LEGO Technic Windmill: Which Blade Mills Chips Best?

Will the classic, solid, or wind-farm style generate more power? 00:00 Building the Windmill 00:42 Classic Blades Test 01:00 Solid Blades Test 01:33 Wind-Farm Blades Test #legotechnic #customlego #legoideas #legotutorial #legomoc #legobuild #mechanical #afol
