I started on-road racing last year and had a M-07 Concept by August 2024. It quickly became one of my favorite cars. I did a number of things to make it stable and not want to swap ends like an F1 car without wings... I built the car with the 239m wheelbase... Longer = stability. Kinda hard to oversteer in a limousine, right? I had the 6* caster plate pretty early on in the build process. Tamiya red springs out back and kit yellow springs up front. Upgraded to TRF dampers (42102) and run 3 hole piston with 60WT (800CST) fluid. I run about 2* of TOE-OUT up front. It increases scrub and tire wear as a result, but it helps these cars immensely. I also have the metal parts for the diff, but I am using 1,000,000 CST silicone as the fluid. I'd be running the spool if they could still be easily / affordably had. I run the front swaybar only. Again, understeer keeps these happy on high-grip surfaces. We run the same tire setups F&R except I glued my front outer sidewalls and the outermost tread of the tire.

I've only ever bought a few items from overseas via eBay. I guess I'll have to grin and bear it to get a front spool for the TA-07

I've been into R/C cars since my first Hornet in 1986, but I didn't formally start racing until Feb. 2024 and I've learned A LOT in 14 months. That being said, I started with and still have a EuroTruck, but - especially in 2025 - the rules mean the front diff is essentially "open" with little to be done to control wheelspin. Then, in April, an opportunity arose to buy two (2) TA-07 Pro cars, so my friend and I bought them and we started the game from there. Up front, 1,000,000 CST silicone. Out back, 7000 CST silicone. After trial and error, along with help from some true professionals, we got those cars dialed in but the front diffs could still slip or perform inconsistently at times, especially under braking. Then, around August, I began to think of a proper FWD TC (by now I had bought an M-07 Concept to race as well. A guy who is sponsored by Mugen Seiki was selling his MTC2 FWD car *** WITH A FRONT SPOOL *** and he asked if I wanted to try it to see if I liked it before deciding to buy it. HOLY F-ING SHIIT!!! The car was leagues above the TA-07 Pro. Granted, the car is next-level, but the spool... OMG! Everything everyone said above is true. Sure, it'll push more, adjust your setup for it. Sure, it'll eat tires, but as someone who has autocrossed and done track days for 30 years, tires are as expendable as water in an aquarium. My race fleet now consists of the following... EuroTruck TA-07 Pro (1,000,000 CST up front) ***Can't find a Tamiya spool for it, or I'd be running one*** TB-05R (FRONT SPOOL) M-07 Concept (1,000,000 CST) ***Can't find a Tamiya spool for it, or I'd be running one*** MTC2 FWD (FRONT SPOOL) MTC2R (FRONT SPOOL) Regarding spools, to quote Mandalorians... This is the Way.

Here are some pics of my TB-05R. Tinypic keeps them here for a week, so I hope you like what you see. LOL! If anyone cares, I finished 3rd in the C-Main (GT2 was a stacked field with almost 26 entries) at a TCS event in MD at its very first outing, so I'm looking forward to seeing how much quicker I can make this car. (I also finished 2nd in the B-Main with my M-07 Concept). https://tinypic.host/image/20250309-213332.3aSb2v https://tinypic.host/image/20250309-213402.3aSAEO https://tinypic.host/image/20250309-213538.3aS4tm https://tinypic.host/image/1000008361.3aStfw https://tinypic.host/image/1000008362.3aSzNd https://tinypic.host/image/1000008364.3aS7ea https://tinypic.host/image/1000008365.3aS0RQ https://tinypic.host/image/1000008369.3aS6lE https://tinypic.host/image/1000008370.3aSWw5

Without using the debris cover, it is possible to run the kinds of pinion and spurs one would run on a belt-driven car such as the TA-07. Using 64P gears, I settled on an 84T spur with a 62T pinion (2.5 Internal Ratio) to get the new TCS-spec Hobbywing 21,5T motor to a FDR of 3.387. Car was awesome!

Looking to buy a used TB-05R for indoor carpet TCS GT2... I need to know what size spur and pinion this has to run in order to get the FD to around 3? I saw the internal ratio is 2.5 but I worry those covers will limit the sizes of the gears I can run compared to my TA-07 Pro. Any insight?

Hi all! Would any of you happen to have the 6* caster lower front suspension mount / plate (Tamiya 54780) lying around that you'd be willing to sell? They seem to be out of stock everywhere and my friend needs one to build his M-07 Concept for racing.

Hi all! I just installed a spool in my TT-02R (for TCS GT Pro Spec) and I know I need to get CVDs, but I heard the standard length (39mm perhaps?) are not the ones to get. Anyone have a spool in the front of their TT-02 and if so, what's your CVD setup consist of?

Found my issue. Thanks.

Up to this point, I have been using the Spektrum SLT3 radio with SLR300 receiver... Both perfectly fine for playing around as they're simple and reliable at a great price. However, after two official races (one was a TCS event), I realize the limitations of the SLT3 with respect to everything else, especially the braking modulation flexibility featured in better radios. From what I've seen, the Futaba 4PM, Sanwa MT5, and Noble NB4 seem to do a great job in the $200-300USD category. Should I be shopping those? Or is there something else the hive suggests? What do radios at $400-500USD offer over these? I plan on getting pretty involved with R/C racing as I've been racing real cars for 30 years and am going to start backing off that and picking up R/C more aggressively.

Thanks for the replies thus far, everyone! As for the ESC, what do you recommend to use that meets the letter of the following TCS rule? 13.3 No BOOST ESC (Electronic Speed Control) rules: Any ROAR legal, and approved ESC may be used, capable of “Blinky-Mode”. These ESC’s must not use electronic timing (boost). See General Rules for ROAR approved “blinky” ESC list.

In this instance, FWD... M-07 then. Thanks!

It seems to be a toss-up between the M07 and M08 although I see some say that the M-05 and M-06 can still get it done on certain tracks. I'm still new to R/C racing so I wouldn't be able to tell (yet) but I also don't know of many race series' where a 10 year old vehicle was still relevant, let alone feared. Yet, TCS rules for M Chassis cars seems as regulated as EuroTrucks (which I've raced once thus far and LOVE!!!) Suggestions?

Gotta be honest... In another thread on this forum, one asked what spares one needs to bring. For TT-01E EuroTrucks, I'd say something between nothing and a fully ready-to-go spare.
