Tried the new Dart and it is a bit better for me but i still think 17.5 T LTC is where it is....
Hey Gordie,
Are you running Carpet or Asphalt?

Just finished the Ontario Triple crown series..!!

The Samix carbon v2 chassis felt really good. It adapted to the traction change as th weekend went on. The small changes kept the car consistant for me !

Took the overall Series Win 17.5t blinky . Going to race the same setup i have in 13.5t blink and see if it can handle more power...

Default Chassis

how different would the Samix v2 carbon chassis be compared to the Aluminum one?

I'm super happy with my alu chassis on asphalt but it's a tiny amount bent now, considering experimenting with a soft carbon chassis now. Not too sure how much the slight bend affects handling but if I push the rear end down, the front moves up maybe 2mm

in theory it will be completly different.

I havent tried it back to back on 418... but on the 419 i felt the alum was far more stable but had a slight push...

I would think the Saxim Carbon would give you a more aggressive front end so you may need to adjust setup for the chasssis...

RCmart has them in stock or check them on facebook I love the floating spur mount for stock racing,,

I ordered a Samix aluminum chassis to try on carpet. I thought the carbon chassis'ed 418 was pretty decent on carpet, but a little subpar on asphalt. Heck, the aluminum chassis feels like it has more flex than the stock carbon chassis. I would think a softer chassis would help the car on asphalt, like Gordie says. We'll see how it goes on the rug with the aluminum one...

I pretty much just run stock setup with alu chassis and front diff with 2.5million on asphalt. Gained traction and some turn in steering which is quite helpful especially on a hairpin right after the straight

The Samix conversion helped me slightly in the lower grip asphalt that we run versus stock carbon. This is only 17.5 racing though. I'd imagine for mod, the difference would be much bigger (and more positive).

I happen to have some roche dcjs 45.5 lying a around.. would it be of any use to run these in the rear? my stock alu driveshafts have some slop in them now.

also, how is the quality of STRC titanium screws? I have a set for another car I thought about donating to this car.

If i'm racing in onlyl 17.5 or 21.5 blinky, would there be any performance improvement in switching to a Samix graphite Version 2 chassis conversion kit? Or am I better off leaving it as is with the stiffer Tamiya chassis?

What surface are you running on? Carpet, asphalt? Low or high traction?

I'd stick with the stock chassis on carpet, as stiffer is more desired when traction is higher.

I had the same thought that the stiffer chassis would be better then the Flex carbon from Samix... BUT...

I am a believer that the car gained overall traction and changes i made to the car were more noticable...

So for me Samix Carbon stays on the car... even at high traction!
