Oh trust, me, it is not fast at all. Very comparable to a 21.5 current generation.

But we are starting this up here to use the class as a bit of a stepping stone into 12th scale and it's working fantastically. With the FT motor, a fixed gearing and rubber tires....the class really becomes something that won't overwhelm a new racer or even an old one just getting into 12th scale. They can focus on driving and how setup affects the car.
thanks for the response, I see it definitely is a stepping stone for 1/12.
Here at our club there is no other rule for motors other then it needs to be 21.5, and the gearing is open too. We only have 3-5 guys at the moment, 1/12 17.5 LMP is the most popular class tho

I guess it's a matter of perspective. Compared to a hot 17.5 it is slow. Compared to a USGT motor (or equivalent) it's fast.

the one time I’ve seen GT12 run. There’s was about 1.2 seconds slower then the 17.5. Laps of 7.1 vs 8.4 second laps. I’m still a bit off that pace
I’m assuming they were using the USGT motor. But didn’t see them to confirm(damn auto spell)

We ran a mixture of 21.5 and the HW FT for a while and really didn't notice a lot other than the 21.5's having a lot more grunt. A really good 21.5 puts the HW behind. Those HW FT motors are pigs...which is perfect for this class imo.

Could be a product of the fixed gearing too....we ran 72/40 at the time. I might add, that gearing is a bit of a problem with the CRC cars.

If your having gear problems try the RW spur gears. I have a 66 spur on my CRC GT12 and have fitted a 67 pinion. These gears of course won't take the small CRC balls but work just fine as spool gears or use 1/8" balls if you run a diff.

the gear problem on the crc has to do with running a 72/40 fixed gearing. The crc motor mount doesnít allow this ratio to mesh. If you go with a bigger spur and pinion to get the same ratio, the bigger spur gives a noticeable advantage. So far, that chassis is the only one that has that issue.

My bad, didn't realize your issue was going to less gear. Most people work to get to larger rollouts not smaller but I can see your issue. Hopefully your local race director will change the gear so all makes can be included. I'm guessing that Awesomatix drivers are in a similar spot, their car has a really small adjustment window for gear selection,

That is why we ditched the Gates original fixed gear rule. We had a 56/72 setup which didn't fit the A12 nor the X12. Lets guys have some tuning options and learn.

I get that there are supply issues, but Scotty could reply to people. I want to support this class and his efforts, but a little customer service... an update of any kind... would go a long way.

I feel you on that. Granted I am very thankful he does, but itís confusing to me that I have never had an issue with communication with him and many others have.

Default Getting started...

New to electric on road and thinking GT12 is the right place to start. Sold all my nitro onroad equipment 12 years ago but ready to get back into the hobby.

I like the xray x12. I have looked for used options a little bit but my preference is to build up a brand new kit and learn the details of the chassis along the way. Here are photos of the setup I'm planning.

The club near my house is running the 21.5 in these. Below is a screen shot of my wish list so far. What am I missing? Im mostly unsure on servo. Body, wheels, charger, will be determined later. Am I missing anything else? What would you recommend and/or change?

I like the M17 radio myself and the white carbon battery from Trinity. Great servo. The HW 209.00 I believe has the better battery protection (in case you put the plugs in wrong).. Bodies and tires are your choice.
