I just tested the SNR RC8E carbon chassis last night. I attached a few pics. I use a protective film which was already dirty when I took the pic of the bottom side. Here is my review.

First, the chassis it top notch and the fit was perfect. I use several SNR products, and I never have issues with fit. It took a half hour to take everything off the old chassis and installed onto the SNR chassis.

I reset the ride height and took it for some laps at the local track. With 1/8th scale, any changes are immediately noticed. The decrease in weight caused the car to accelerate faster and be more responsive. The RC8 is already one of the best 1/8 scales when it comes to jumping, and it just got a little better with this chassis. I definitely noticed an immediate difference, and I really enjoyed the new driving experience.

If you drop weight off of your electric 1/8th scale, you get the best of handling characteristics of a 1/10 4wd like the b44 with the size and power of an 1/8th scale. I drove SNR's 1/8th scale which is well below 7lbs, and there is a huge difference in how precise and how fast you can be with a buggy this light. Not to mention, that primary suspension components that may have been prone to breaking tend not to break as often with a lighter vehicle.

As far as rigidity, generally speaking, carbon fiber is stiffer than aluminum (modulus of carbon tends to be higher than aluminum), and depending on carbon layup, the torsional rigidity is higher than aluminum. You can tune to your liking with various chassis stiffeners, but what I found was that the turning was a little more crisp and immediate without being twitchy. But this has a lot to do with set up as well as chassis effects.

Tested the chassis last night, and it took the pounding and kept on ticking. As far as fatigue, carbon fiber doesn't necesarrily have a fatigue limit like aluminum. The only draw back is how it fractures. Carbon will experience a brittle failure whereas aluminum will yield and bend. But I've seen Steve's carbon chassis on his hyper 9 take a serious beating for the last month and keep on going. Steve doesn't run any protective film on his chassis. Trust me, Steve and I are good drivers, but aren't prone to lawn darting every now and then, and I even went head on with another 1/8th scale going the wrong way without and visual damage to the chassis.

So far so good. Quality work from SNR as usual, and I will keep you posted as I continue to put the chassis through its paces. Oh yeah, did I mention how sharp and clean my buggy looks, especially without the chassis holes that were meant for gas power.
