Although it looks like it’s straight out of the 1930’s, don’t bother looking up this one in your aviation history books. The Spacewalker was designed by Jesse Anglin of Hendersonville, North Carolina and first flew in 1986! Despite the fact it is a relatively new design, the Spacewalker manages to capture all the spirit of Aviation’s Golden Era.
SIG brings you the Spacewalker in 1/3 scale. Every effort has been made to retain the scale features of this charming homebuilt. Plans for the full-size aircraft were scaled down for the ultimate in accuracy. Construction is easy with pre-formed fiberglass parts and SIG’s famous photo-illustrated assembly manual.
In the air, it is certain to please. Designed from the start to handle any kind of sport aerobatics, it has proven to be one of our most exciting models to fly. The big wing, thick airfoil, and long tail moment all make for stable approaches and soft, slow landings. But before coming back to Earth, it will do enough loops, rolls, snaps, and spins to make any sport pilot happy.
