In San Diego, The Lap Factory and RC Racers run GT Spec with TCS rules including the Reedy 21.5 fixed timing motor and 5.74 FDR (RC Racers i think allows 5.2FDR). Spec tire is USGT Gravity's.

Its a fun class and good for beginners after they graduate from rookie. I think its a perfect class to get them ready for USGT.

My local club runs the TT-01 / TT-02 as a spec TTGT class.

TTGT - Tamyia GT
The focus of this class is to provide a fun and cost friendly option for new and established racers to compete. FUN is the key here! If you feel the need to spend a lot of money to race, then this class is not for you. Note: Steel Drive shaft conversion will be permitted on the TT02 chassis only.

CHASSIS: stock TT01 / TT01E or base TT02 ( B/D/T/S/R/RR variants NOT permitted)
ESC: "Box stock" Tamyia ESC as delivered in the OEM box
TIRES: Gravity Racing USGT spec tires on spoked rims ( using the kit wheels with USGT tires is permitted ) only the foam insets included with the USGT tires can be used, double stuffing or alternate foam is not permitted.
SERVO: no restrictions on servo; any servo saver allowed BODY: see list of approved bodies. Nothing else allowed.
WINGS: Molded plastic (no lexan wings) and only what came in the kit - NO non-OEM wings may be added.
MOTOR: Tamyia brushed Silver can 540 Torque Tuned motor only (54358)
BATTERY: 8.40 volt, Lipo 2 cell, 8000 MAh maximum. Full-size stick or brick batteries only; no 8.6 volt-capable batteries – no shorty packs-no soft cell packs.
SHOCKS AND SPRINGS: Must be Tamiya friction dampers and chrome springs that come in the kit (TT01/TT02). (no oil dampers allowed)
DIFFERENTIAL GREASE: Open; any lube or grease may be used provided the differentials are not locked, no spools, no glue-welded diffs - (must function as an open differential)
MINIMUM WEIGHT: 1450 g
ONLY Allowed Modifications
* Hex steel screws may be used in place of the OEM Tamyia screws * Nylon bushings maybe replaced with ball bearings
GEARS: Tamiya kit spur gear only; pinion can be any manufacturer. TT01 must use (48p/0.6
module) 19t pinion with kit Tamiya 61 spur =8.35:1 FDR; TT02 must use (48p/0.6 module)
22t pinion with kit Tamiya 70t spur = 8.27:1 (this is the closest matching FDR between
chassis)
* Any Battery connector is allowed
* Chassis ribs on TT01 models may be removed to allow a standard rectangular Lipo batteries to be used in TT01 chassis
*please note: modifying the tub in this manner may exclude the car from running this spec in events hosted by other clubs
*Shims permitted to adjust for slop in suspension or steering but not allowed to change the
geometry of the car.
Some kits can be built with a wider configuration or adjustable ride height. If it is in the
manual, it is fine but must match the body. Example, no wide configuration if it pushes outside the body.
* Tire sidewalls and tread may be glued

This thinking ruins spec classes, set guidelines and stick to them. Allowing hop ups and gearing changes will just spread the cars out and make the racing boring. The rules listed above by SteveM are the same as my club and all the modifications that should be allowed. Let's not destroy a good entry level class, emphasis should be on getting better as a driver instead of just building a better car.

Finally finished up my rally body for the rally/drift TT02. Waiting on another set of the same wheels to come in to use for the tarmac setup so I've got matching wheels. 13.5t no-name brushless finally shipped. It's got adjustable timing at least lol.

It's hard to see the flaws when it looks so good

Came out better than expected

Dirt setup

Tarmac setup

I do agree with this. I don't think it could be considered entry level with loads of hop-ups allowed. This kind of takes away from someone being able to jump in and be competitive because everyone is using the same entry level chassis.

I agree partially with the hop ups. While it can be argued that aside from a few hop ups, they don't add much of an advantage.

The flip side is that those more experienced can use those hop ups to thier full advantage while others may struggle to keep up.

I think it should be stock for stock. Minimal hopups for an entry level class.

Then make a modified class for those who want to move up and upgrade.

The GT Spec Novice class is for beginner drivers only. This class is perfect for new drivers that have little to no experience, and just getting into R/C racing. Intermediate, Advanced, and Expert drivers, are not allowed in this class category.

Recommended Skill Level: Novice Only

10.1 Legal chassis platforms: TT-01, TT-01R, TT-01E, TT-01R-Type E, TT-02, TT02S, TT-02SR, TT-02R, and TT-02RR (TT Series)

10.2 The GT Spec Novice class may use any Tamiya Hop-Up-Option designed specifically for the platforms allowed above. Recommended: Ball Bearing set, Speed Tuned Gear Set, Aluminum motor mount, and Oil-filled dampers. These 4 Hop-Up-Options are all you really need.

10.3 Motor: You must use the kit supplied motor. (Mabuchi/Johnson) 540-J and RS 540 Torque Tuned motor (items 54358 & 53689) respectively. They come with all TT kits. See General Rules for Motor RPM limits.

10.4 Tires: Any TAMIYA rubber tire, and wheel, may be used. 24mm, and 26mm width wheels/tires, are permitted.

10.5 Legal race bodies: Any Tamiya 190mm GT, or Sports car body is permitted.

10.6 Minimum weight: NONE

Ill have to disagree with you there. Please read Tamiyas Spec Novice rules. It allows for any Tamiya hop up for TT02. They are accessible to all and None of which will give anyone a great advantage.

My 8 year old has raced Spec Novice for 4 years with TT02-S that is TCS legal. It’s hopped up for durability. It didn’t give him any superior advantage until he turned 7, when his driving skills really kicked in and he placed first in April.

The TT hop ups are mostly bling, makes it fun.

The rules your talking about are the TCS GT Pro Spec class is actually not a Novice class. It’s dominated by experience drivers battling it out for that extra 0.1 second.

Attend the next TCS race and enter Pro Spec and see how you do.. it’s tough. I raced it last April and battled for 3rd and eventually succumbed and placed 4th

I always thought that TT-02s in R, RR, S and SR usually don't come with any motor...

They don’t come with a motor. You would need to pick one up to run in TCS

FWIW, my club created those TTGT rules to 1) keep the cars as equal as possible, and 2) to keep initial costs as low as possible. We need more people to come play and cost is a barrier for many.

I totally see your point. However without hijacking the thread I'll just say that legal mods turn to illegal mods real quick and then you have policing issues. Sorry but I think we've all seen this kill good classes. Stick to the pogo springs and 99.9% stock cars and just keep it fun and affordable. If you want bling just run touring car, onroad needs cool spec tamiya classes like this and euro trucks.

Hi guys, Received my TT02 yesterday and most of the parts I ordered. Can't wait to start the build.

Thank your for the good info.

Does this mean you're coming to play this Sunday? :-)

No, not just yet.

And to clarify, those rules were Kingston's, Ottawa piggybacked us on purpose to create commonality between clubs.
