Ok, so after some discussions with various people, I've got a candidate for a spec 12th class, and I want to do some testing.

The idea is 10.5 zero timing on the ESC (1S packs). There are some spec motor and ESC combo deals around for this for various other classes, so that's a plus. Also, a 10.5 with dynamic timing is a decent first Mod 12th set-up, so making the step up would require no new equipment.

Like I say, I'm going to do some testing to check the speed and driveability for new people, and I would like some starting suggestions for rollout/gearing.

There are two tracks in my area that race 12th. One is a largish, very open outdoor track, the other is a tight indoor track running on astroturf (like carpet but about 75% of the grip and less consistent). So, if anyone has any experience with zero timing set-ups for 12th I'd appreciate it if you could post the rollout and the type/size of track you are driving on.

Anyone with direct experience of what I'm going to try, it would be great to hear your thoughts too.

Thanks.
