Aerobat I "Bat 1" was a tail-dragger with widely spaced retractable landing gear that folded outward into the bottom of the wing. Most of the aircraft is a reverse-delta wing planform, but the forward fuselage contained the engine which extended in front of the wing. It has two bubble canopies and a lower small window for the pilot to see the ground. There was a single vertical tail with the stabilizer mounted at the top, and small teardrop-shaped tip plates on the tips of the stabilizer.
Aerobat II and III, a.k.a. "Aerobat B", were redesigned and rebuilds of the original. Aerobat II retained the original license. Aerobat III had a tail-mounted pusher engine and was issued FAA number NX64638.
