RC Airplane Builds

Watched a video and want to build it? Every project lives here with the parts that don't fit in a video — dimensions, electronics, a parts list, and the honest story of what worked and what didn't. Start with a copy-exact build, learn from an experiment, or grab a guide — the free foam-board plans are all here too.

Want true-1:1 templates instead of measuring? The 30″ ER Sparrow Mk II plan set prints at exact size — tiled for home printers or one 36×48 sheet. $8, free revisions for life — or $29.99 laser-cut as a kit.

Build Your First RC Airplane

BeginnerBuild time: ~2 hours

The complete beginner guide, built on my most-watched plane: a 30″ foam-board plane with the full plans, exact shopping list, wiring, CG, control throws, transmitter setup, preflight, and first-flight guide — everything in one page.

✈ Buildable Planes

Every airplane from the channel. Each card says whether it has plans, enough dimensions to build from the write-up, or was a one-off experiment with no plans.

The 20-Foot Cargo Plane — a six-part series

One plane, documented start to finish: the 10-footer that taught the lessons, the week of design and material tests, and the build itself — running now, aiming at Flite Fest's 55-pound combat limit.

The 10-Foot Combat Plane Built in an RV

AdvancedBuild time: 3 days

Three days, hardware-store foam, a golf-cart launch in front of thousands — and the three lessons that shape this year's builds.

Proving a 20-Foot Cargo Plane

AdvancedBuild time: ~1 week

Before cutting a monster: a foam-cored box spar, pink insulation foam, three glues tested, and a prototype that actually glides.

Building the 20-Foot Plane Became a Nightmare

Advanced

Wing spars ripped from 2x4s that snapped on knots, a fuselage an inch longer than the truck, a workbench that bowed the airplane, and foam board half an inch short — three days from a pile of lumber to a shape.

20-Foot Plane: Too Heavy for Combat?

Advanced

Finished elevators, a tail that comes apart, 27 laser-cut ribs, aluminum wing joiners, a quick-release nose — and a weight estimate creeping toward the 55-pound limit.

Four Days to Finish a 20-Foot Airplane

Advanced

The first wing Eric ever skinned, laser-cut motor pods bolted through a finished skin, outer wings that didn’t fit the center section, 52.6 pounds against the 55-pound limit — and an unfinished plane loaded into the truck.

The 20-Foot Plane at Flite Fest: It Flew. Then It Didn't.

Advanced

Three days finishing it on site, a CG that was nowhere, landing gear rebuilt overnight by aerospace engineers, a maiden in heavy wind, a crash — and the two-motor wing from the wreck that fought in the last combat.
