I built a tricopter!

Thanks, Kanga for the links, but I think that this will not work. I have there 6mm solid CF rod, proper strong RC carbon, not one of them from kites, and that tinny bit of twisting flex is too much. These torque tube rods are only 3-4mm. I have to look for 6mm aluminium. I think I will try another thing: I found a carbon rod with aprox 10mm dia and 5mm hole. So I will bore the hole to 6mm and with epoxy slide it on my existing rod. In that case I will have a 10mm solid CF rod between the bearings and only short bits by 6mm sticking out each end- one with motor plate and another for servo arm. That I think should get rid of the twisting. If 10mm solid CF rod will not resolve my problem, than my super druper fancy yaw  system will be good only for proping my wife`s tomatoes 

Trumpy, now I`m looking for aluminium tube or rod, it might work, just have to wait to find out I`ve spent so much time and effort into the looks of my V2, especially on that torque tube, that it would be a shame, if it will not work Now ME=GUINNESS=FEEL BETTER

Well, lads, I f*****up My fancy torque tube yaw system is not working. CF rod has a tinny bit of flexibility and at more than 50% throttle, tail starts to shake, because gyro is trying to compensate. If I decrease gyro gain to stop tail shaking, it has no use any more. There`s no way I can get rid off CF rod flexibility and metal rod is not a option either, I just have to go to old good "servo at the back" system. At least now I can tell about this to the others, my lesson learned hard, dissapointed way

Like I told you: There is no such thing as overkill in RC. :)
As with cars. Good thing too, or there would not be any cars other than Mazda 323 or Ford Pinto. Anything else is just overkill, when you boil it down to what you really need.

It looks extremely proffessional Robo.Almost overkill, but there is no such thing in RC, right?
I like the idea of using boom fin holders to hold your arms to the base plate. I used a similar concept for my tricopter with round CF booms, and when I crash, the boom holders break. Nothing else. I just get some new boom holders for no money at all, and I'm up and running again in 10 minutes.

On a somewhat related note: I crashed my Tricopter pretty bad yesterday. One of the propellers lost a blade! It just went "foof" in mid-air, which made the tricopter turn inverted and then plummet to the ground. Worst crash yet...
Lost some of my plastic boom fasteners, but at ~$0.50 each I have many spares. I just need to exchange them and install two new blades, then I'll be up again.
But actually I'm not going to to that. Instead I have started building a hexacopter and will re-use all the electrics from the tri. I'll keep you posted when it's done. :)
