Just have to throw out a dumb question here.
Just wondering what most people are running for spur and pinion gearing for stock TC. I am currently running a 96 spur and 39 pinion for an FDR of 4.18. Current temps at the hanger run 105 to 120. If I am not mistaken good temps for brushless are 140-160? If I understand correctly than I could easily gear up. My other question is this: If I want to gear for faster straight speed but slower acceleration in the infield which way would I go? Bring the two gears closer to the same size or farther apart? Just throwing some things out there. ![Laughing](https://www.rctech.net/forum/classic_images/smilies/laugh2.gif)
See ya'll wednsday.

another thing is different brand motors do run better at different gearing, if you want you would be safe to go up at least two teeth on the pinion. this 'should' give you more speed on the straight, but it 'may' also give you more bottom end for the infield. despite what some will tell you, spur/pinion combo DOES make a difference in the feel of the car. if you have the options, set your gear around 3.8 with a 96 spur, and then if possible to get a 3.8 with a 106 or 110 try that. you should feel a difference in off power corner speed, drag brake, and accelleration. all in my opinion.
btw i to am running a 96 spur in 17.5

Rdog,
Brian and Mike and a few others are more informed than me, but I do know that 80mm or so would be a good starting point. If your speedo is a Tekin and you have the version with Turbo them maybe gear more like 65 or 70mm.
I am sure this question will be answered by a few more of the Hangar's finest.

hey this is stewart. some of you know me when sir was still around. havent been doin any racin cause i been debating weather or not to drive to hanger 30. but i think im coming to my conculsions. i was the one always crashin into people till i figured out how to drive. lol
im lookin for a brushless setup. esc and motor. not sure what i want. but a good setup would be nice. i still have my ifs. i also have a 1/12 crc chassis carpet knife for sale if interested. 2 bodies. 1 set of new tires and 1 used. one built battery pack and 2 unused i think. comes with esc also. any info on how to start racin up there would greatly be appreciated. i get off work at 5. so hopfully i can make it there from renton on time.

Randy 75 to 80 rollout should be a good starting point depending on how the speedo is set up. I was at a 79 at TZII with a lot of timing advance in the ESC. Others were higher in the mid 80's but with less timing advance. I will probably drop 2 or 3 teeth to run on Weds.

ROAR cannot stop it without actually changing their rules. Once it's released to the general public there are no rules governing the ESC. Also, I would not call it a no brainer to switch. It's more like the flavor of the month. The last big national race it was the Tekin and the next one who knows.
Anyway, why am I hijacking this thread?!

if the ESC is banned, does Hanger 30 plan on following roars lead, or will it continue to pick and chose which roar rule to follow?

All this talk about rollout made me realize that I have no clue where to start....
1/12
Sphere
17.5 Duo
If I understand correctly, the lower turn the motor is, the more RPM it should be spinning...? Using that as a guide and what you guys have recommended as a starting point for 13.5, I should shoot for around 85ish? Way off?
