Lukey made me this nifty blower for my Tucano.

It uses a 3" bilge blower and a 7ah gell cell battery. The blower "moves" air instead of "blowing" like a leaf blower would so it sets up a breeze that spins the turbine at about 1500 RPM. It's nice to have on the Turbo Prop because it takes longer to cool off because of the gear box. I don't have to kill the ECU battery anymore with the cool down cycle...I just park the plane, shut it off and hook up the blower.
