r/c side-arm-launch glider |
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. We call this our "urban
glider", due to its ability to soar in the most unconventional of locations. No
high-starts, motors, or spinning propellors required... just fling and fly. Its
as close to an R/C boomerang as it gets!

 Three
Piece Wing Add-on Kit for Alula (read below for more info)
Price: $7.50
Add-on kit allows for easy removal
of wing panels for travel and storage. Includes magnets, aluminum couplers, and
hex key. Adds 8 grams (0.25Oz) weight to basic design, but ensures secure
attachment of removeable wing panels during launch. We recommend this option to
die-hard travelers only. For minimum weight and best light air performance, the
basic kit is best. |

 What is ARCEL™ foam and why did we use it for the Alula
instead of EPP (expanded polyproylene)?
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). |
