LOL...yes well I do have a reputation around here as a wild man I'm still going to figure out a way to do loops and rolls with my cx2. Mind you I'll probably end up spending more than the things worth to make it brushless etc. but I will get it done

Keep us posted on the titanium. I was talking with my uncle the other night who used to be a metallurgist. He said titanium would most likely be our best bet for some of the very reasons you mentioned above. Lightweight, super strong, and will take some pretty big impacts without bending or breaking. Your barking up the right tree Gary. The CF idea for the outer shaft is great. Personally I would like to see a slightly smaller outer shaft with a CF outer tube that covers it....alot like Solo's flybar mod that I currently run. You know the caliber of ditches I have and since modding the flybar with the CF tubes I can honestly tell you I haven't bent a flybar. So with that thought if we were to machine a smaller outer shaft then sleeve it with CF we should be able to achieve the same result. Only problem I can see is what impact is the swash bearing going to have running on the CF outer, second what kind of force is the mounting screws on the outer hub going to have on the cf in a hard blade strike. Then again if you look at the tailboom I have the rear fins pass through the cf tube with a steel rod. I have had some wicked strikes on it and zero effect on the boom. My thinking is that the small holes for mounting the lower hub would be a weak spot, a lateral shift on the CF might me enough to fracture it causing cracking, then stress fracturing up and down the length of the shaft. Just a thought though!
