Default carbon fibre tail rotor?

Is anyone currently thinking of making after market carbon fibre tail rotors (put me on your list)i noticed on alexanders home page that he mentioned the weight saving of the c/f blade reduced enertia to the point of better control of the back end,i have made a few prototypes out of venetian blind aluminum strenghtened at the root to stop flexing and was impressed with half the weight of the original but left it on the table (before i read alexanders page)thinking it was to light and took more energy (i was only thinking of better flight times at the time)to pull it around as it didnt have the mass to keep it turning but obviously i was heading down the wrong track with that theory because the lighter the blade the quicker it will stop and start hence the better control.

Hey, Will! Carbon fiber sounds good, but I had a thought. Has anyone tried cutting the tail rotor down like we do the main blades. It will reduce the pitch requiring a Piccoboard adjustment, but it will also lighten the tail and allow the little tail motor to run with less resistence. I have been thinking about this for awhile but don't have a spare tail rotor to try it on. I did some calcs and determined that 1mm at the tip and 2mm at the root would be a good start for testing. Tell me if I'm off base here. Thx, Eric S.

Makes sense but do you think the extra speed required to make up for the cut tips would nulify the resistance saving(i think it would ,resistance is resistance)1mmx2mm sounds like a good start(is that based on a percentage of square area of the main blade?).

Yep, it is. Like I said it was just a thought. Carbon will probably be the best bet. I think that rotational mass is what we are more concerned with, right. Thx, Eric S.

Hi friends,

I'm molding CFK blades (with success ... and sometimes ... problems) at the moment, but a future project is to mold the tail rotor.
I'll get you informed when it'll be the hour.
