First 6 K.W one.
Blade hub fractured. Blades Capput. Landed fields away.

Top mounted rotation gear box failed. Blades came off again.

Top mounted power slip ring system failed.

Modified it to rotate at ground level. Power slip ring system done away with. Still working.

Various other little ones failed / Never produced Any Power.
A Gentlemen that lives in the same Village wants to have a go at one.
Any suggestions on one that works. Produces power. Is reliable.
Many thanks.
