After nearly 6 months of building, I have finally completed my Allegro-Lite sailplane! I started at the beginning of November last year, and just this week finished it up. It’s a great feeling to finally get something like this done, and just in time for soaring season! To celebrate, I have started cleaning up my shop downstairs to make way for the ship I’m going to use for the Louisville Area Soaring Society’s Speed 400 F5J Electric Sailplane Competition coming up in August.

Anyway, back to the Allegro-Lite — it’s a really cool plane, from a completely nerdy point of view. You see — most “competitive” (meaning “efficient”) model sailplanes these days are really expensive — they involve things like hi-load foam, Kevlar, carbon-fiber, and generally a lot of expensive composite materials. Those materials can make things really strong, and yet really light — which is something you need for a really efficient wing on a plane. Well — the Allegro-Lite is an exception because A) it’s made from wood with some carbon fiber (not terribly expensive, B) it is really light and C) despite the previous two things, it is REALLY strong! The design is completely free to the public (courtesy of Dr. Mark Drela from MIT), and there are plenty of other Drela-devotees around to offer help, and in the case of the Allegro-Lite, a near-complete walkthrough. I’ve even pitched in myself with a build gallery with annotations.

So, this summer I intend on getting out and flying as much as I can, and competing as often as I can in regional contests. The Allegro-Lite will be along for the tow as well!
