Love to hear your thoughts about the carbon fiber chassis on high grip astro. With the CF chassis it just feels like it lacks control around the track. It feels very twitchy / sensitive. Overall it feels inconsistent especially around corners where it feels like grip is not linear. Both my RB6 and SC6 have aluminum chassis and they are very consistent and easy to drive -- but I love my D413 and would love to get some pointers.

Is stock CF chassis NOT the ideal choice for me, and would the AVID aluminum chassis be better for my medium sized high grip astro track? Is the price justified?
I also ran my D413 with the stock carbon chassis on astroturf, and the traction was very inconsistent and the car was very difficult to drive. With the amount of traction available, the carbon chassis will flex a lot, therefore explaining the car's handling characteristics. I am convinced that the AVID aluminium chassis will transform the car on astroturf. I have bought one, but I have not tried it yet. I think you should only be running an aluminium chassis in a 4wd buggy in high grip situations.

Takes a little play out of the front.
Which Finnisher JC kit did you steal your turnbuckles from? Obviously they seem to be a great fit.

Maybe I'll wait for this as a solution for higher grip astro tracks. Any guess on when this will come to market? Or should I just get the Avid aluminum chassis in the meantime.

These parts should be currently available as team drivers have had access to them for a month or so now...

Drill a hole in them and ziptie them to the spring. Also keep the slot in them facing to the rear, they won't come off as often. Exotek makes an aluminum set that seem to stay on better

Any idea where? I can't find the caster blocks anywhere online.

4wd on Astro is a LOT more direct than indoor clay from what I have experienced. Regardless, I found the Avid chassis a lot more stable and predictable than kit, esp with the brass weight in the rear.

Diff oils tuned to suit, my preference is 10/300/7. Copper front roll bar, silver rear. Go to silver front if very grippy. If you mount the front shock tops on the inner hole, the steering response should be more predictable/docile. C/F wishbone inserts all round. Tyres on Astro also make a huge difference, what are you running?

I've just picked up the schelle +4 alloy chassis to run this weekend so we'll see how it behaves; currently pitches around a lot on high grip which can make for a challenging drive.

Btw, I race in the UK.

I suggest contacting HPI directly and see what they say, they should know where they have been shipped.

Will do thanks!

On another note, are most guys running glued plastic inserts in the arms on med bite clay or cf?

Greetings and thanks for the advice. I have a sneaking suspicion that you may know a thing or two about setting up for Astro : )

I am running Schumacher yellow mini pins on all fours. Please let me know about the schelle +4 alloy chassis. I may consider that as well. Also thank you for the tips above. Cheers!
