Hi guys, I've just bought a Corally SP12G3 today, however, I know nuts about 1/12. Do give me some details so that I can kick start on this interesting scale...
Eg: Type of motors I should use, ESC, Pinion ratio, tires(I need them to run on carpet)....
Thanx!


For electronis ...smaller the better,
ESC: LRP Quantum Compitition or Novak GT7
Tires for Ozite carpet. Pink fronts, Grey rears.
TQ orange for traction compound.
gear ratio..depends on motor.
I run stock with 100/26 combo with a GM3.

Fish..Welcome to 1/12th, the fastest electrics available...

It depends on what gear you have already,if you have plenty of good 6-cells-try stock-theres not a lot of diffrence in speed and your garanteed to make the run time (8mins)-just gear up has much has you can-(66mm/rev)--if your able to get new 4-cells modified then go for that,has its slightly better at corners,being a bit lighter etc gear between say 33mm/rev to 38mm/rev,i use (64dp)spurs 96 to 104,pinions 19 to 25 (4 cell mod),i generally use 36mm/rev for a 12double,on carpet with 52mm tyres,the most commen used corally tyres for carpet is Gold rears-silver fronts or gold fronts but if you want more life out of your tyres try silver rears,also smaller & lighter the electrics the better..doese the G3 use tweak screws.?..oh,and use tyre addertives,sauce the rears and on the insides on the fronts,up to about 90% of the tyre, depending on how much grip you want..hope this helps
& !GOOD LUCK!:nod:

Wow, the smack is getting deep in here

Did you SUCK that bad too?:eek:

robk 10-17-2002 06:13 PM

Looking at my watch and I'm still 2 places ahead of you.

darnould: Thanks for posting the info tip on the settings. Still reading the past pages trying to catch up. I understand the running different or what you want. My TC is an X-Ray, everyone else runs a TC3.

I just got my 12L, got it used and it is a mess :( shims missing spacers missing, diff bad, bearings shot..... Just ordered another $30 in parts. Saw the post on using the .075 flex deck and got one last night at the LHS.
I have a question on spur's. What do you guys run for size? I will start in stock class, two of us trying to get things started for 1/12? Manual says the spur is 75 tooth 48, but it is 64 pitch and 88 tooth. LHS has 96 up in spurs. Also, what size should I run the tires?

newracer 10-18-2002 07:54 AM

I have been running a 96 spur, when the tires get really small it is almost as big as the tires.

fIShCaKe 10-18-2002 07:56 AM

Hey, thanks dudes.. Hey Stevie, insteresting explaination and cool set up ya have man! But I am having problems understanding what is rev and mm? Is there any other kind of simpler introduction available? hehehe... :p
I'm afraid my G3 does not come with a tweak screw, and by the way, what's the rear set up like eh? Stiff or soft rear? How's the dampening system gonna work? :confused: :spidey:

Avink1 10-18-2002 10:15 AM

fishcake, rev is one revolution of the tire. mm is milimeter. What stevie is telling you is the rollout that he uses for different motors. To figure out rollout take the diameter of the tire, in milimeters, multiply that by pi (3.1415...), then multiply that number by the pinion gear, and finally divide the answer by the spur gear. Example 52mm x pi x 26 / 100 = 42.47mm/rev.

darnold 10-18-2002 09:45 PM

RC Nitro- yeah running what you like instead of what everyone else does can be lonely sometimes but it's still the best way...have to be true to yourself.

Keep up the good work and hopefully all of the previous post you are reading from everyone is really helping you out.

Try running a 96 spur as suggested but i personally run 104 because i do mod. Tires size for the rear i start at 1.94 and go down to 1.84" which means that i must increase my pinion by a tooth once at 1.89" and again at 1.84" to keep the same rollout. i also have to adjust rear axle cams to keep the same rake from front to rear so i start off with number 1's and around 1.89" i go to number 4's. Generally the larger the tire the more grip it produces so you can use this as a tuning aid at big carpet races where the black groove gets laid down.

Kev- what time are we meeting at Venture on Sunday morning? Robk and i will be driving up there to meet you and ride with you from there seperately.

darnold 10-18-2002 09:48 PM

Kev- that didn't come out right. duhooo
what i was trying to say is that Robk and i will be driving seperately up to Venture to ride with you from there.

Arh-hah... Finally got it! Thanx Avink1! By the way, is RC12L3 a good choice of 1/12? Any comments about it eh?

RC Nitro 10-19-2002 06:44 AM

newracer: Thanks! I will install the 96 spur I just bought.

darnould: I will give you all a laugh. The forum is ~ 53 pages yesterday am. I hit printable setup and list all 1656 posts. Then I hit print.... I ran my lazer at work out of paper twice :rolleyes: I was in a meeting in my office at the time. My contractor started laughing the 2nd time...... I could not see the printer from where I was paper was starting to fall on the floor. 356 pages to print 53 forum pages. Guess I have a bit of reading to do :blush:

Thanks for the tire info, I will convert this to mm as that is what I am use to, started usnig rollout in 1/8 scale. Already made me a rollout chart for 88, 92, & 96 spurs Glad I order those adjusters! They did not come with what I got. On the rake, you lost me. :confused: My car is in pieces right now, I want to start from scratch as this car was abused, so I cannot look. On rake do you mean ride height? ie 3mm front 3.5 mm rear? 2nd question front tire size? My new ones are comming, order went the wrong place
Thanks for the great info. I am sharing this with my bud and cheif competiton, want to get the class running.

If I want to start with a new car, would you recomend the CRC or the switchblade?? We plan on running stock 4 cell. The pic I saw of the switch blade looks sweet.

fishcake, the RC12L3 is a very good choice for a 1/12 scale car. It is very easy to adjust and well designed and fast. If you are running it on carpet try to find a RC12LC chassis for it if you can, it ia a little thicker and has less flex than the L3 chassis. If you are running on asphault then use the stock chassis. Don't worry if you can't find a LC chassis because it isn't a must have thing to race on carpet but it helps.

If you are wondering what I am running for a car fight now it is an RC12LW chassis with the new style rear pod and t-bar, dynamic strut front suspension, CRC top plate (the one on the rear pod) and Trinity dampner tubes.
