No, Shufflez,

I was agreeing with You, sorry.

I think a hollow core outer shaft would work just fine in c.f.; I was talking about the inner being made of c.f., I don't think that would 'fly'

But, Yea, one could experiment; that's the fun of it.

I THINK A TITANIUM OUTER SHAFT TUBE WITH A TIGHT FITTING C.F. SLEEVE WOULD BE THE ULTIMATE ! !

It would have to be perfect dimensions when You're through; thickness isn't too much of a factor, as the inner shaft is so skinny.

So far so good; the shaft works great! It fit perfect in the heli; I've had 4 bad ones messing around; broke a stock skid; bent the stock flybar, but the inner shaft held true.

This is getting exciting!
