Texas Tried and Texas True Windmills We are a group of windmill enthusiasts that bring windmills to you at discount prices. We offer factory direct windmills, at low cost, that are fashioned after your grandfather’s 1930’s Aermotor Windmill. No aluminum, no plastic, only “no worry windmills” are sold here. Anything less than a true windmill will not selfcontrol the speed, or automatically furl (turn) out of the wind at high speed.
