Last weekend, PopSci traveled to Lakeland, Florida, to watch Mike Selby's 5.5-to-1 scale model A-10 Warthog—star of our recent feature story— compete in Top Gun, an invitation-only event that is effectively the world championship of experimental radio-controlled aircraft.

Selby's team includes pilot Raymond Johns, an Air Force test pilot and three-star general; pit crew/logistician Bill Davidson, who is the Administrative Assistant to the Secretary of the US Air Force; and Bangkok jet-engine builder Pornchai "Hard Porn" Saechour.
