At WCRC I'm all the way down to almost a 3.0 with the Icon 21.5 motor, as are most guys.

NEWS: WCRC is now allowing the FF03 in Super GT, so WCRC and CAM are basically running the same rules package. Don't know if they'll allow other 2WD setups, but that's rare anyway.

Sounds like a great class. To really be successful it would be good to contact manufactures and see if they're willing to put together a low cost RTR. If this happens a class like this could really take off and maybe bring people back to on-road racing.

Magazine coverage would be good to.

On the TC5 what gears will get me to a 3.0-3.5. I just bought a 76s/47p and they do not touch.

Somebody on our forum just posted 90/55 for a TC5 yielding an FDR of 3.27.

Is 90/55 in 64p. Does it matter if its 48p or 64p. When I go here http://www.comeseethis.com/gearing/Default.aspx I can not tell if its 64p or 48p

i would expect it to be 64, a 90/55 in 48 would be 120/73 in 64 which sounds really big and hard to fit

if you did have something that did fit, then try staying close to the same total teeth. (pinion+spur)

its a geometry thing, the radius is proportional to # of teeth, so swapping tooth for tooth from spur to pinion should keep the clearance the same while lowering the FDR.

It's 64p.

Pete,

Have the Road Runners contacted other So Cal tracks or race organizers to put these rules in effect for the SGT and SGT+ classes?

My concern with taking FF03 and going brushless is NOT a cost effective alternative. The FF03 (non pro) comes with a motor. Why toss $15-20 away? in favor of having to spend $80 for a motor? ESC's can arguably be the same in price but from what I see a brushed ESC is near half the cost?

Also I think that a FDR rule needs to come into effect. The FF03 is just not equipped to handle the rediculous pinion to spur ratios without major (very fluent hobbiest) modifications and extra parts.

Staying with "silver cans" in this "All Tamiya" class anyway (for now) will allow it not only to stay low cost but also TCS legal.

Perhaps if this class gets more manufacturers involved then move to a 21.5/zero motor rule. But for now while the class is growing....

Just my $1.389

^good ideas, opinions are different though.

brushless combo= cirtix $80-100(90+ for "nice" motor alone, ie open 21.5 motors)
brushed esc= $40-50+
Starting out yes you save using the stock silver can. But you end up spending almost the same amount after you buy another silver can when it wears out. Brushless esc/motor quality would be higher and last longer. Run with less heat etc.
Those who have silver can prefer silver can.
Those who have brushless/cirtix prefer brushless.

Spec FDR is good idea, but imo it needs to include buy out option or rpm limits. IE, your motor can be bought out under you by another racer at full retail while the race organizer has it in stock.

What does VTA set their FDR's at? I like the idea of setting FDR's, but would you also have to set the timing on the motor?

Racecrafter, I had my doubts about brushless, but the more I run it, the more I like it.

Worrying about TCS does not make sense as it reduces the # of chassis available for the class tremendously!! This is a 21.5 BRUSHLESS class---designed for REALISTIC looking race cars and slower to help rookie racers. You don't need to go out and buy a new car for this class---there's a huge # of older TC chassis that work great for this class---that can be purchased for far less then a new Tamiya car.
The new FFO3 cars have been allowed to run--because they also have the correct bodies usually, and have been found to be competitive if setup properly. BUT---they already have their OWN class to run in. Changing SUPER GT is not necessary for them to remain TCS legal--they have a class designed for them.
This class has shown great response and is growing---STOP tinkering with it before it has a chance to grow bigger. CHANGE is not always best---leave it alone! Simple cheap esc's and 21.5 motors make you competitive if you learn to drive. Solaris tires last forever, I've got some with over 40 runs on them still working fine!

So no one can discuss ideas? I don't see anyone trying to make immediate changes to SGT; People are giving opinions and others are commenting...Kind of the standard discourse you find on the internet.
