Hmm, and I could change the size of the vane to change the point at which it furls...

zing;

Might I suggest that you build one to spec first. Then experiment on that working unit.

Unless you are either very good mechanically or just like to play. First attempts often fail when new folks decide to "improve" the design before they truly understand it.

If it is simply for the experience have fun but if a working turbine is the goal build to plan and go from there. A LOT of thought and hands on experience has led to this design and it would seem silly to just start tossing changes at it until you understand why it is the way it is.

Just thoughts that might save you [and others] some resources.

I wholeheartedly agree. I fully intend to build an Otherpower 10' pretty much exactly to spec before I do this. I don't even have to change the design for what I'd like to do with the bevel gears and shafting -- it would just simplify it significantly. Now that I've read the responses, I understand the way the furling system works better -- I was having trouble visualizing the forces involved and the replies to my post were enlightening. I think it may end up being simpler for me to build a machine with the same physical arrangement of rotor, tail, and yaw axis than to reinvent the wheel in trying to eliminate one pair of bevel gears. Thanks, everyone!

Yes. It may work like the offset alternator, there may be a minimum vane size below which it will work so I wouldn't go for a vane that is too small. Better to do most of the adjustment on the main tail weight and pivot angle.
