Default Carbon chassis?

Hey,

What would happen if I made a carbon chassis for my 1:10 nitro, would it kill the engine or ruin balance due to weight loss?

Has anyone tried that and failed or succeeded?

I believe heat is disipated through the aluminum chassis.
I know my chassis is quite hot after a long run. Might need to find another way to bleed off that heat.

I have worked with this for about 3 1/2 years with a touring car and also another 3 -4 years with pan cars. Look at this link to answer some questions........ I have done this for the MTX3 MTX4 and the NT1 with success and without having a temp issue....actualy lowered the temps because of the disipitation of the carbon fiber. Even when cutting the carbon fiber dry with high speed tooling, it remains cool to the touch.

I actually still have the MTX4 carbon chassis that James (rcfoolz) sent to me for testing. I was almost positive that I would engine temp issues but I didn't. Now, I will say that without changing anything else my car did traction roll a bit easier than with the aluminun chassis.

My guess is that if I had done some other setup changes I might have been able to make the car good. Also, I was running on a high bite VHT track at the time. With a low bit track, the carbon fiber chassis might have actually been better.

Thanks, but what is the link?

I would stick with aluminum.... The car is gonna be top heavy not unless you add weight back to the chasis which defeats the purpose of CF chasis...

CF also tends to delaminate when it is dragged enough and It will eventually splinter....

100% correct, it will delaminate.

When I built the first one 3 1/5 years ago, I had a source on Associated Chassis Protector, a .5mm thick sheet of teflon that covered the chassis from front to rear. The car that I had built it for had more mods done to it so that the wieght of the car was lowered. Some may remember some of what I had done. I had lowered the radio deck 2mm along with the fuel tank an additional 2mm (4mm total) and the bulkeads had been modded for 1.5mm lower stance at the bottom along with everthing that attached to the top was lowered an additional 1mm, making the car thinner than the current NT1. With the aluminum chassis, I used this car to win the "C" main in the 2006 Winternats and did not take a bump to the "B"...I was the only non sponsored driver in the top 30 that year in sedan. The Roll-center bridge, shock towers and radio deck had all been made specific to that car to lower the CG and wieght. The car was a lot of work and to undertake the amount of time to modify it was 2 months. It however did handle very well and one thing that I remember was that I had almost no tire wear and everybody was having tire wear issues that year.

Sorry for the long story, but if anybody is considering converting to one, rember that your current setup won't work and you will have to change your setup mechanicly to lower CG and roll center. I'm just suprized to see that a mainline mfg is making them now.

Dude, thanks

I think i will try it out just for the fun since I spend a lot of energy to make the car as light as possible.

I know shocks should be configured for lower weight, but how about the diffs, stock mine are with very thick oil, how thin should it be if just for an examble the car weighs in at 1500 grams?

What you are going to find is that thicker diff fluid or even a spool in the front is going to help more than thinner oil.

HK was release carbon graphite for NT-1 ,
it's from HK Top driver release ,
his point is lower CG & LW, cool down is from air in your body window hole .
but life is shorter than Alum. , fit for not have more bump driver in race .

I can send you "my" MTX4 chassis if James doesn't have any. I still have mine.
