1/12 forum
Hey guys.....someone in the buy/sell section was selling a tekin B1....the add stated that he had been using this speedo for stock 1/12th racing. Can this speedo handle the 17.5.......and if I'm asking in the wrong thread...let me know where I could find this out(I looked on team tekin's page the B1 advertising says up to a 380 size motor?)??
Thanks,
Roy

Has anyone experience with GRP 1:12 tires? How do they compare to Jaco tires?
Any differences in rims or other stuff (e.g. offset, foam quality) that I should be aware of? I've been very happy with Jaco tires, but GRP tires seem more readily available where I shop these days.
Thanks.

I've been using Parmas for years and like them a lot. The wheels run straighter than any other brand. Parma/GRP don't have as many compound choices as Jaco but I can always get the car to work with set up changes rather than the small difference, say, between a Lilac and a Purple. Parma rear wheels have less offset than Jacos, at about 2.5mm compared to a little over 3mm for the Jacos. Front track will be slightly narrower with Jaco fronts compared to Parmas by about 1.5mm

Gearing all depends on the track you run at. I would say ask the racers at the track you are going to run at for what they are geared at. Also alittle more information on tha track you run at would help abit so someone can chime in on where you should start at as far as gearing/rollout is concern.
Our track is indoor asphalt with med/high bite...our back straight is like 100-110feet long. Thanks in advance!!

Odpurple: thanks.
Another question. GRP tires seem to be specified in terms of shore rather than color. Which shore corresponds to which color? Does the following correspondence seem correct? 30 shore = gray, 32 shore = pink, 37 shore = magenta, 42 shore = purple?

Well, I have finally pieced my CRC CK3.2R together to the point where I can start contemplating electronics. Seeing as how I have never raced 1/12 scale before, I plan on running 4-cell stock. I have a Futaba R133F receiver and S9601 steering servo, however, I'm having trouble deciding on a motor and ESC. For the time being, a brushless system is a bit beyond my budget so I'm looking for a good brushed stock motor; the Orion Core Stock and Trinity CO27 Pro, in particular, have caught my eye. As far as ESCs go, I've been looking at the LRP QC3, Tekin FX Pro, and the Novak GTX. I'm just not quite sure what is best for my application. Would anybody care to offer some advice?

Another question. The new Jaco tires are made for flanged bearings. What is the size of the flanged bearing? Are both bearings in the the rim identical?
Also, do you guys run double pink fronts and pink rears for modified on carpet as your main choice? Does this work when the carpet has a lot of traction as well?
Back in the day I ran purple fronts and gray rears, but times change it seems...
Thanks.

Purple/Grey is actually for stock racing, although Yellow and Lilac are often used as well. For modified Dbl Pink/Pink is great, but in high grip situations it will lock in the rear of the car and make it push.
Depending on your axle, you either use 1/8 x 5/16 flanged (Associated front end), or 3/16 x 5 /16 flanged (CRC front end). Yes, both bearings in the front rims are the same size.
