If someone new wants to start racing and they get into RCGT and have a blast and want to then move in to say ROAR sportsman class but the battery pack they first picked up was a non-ROAR approved pack they now have to buy another pack to move up a class. The same thing for someone who is looking at RCGT as a second class. They probably have a ROAR pack or packs already but are now in a situation where they will have to buy another pack to race this class. The class needs to be as cost effective as it can.

Really what should be happening is we should be pushing ROAR to make the sportsman class RCGT like....meaing using the Sportsman rules just open the bodies to all the cool looking bodies. Then I really think the class would take off. Too many people are looking at RCGT and think its only a HPI promoted class.

Also the C rating is really meaningless with the limited ESC's and 17.5 or 21.5 motors. You are never going to pull out a high load to take advantage of the C rating. I think there is too much weight placed on the C rating of packs. Racers are always about numbers and when we see a higher number in a battery pack we assume its instantly better. But the problem is there isn’t a real way to check this C rating over 30 or 40C. I mean really I can start to sell packs at 100C rating but if no one has a machine to check that they can handle 100C it’s never going to be proven wrong and guys would be lining up to buy them because of the higher number.
Guys this was in process within ROAR prior to your threads and the activity has been noted. The rules here are so similar with the batteries change you would not believe but again I like what i am seeing here. Great thread imho.

probably won't make a difference until 13.5 using a tekin.

Rocketron, having read all 60 pages of the rcgt usa thread that CharlieB started, I was amazed how much of the process had been started or talked about before. Luckily the interest was still there to finally make things happen.

As a matter of fact, if all goes well I'll be running my FF03 with the 4WD cars this Sunday, with all other specs being equal. I'll be sure to post my findings here.

I have personnally run in RCGT and have been working with HPI as well. I believe this can be a solid sportsman class. Should stress realistic looking bodies and imho be 21.5 non-timing ESC's. This MAY allow the newer racer to hang onto the car. Bringing in NEW racers is what this is all about, maintaining also being a factor.

I know. In fact, our track will probably differ from these rules greatly. I am just putting out an argument on behalf of the rest of the country that will run this class.

Thanks Austin, We hope the rules allow enough room for as many people with various skill sets and budgets. The rules now give the clubs and organizer some room for flexibility and yet be able to promote the spirit of the class. It happened with input like yours....Thanks.

1. Bodies: Any 190mm or 200mm realistic GT type body (no touring class racing bodies such as Stratus or Mazda 6). Molded kit wings or aftermarket wings are highly suggested. Lexan wings must be of proportionate size. Lexan wings are not allowed in Concours.

2. Tires: HPI X-Pattern tires, part #s 4790, 4490 and 4495 are the official spec tire of RCGT. Alternate tires may be used at the race organizer's discretion, but all HPI supported RCGT events will use the x-pattern tires.

3. Inserts: For HPI X-Pattern tires the stock insert must be used. All alternate tires choices may use any insert. Race organizer may define specific choices.

4. Wheels: Any REALISTIC spoke type 26mm wheel may be used. No aero dish or lightweight racing wheels allowed.

5. Motors/Esc's: Any 21.5 or 17.5 brushless motor/esc as shown on the ROAR Sportsman list. In addition, the Speed Passion Cirtix 21.5 and 17.5 are allowed.

6. Chassis: Any 1/10 scale all wheel drive touring car chassis. Minimum weight requirement is 1475 grams.

7. Batteries: Any Lipo 2S packs up to a maximum of 5000mah. Hard case packs are highly suggested.


We all hope the revised rules will help everybody continue to enjoy the RCGT program. I should also say that we'll do our best to consider and make revisions when necessary. We can't plan for everything but we'll try and catch up to them as quickly as possible. Thanks again to all of you !!!!

I posted the rules again after reading your post. Kinda wondering if you had seen them since everything you're looking for is pretty much there aside from making 21.5 the standard. But keep in mind that any group can make 21.5 the standard. My club has. We won't run 17.5 unless we get enough racers that wish to run it as a expert class. Just a note for those that may not be familiar with the ROAR list. The ESC's specified must have the ability to turn off all timing advance or boost and must be clearly readable for tech purposes. Hope that helps. Please let me know if for some reason it appears the rules aren't clear on these points.

With a Cirtix I would imagine your FDR would need to be in the high 2's/low 3's, since they are running into the low 3's with the 17.5 Cirtix.

Hey Austin, Like M-Technic said I wouldn't be surprised if you had to get into the low 3's. It depends on your track though. On our track of about 80x40 we usually run in the 4.5-5.0 range. The 21.5 has great torque for corner exit acceleration if geared right. We get temps in the 110-115 range with the Ballistic/Havoc combo.

For those of you that care.

Here are pics of the Blast Off tires, We will try to test them out on Wednesday night.

Pictured for comparison are Solaris Spec Premounts, HPI D Compound X's and the Blast Offs.

Dim's

BO 26.25mm Wide, 66mm Dia
HPI 26.00mm Wide, 65.50 mm Dia
Solaris 24mm Wide, 62.00mm Dia

Maybe I am simple, but not sure how to measure the offset.
