Custom RC8T carbon fiber chassis question.

[MetalMan]

How about a hybrid chassis? 7075 up front to take care of that kickup, and 3mm-4mm carbon fiber for the rest of the chassis to keep weight down and rigidity up.

i was thinking the same thing but not sure how to best mount the two pieces together. any suggestions?


a company called matrix concepts does something like this although they still use all CF but i was thinking something along the same lines but with alum for the nose piece.

you can see in their pic of the losi CF chassis that the kickup is a separate piece screwed to the main chassis.

i was talking with Danny from TEkno and he said the MatrixConcepts chassis is actually 3 pieces and that quite a few guys use them at ARC Raceway where he races. he said surprisingly they hold up very well. he said he has seen them come down on the 2nd peak of a double and hit dead center on the chassis, in stead of clearing the jump, and not skip a beat. i would have expected to hear stories of them snapping in two. after he told me this i felt a little more open to trying the CF for a chassis.

also, the piece i am getting would be 5mm 1k weave. it is still lighter than a 3mm alum, or a 4mm milled alum chassis. the 1k weave is a bit stronger than a 3k weave due to finer weave i am told.

anyway, we'll see.

Have you tought about laying up your own carbon fiber plate with the kick up? It's not that hard to do.
