Hi everyone!!

Getting back into racing from a 15+ year break and have picked up a 2016 X12. Back in the day I was a Trinity driver mainly racing the old Trinity 12P Revolver in 6-cell mod on asphalt (never raced on carpet). Also ran a Trinity EV-10 as well. The X12 will be my first non T-bar car. I won't even get into Lipo and brushless motor confusion :)

During my break I've been racing sports cars, mainly vintage Porsches.

I will be racing at N-Control here in Austin, TX (http://ncontrolrc.com/facility/).

Are there any idiosyncrasies I should no about? Guessing tweaking is the same just adjust the side springs to get even lift of the rear wheels.

I have printed out 2 of Ed Clarks asphalt setups as a starting point.

Anything else I should know?

Thanks,

Ned

I think the tweak is the only real major difference from the old t-bar style cars, aside from setting rear ride height with shims now. You are correct with the tweak process involving preload on the side-springs. I have not run the X12 on asphalt, so I can't be much help with setup. I seem to recall a few years ago guys were using paragon ground effects and suntan lotion on the tires. Not sure what they use these days.

Hopefully I will see you at Nats!

Robbie, thanks for the response. Unfortunately I won't be at Mats as my son plays college football and that is opening weekend. Most of my fall weekends are tied up with football. I

I may make it out to watch on Sunday afternoon.

Ran a couple of packs through the car on Sunday. Not enough people showed up to race (heat) so just a practice day. First time in about 20 years to run a 12th scale and did OK. Very consistent lap times.

However, gearing is way off. Brushless motors and Lipos are way different than brushed and NiMH :)

What 70T 64P spurs will work without having to get new diff balls?

Xenon Racing makes some of the nicest gears in the industry and they have everything from 70T up in 1 tooth increments. RW Racing also made really nice gears but I don't think they are around anymore. Those are the only 2 brands I ever run in 1/12 because Xray does not make one that I'm aware of. Xenon and RW are 2 of the highest quality brands I have seen to make 70T spurs for a diff.
