Those number you gave will work for European and USA grey carpet where bite is low.

The numbers that I gave are best starting points for here in the USA on black carpet.

Yep, chassis had rounded edges and glue.

There goes away the strength of the chassis beneath the screwhead, even overtightening the screw will cause delamination...
Oh well, I'll mill a new chassis with holes for a xenon front end. But its a shame really, havent broken a single chassis in my 25 years of driving onroad rc.

Did you glue the screw holes?

I think 700-1000 is too soft.
1:12 drivers in my area have come to the same opinion as @ Max K.

I first test with 10k, that works well. For more test I have bought a second diff and will try harder oil. I'm curious

That one I didnt, never had to do that before on any of my other cars.
Everyone who's seen the chassis states the same as me, there was prolly something wrong with the carbon fibre. A bit of ca glue on the inside of the screwhole wouldn't have helped much I'm afraid.
The arm should have broken, not the chassis.

The car was slightly less aggressive, but I had no change in lap times. Maybe some more testing was needed. Strapping the battery in was a pain though, and for the convenience of the o-ring and the fact that my lap times didn't increase I switched back.

Here is a pretty good starting setup for Can-Am Stock racing with CRC spec tires. This is the setup I used to TQ and Win Stock Wars this past weekend. The car was very good every time I set it down, didn't matter if it was fresh tires or 4th run on tires. Super easy to drive and consistent balance the whole 8 minutes. Grip was medium-high, not greasy. I did not cut the back of the body real short like some guys are doing as I didn't feel it was necessary.

Thanks Steve!

Also, to add clarification I run the battery all the way back. That part of the setup sheet confuses me and I most likely clicked the wrong dot. I always run the pack all the way back.

I read that it was on the king pins but totally read over the tubes. My bad

Here’s a shot of my arm setup. This pic will show how the upper arm mount is attached to the lower carbon arm, and how I have the lower arm attached to include arm sweep.

for the upper arm mount to work as shown, you should swap the carbon piece left to right so you can still use the countersink screws.

What was your caster? The steering blocks are so perpendicular to the arms. Mine are angled back, but I haven’t done the arm flip mod either.

I was running 3* then moved the arm .5mm more forward but didn't re-measure. I'd guess around 1-2*.
