-
- Dan welding the frame
-
- laying the magnets out on the disk. 16 magnets 75x50mm
-
- resin casting day. there is no lid on the magnets
-
- Hugh explaining stuff
-
- interesting tail stops

Hello
Mr. Hugh Piggott
thank you for the photos, always they are a contribution to increase the knowledge on the wind turbines.
Thank you in his time
Question
Which is the power that delivers the turbine of 3 meters?
An embrace
hi Alex,
The new 3F turbine is designed to produce 800 watts, the same as the recipe 3000 turbine.
best wishes, Hugh
