I was a bit surprised when he raced at iocc myself. I’ve also noticed since RM has joined the team Lee Martin started doing it as well at carpet races. Lee has also ran the car without the front chassis braces. I always thought stiff car for carpet. For what ever reason, it works for the yoke.

but on road tires and off road tires make a difference.Half the width and less grippy compound. I'm just thinking out load here. If the chassis can flex a bit more torsion-ally? Twist I guess is what I mean. During hard corners/transitions, it would put less strain on the front tires initially by allowing the back to say flatter. Guessing it may be quicker in like the "S"'s and switchbacks.......maybe?
During rear motor days though that would have exaggerated the swing arm effect even worse.

Hey everyone. So I'm going to try 2wd again. Been running 4wd for a year now but always loved my old yz2 ca I used to have for indoor carpet. There's no more carpet tracks around, only outdoor real dirt (low, med grip at best) Which of the models will I be best off with? There's too many now it's confusing... dtm, dt, dtm2, worlds edition??

Probably makes it easier to drive for him.

That’s what I find odd. I thought too much flex, too much grip = less corner speed.
But we’re talking modified power so maybe it does take a bit of the edge out of the chassis!

I tried both (regular carbon strap vs taped shorty) on high grip astro.
On one particular section of the track with two corners, bumpy track and some elevation I noticed the car without strap is quicker to recover mass transfer (flex) from each corner and able to come out of the section quicker.
It is not so much as the chassis flex at first but more how the chassis recover from the flex.
With the strap it feels like the recover is very quick and in that section you have to wait a bit or you will roll over.
With no strap I don't feel that recover as much and I can carry on and out of the corner much faster without grip roll.

Interesting! Thanks for the info!

Even running on super 100% clay like I have here locally, running the brace makes the car really twitchy. Taking it out calms it down a lot especially on high speed sweepers.

You're still running the new style waterfall brace, correct? Or no waterfall?

Also, I have the DTMW, can anyone point me in the direction of a good setup? I've looked at Petit and there are tons of Astro setups, but I'm not familiar with the differences between all the versions yet. I've added a gear diff, anything else I should add to make the car better on Astro?

The Worlds car already has the graphite and wide rear suspension parts so you should be good to go. Sway bars may or may not be required depending on your track.

Cut Waterfall but I've tried to tape others 2wd too.
Just a bit worried running mod to bend a chassis.

Take a look at Lee Martin setups, they're usually spot on to start with depending on the track (astro on flat surface or astro on bumpy dirt/multi surface, long pile vs thin astro, that will change a lot to the setup).
He will put a new one out build around the CA2 soon I guess.

depending on size of track and motor.... TSR,motiv,MC2,Fantom, are all real torguey motors were as the new tekins are higher rpm. I have a TSR but not "the one" an am running 31/72 on a smallish indoor dirt track

Got the wiring done. Decided to just Velcro the battery in because the strap was not cooperating with the short Lipo and it also looks a heck of a lot cleaner.
