Bringing UAV Technology to the Backcountry
If you want to fly over the most rugged terrain in the West, you don't build with 80-year-old technology. You look at what’s currently dominating the skies: High-Performance Composites.
Military-Grade DNA: Today’s 20-minute build video shows the full lamination of the Canyon Lightning™ wing spars. I'm using the same "Unitized Exoskeleton" logic found in tactical military drones. By wrapping a lightweight Douglas Fir/Foam core in Hexcel® IM2 Intermediate Modulus Carbon, I'm creating a "Black Gold" backbone that has no equal in the Part 103 world.
Weight vs. Strength:
Legacy Aluminum/Wood: Usually weighs 40–50 lbs and is rated for a 4G "limit" load.
Canyon Carbon-Hybrid: The Canyon Lightning™ complete wing set is tracking for under 24 lbs per side with a 6G "Ultimate" safety margin.
Why this method wins:
Most ultralights are held together by thousands of rivets and bolts, each one a potential failure point. The Canyon Lightning™ spars are unitized. The carbon isn't just "on" the wood; it is the wood. This eliminates "mechanical play" and "hole ovaling" forever. It's time to prove that a "normal guy" in a garage can out-engineer the big manufacturers by using smarter physics and better fiber.
