I can understand why people would want smaller spurs just so they wouldn't have to use giant pinions, but I don't see why the current 96t would stop anyone from being able to make as low a gearing as they would ever need.
I'm running 17.5BL rubber right now, and that requires a final drive of around 4.00 and a rollout in the area of 48-50mm just to be in the conservative range. So with the 96t spur, that means something in the range of 42t-44t pinion.
Yeah, its annoying to have to run those large pinions, but even with something as large as those, the wonderfully designed Mi3 motor mount still has plenty of room for larger ones, and even lower final ratios.
I just can't see a ratio that someone would need to hit that they wouldn't be able to get to with the 96t spur and the Mi3's motor mount.
With that said....wheres our 90t-92t-94t spurs at???

Well, first, you would have to be able to actually GET a Schumacher 96t spur. 
Then, I think it would be something most people would be interested in to avoid buying pinions 40-50t for no real reason. Larger pinions, more rotating mass, belt/pinion interference, and just the general pain of having to use uncommon pinions and spurs would all be nice reasons to have a different internal pulley ratio. I'm sure there are more reasons that I'm not thinking of, but those mentioned are worth the trouble in my opinion.

looks like McGoo (bald guy) is adjusting Marker (hairy guy)

I haven't used anything below 38 since I started running brushless, and I prefer to gear in the conservative range. And thats with me using a tiny 90t spur on my TA05 back in the day. I mean seriously, have you guys seen some of the pinions that the JRX-S Type R and Cyclone guys have to run!!! Those things are nearly spur gears!
Heck, I considered us Mi3 users lucky to only have to be in the low to mid 40t range.

I didnt see the need for such a small spur gear either until I put a 10.5 motor in my car and realized it was crammed right against the ESC.
It isnt that the 96 spurs are hard to come by, its that they arent yet out. They should become available early Feb and should be easy to get at that point.

~ proper preparation prevents piss poor performance ~
i propose that jaybee (sweet jerome, as he likes to be called) goes over every team driver's car before each big event. new mounting, new wiring, and whatever balancing he deems necessary. it should be mandatory that all team cars look like (or near) those that jaybee has shown us. simply awesome, sir.
then, the cars will be shipped to randy caster (aka - randall 'the vandal' caster) , where he will properly shim and align them.
meanwhile, mcgoo's painting up shells for each of us (since jaybee's already busy stripping wires) ...
finally, the finished package will meet their owners at the race track, ready for battle.
so, what do think about this adam? can you mandate this? we'd be alot better off, let me tell you. instant demotion/suspension for anyone caught with a rat's nest or air in their shocks? what do you think?

Maybe thye went through thier stock faster than expected and will be getting more, in early Feb???

Heres what i came up with for layout on wiring.

How do you like these #'s Randy
Hey guys, do you fret over balancing your cars? I do
I use the four scale method and balancing the car yesterday, here's the numbers-
Left side
LF- 350g/ LR- 333g = 683grams
Right side
RF- 341g/ RR- 345g = 686grams
Cross weights (L-R)
LF- 350g/ RR- 345g = 695grams
Cross weights (R-L)
RF- 341g/ LR- 333g =674grams
Front to Rear %'s
LF (350g) + RF (341g) = 691grams - 50.5%
LR (333g) + RR (345g) = 678grams - 49.5%
Overall, I'm happy how it turned out but I'm not satisfied with the Cross weights. I got some more work to do.
Any suggestions?
