The original Christen Eagle was a homebuilt "hot rod", but this RC version offers the original's aerobatic performance with Great Planes assembly ease! You start with a prebuilt wood airframe. The trademark "Eagle" trim scheme is already applied, done in strong, long-lasting MonoKote® colors. Prehinged ailerons, painted fiberglass parts and 1-piece wings help cut assembly time — and so do the unique interplane struts. They not only do away with brackets, hardware and hassle; they install without tools, making them easy to attach and remove. The Christen Eagle is versatile, too, and a great performer with an O.S. 55AX 2-stroke, 72FS-a 4-stroke or an ElectriFly® RimFire™ .55 outrunner.
