EPP Handlaunch Glider ~Made in the USA~ Out of Stock |
 The Alula is a
compact, lightweight, and durable R/C handlaunch glider that was designed for
light lift conditions and tight flying spaces.Don't be fooled by its looks; the Alula is in reality a very functional design that benefits from each of its unique design features. The Alula was designed specifically with the SAL (Side-Arm-Launch) in mind. The swept forward planform eliminates tip stalling, which allows you to core small, near-ground thermals. The swept forward wing planform also places the launch point closer to being in-line with the CG, making sidearm launches straighter and higher. The sweep forward combined with a large fin, reduces the tendency of the glider to yaw during a SAL, and thus launch heights of 50-60 feet (15 meters +) can be achieved. What's with the name, Alula? Well, an alula, according to Webster's Dictionary, is "the bastard wing of a bird". It refers to the thumb feathers on the leading edge of a bird's wing that help to delay the onset of a stall by maintaining airflow attachment at high angles of attack. We thought this name was fitting, given the low speed performance of this little glider and its bird-like appearance. Afterall, its wing design was inspired by the real thing.  Specifications:Wingspan: 34 in (860mm) Wing area: 234 sq.in (15.29 sq.dm) Weight range: 4.2-4.6 oz (120-127gm) Skill level: Intermediate to expert Kit building time: 8 - 12 hours Radio requirements: elevon mixing with dual rates and/or ATV (Adjustable Throw Volume), sub-micro radio components (see below for details).

*Special note on radio equipment - PLEASE READ In order for the Alula to maintain the flight characteristics described above, sub-micro size radio equipment is required to keep the weight down. The Alula is a very pitch sensitive aircraft and therefore requires dual rates or ATV (Adjustable Throw Volume) on at least the elevator channel (channel #2 in most cases). You will need to have the capability to reduce the throw percentages down to 20%. Most computer radios have this function. Unfortunately, the inexpensive 2 and 3 channel radios with just v-tail mixing do not have these sensitivity adjustments, making it difficult to fly this glider with them. So please invest in a radio with dual rates and/or ATVs. |
