Looking for a spur gear and pinion manufacter called D/M or something similar (DM?). It's printed on their spur gear. Anybody know of their web site?

sands, I think that's DuMar spurs? I think Trinity used to distubute/repackage them. I don't know if they are still around, or if uncle Ernie bought them up.

Hey Paul , how are you doing ?
good to see you doing well, I was thinking of running up there this weekend ( southshore) it is only a 4 hr drive.
Paul, you guys run mod out there?

thanks for the oil info, I was thinking what you said Cypress, but wasn't sure, What type of sliders are you guys using, I have the large bore ones on , with Losi light hydra drive, was wondering if using small bore ones with med. fluid would be any different,

What I'm really looking for is a spur larger than 128 / 64 pitch. Anybody hear of one?

Casey,

They only have a 19t class or mod for TC and stock and mod 1/12. I will run what everyone else is. More than likley 1/12 stock and 19t tc. I would be up for some mod TC though. I have been running some mod TC so far this year at our track.

I'm running the plastic (small bore) tubes with Medium. I noticed that the small bore tubes seem to have greater dampening than the large bore ones. I usually use Med. or light Hydra fluid.

Does anyone know what companies and where I can get machined 64 pitch spur gears? Even more effecient and even quieter..... I think ;) :) .

RW (which is basically Schumacher) sells the best spur gears out there. Although I heard that Yokomo also sells white spur gears that look similar to the RW ones, however I do not know if they are machined delrin like the RW's.

Stormperson, can you use large diff rings together with RV spurs?

Wow, that's freak'n huge! Hope you're running big tires if it's on a pan car...

I think it may actually be for a TC. I don't think 12thscale tires come out of the package as big as a 128 spur.

i just got new tires for a new season of 1/12 racing and im having problems figuring out gearing cuz i havent touched the car for like half a year, the track im running on is a highspeed track, 2 sweepers and 2 doglegs. track size is 80x40 ft. i want my tires to last the whole season so what kinda gearing should i start out with?

thanks

This is what I use for rollout. You'll need a set of calipers to get tire diameter.

I was thinking 1/10 pan car, as I used to run a 125 on my old cars (back when people atcually ran these on road courses!). That was cutting it clse when the tires got worn out.

Brolzy,
 

I run 1/10 pan car road course in the TC class. I do OK for a crummy driver. I seem to get better each race. I am sure I could beat the Stock TCs with my RC10L3. When I do, they will contest the weight. That was this summer in parking lot racing. It is an orginized track with transponders etc. This winter, I race indoors, a little more professional. While running my Carpet Knife, I asked if I could run the RC10L3 in the TC class. They said yes. I know after each race in tech, they put your car on the scales and check for ride height. SO I bought some stick on wheel weights. I am going to try it.

Sands,

I don't think a 128 spur will work with 1/12 tires. My 100 hangs below the chasis now with good almost new tires. I run 28/98 or 100.

First race of the year was last Friday night. I did not come in last. First time ever. I did 37 laps, the winners did 45. I love my 1/12!!
