The latest development of small, light weight, powerful brushless motors (ART-2000) made possible to create this super light weight electro-glider. The Castor flying weight is approx. 1000 grams (35oz.) It feature HN1033 airfoil that was specially modified for this sailplane, the benefit of that are very wide speed range and good thermal abilities. The Castor wing also could be built as polyhedral wing if desired by the builder.
Features:
- composite fuselage pod is made of few layers of fiber glass with glass roving and carbon fiber reinforcements for extra strength. It has removable canopy for rapid access to the radio gear. The V-shaped wing saddle with molded in nuts for the wing mounting bolts.
- tapered tail boom is made of carbon fiber/glass composite.
- wing cores are precision cut from white polystyrene foam, and the black poplar veneer is
bonded to the foam with aircraft industry grade epoxy in high pressure molds for perfect airfoil fidelity and a warp-free wing.
- light weight tail made from balsa, has pre-hinged control surfaces.
Kit contains: model components, plans, step by step instructions, and all necessary hardware.​

T-tail version is also available.
