[RE-wrenches] Stuck in a furl

[Dan Fink]

The furl bearing and yaw bearing are common failure points with these
turbines after years in the air. We have also observed there is no way to
align replacements. We could have put in  Delrin  bushings for a few months
more life, but we ended up building him a new turbine, a Hugh Piggott
design and a new custom controller to replace the EZ-Fire controller....we
could have re-used the EZ-Wire but simply didn't trust it, the new one is
incredibly versatile, programmable and has communications capability.

Contact me off list for more information about the controller or turbine.
