I wanted to give some input on this, as I do have a lot of experience on using carbon fiber chassis on nitro based cars. Over 7 years... I do not run one on my car only because I have been told it was not "ROAR" legal when I was doing testing at Kissimmee back in 2006 and I have not taken a serious approach to this, but I do have a current NT1 with a CF chassis in my garage.

I have been making these for 3 1/2 years now, going back to the MTX4 MTX3 (more...read)

Actualy it is a good idea. I took and built a carbon fiber chassis 4 years ago and ran it at Kissimmee. To test it, I drove the car head on into the wall at the back straight, FULL THROTTLE.... the car didn't break. I also tagged many areas on the track during my test....the chassis will "flex" and return, but it will retain a memory after prolonged accidents, much more than an aluminum chassis will take)

Furthermore you need the aluminium as a heatsink for the engine, with the carbon i think the temperatures will rise with a 10-15C.
Correct, the CG will get higher
Yes/No.....Carbon fiber is an excellent heat sink/disipitator.....that is why they use it in motor cycle exhausts, run for hours and yet cools down quickly.
You can argue this in two ways...the engine ran warmer.....maybe it was turning more RPM's? It didn't have to pull as much wieght>car will accelerate much faster...

The carbon fiber chassis does not allow much side flex, like the aluminum chassis. It will take all the abuse the the aluminum chassis will take, and if you his something hard enough to bend the aluminum chassis, the carbon chassis will "spring" back, but it will retain a "memory" We found this out in Oval racing Nitro Pan cars in GASCAR. (3 years experience with this)

How hard does a pan car hit? With no bumper!
NO, but YES.... Again, this has been tested by me and some other racers around the country that I have sent chassis to over the years. Industrial grade carbon fiber is very brittle and does not like "shock", but thier is a better grade of carbon fiber that is cross weaved, called "Quasi-Isotropic Carbon Fiber" and is used in many automotive structural applications. It has a life span of 15+years in such applications. The chassis I made were made from the Quasi type and took a tremendous impact at 50+mph at Kissimmee....
