The original forward-swept “fly anywhere” R/C glider! This organic design is a light and buoyant flier. The unique and refined bird-inspired wing design facilitates the sidearm launch method and maintains maneuverability, even at very low airspeeds. New molded ARCEL foam airframe provides a stiff and lightweight structure and makes assembly a snap. This “urban glider” can soar in the most unconventional of locations. No high-starts, motors, or spinning propellors required… just fling and fly.
- 2x sub-Micro Servos
- 4.8v 300mah 1/3AA size Nimh flat pack
New Kit Features:
- Durable, quality molded ARCEL™ foam airframe manufactured in the USA! Ensures fast, consistent, and easy assembly. No covering material required. What is ARCELL foam and why did we use it instead of EPP? Read below.
- Thermo-formed belly skid for landing protection.
- Quick-assembly kit can be built in one evening with little glue. Say goodbye to the taping blues!
- Modular airframe can be built as one piece for maximum durability or collapsible with our original magnet lock system for easy travel and storage.
- Integrally molded control surfaces for minimum weight and building ease.
- New wing design with fully encapsulated carbon-fiber joiner rod and easy-install carbon-fiber wing spars.
- Further refined design
- Complete hardware package includes ultra-light linkages, carbon-fiber pushrods, decals, and more!
- Detailed construction manual (of course, if you’ve built a few of these, you may not even need it!)
What is it? ARCEL™ foam is a blend of polyethylene and polystyrene foam. The polyethylene provides toughness and the polystyrene adds a greater amount of rigidity and stability than that of EPP (for a given density).
ARCEL is not brittle like pure polystyrene and will not flake off. While ARCEL may not have the same “bounce” quality and dent resistance of EPP, its superior stiffness and stability allow us to achieve a delicate and refined “no covering required” design that is ultralight, yet rigid and stable enough to withstand many sidearm launches.
Why? While we think there is no substitute for EPP in “rough and tumble” type gliders that see alot of abuse on the slope (like the Weasel), ARCEL made more sense for the Alula given the glider’s thin wing and low weight design requirements. A few other benefits of using ARCEL are its paintability and sandability, which allows one to sand away the small surface vent marks resulting from the molding process (for cleaner looking and more aerodynamic surfaces).
