ll need smaller diff rings?

Looks like if I ordered a larger spur the Rebel rings would of fit. Who knows what tooth I would of needed though.

Is there some sort of guide of which spurs fit the Rebel or other cars? Guy that sold the car threw in another spur. Little known to me it was a CRC. From the look I got when I showed a fellow racer that wasn't going to work. I guess I'm lucky that it was thrown in with the kit..

I also noticed some talk about moving the motor forward by using the a large spur. Is that what the cool kids are doing now days?

Thanks in advance.

Several ways to go about resolving this issue... No "special" spurs are required, just compatible diff balls, diff rings, and spurs. Easiest way to address fitting spurs to the car would be to use PRS, RW, or Core R/C spur gears (they are flat, and roughly 3mm in thichkness), and using 1/8 inch diff balls. TOP diff rings should work without any problem.

I bought me the option motormount-kit to use smaller spurs and coming on a rollout of around 63 mm. I also can use pinion like from 33 to over 40.
I suggest to check out what rollout you need with your motor.
Actually I use 78 spur, 36 pinion with around 43 mm diameter of wheel in the back (front 41.5). Driving 10.5 motor 1S lipo.
By the way, I put the balldiff together only with GearLube, no grease!
Works fine over 100 minutes without taking appart again. Very smooth and no adjusting's needed (checking it after every 8 minute run).

D4 17.5. 42mm diameter F/R. 73T spur. Rollout 100mm. Which puts the pinion at 55T.

Can someone post a link to the washers used on the upper hinge pin?

Many racers use these:

T.O.P. Racing Products #PA-100204 Shim Set 2 x 4mm .1, .2, .3mm (10 ea)

I've recently started using these from McMaster-Carr:

#95610A510 Nylon Flat Washer, M2 Screw Size, 2.2mm ID, 5.0mm OD
You have to cut a flat spot on one side as the OD is too large, but they are easier to use than stacking up all those stainless shims.
