Although highly popular with the giant-scale crowd, our 1/3-Scale Spacewalker is simply too big for some modelers to haul around. In response to all of you who asked for a smaller version, we bring you the1/4-Scale Spacewalker II.
Legal for IMAA and QSAA fly-ins, this is an exact 1/4-scale model with the heart of a sport model.

It's made for flying! The thick semi-symetrical airfoil and long tail moment provide perfect stability and low speed handling. At full-throttle, it will do all the aerobatics you ever dreamed of.
