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.

Super simple foam board RC airplane for beginners

Build Your First RC Airplane

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.

Copy-Exact Builds

✈ Buildable Planes

Planes you can copy — each has dimensions, electronics, and a parts list.

Learn From My Mistakes

Experiments & Failures

The crashes, dead ends, and one-off experiments. The most useful pages I've made — every fix started as a failure.

The 10-Foot Combat Plane Built in an RV

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

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

A 3D-printed RC plane that finally flew after a wing failure
Redemption · 3D printing

I Almost Gave Up on My 3D-Printed Plane

Five months, one folded wing, and the three fixes that finally got it flying: a carbon spar, a forward CG, and the speed a printed plane needs.

RC plane wing that folded in mid-flight, examined afterward
Post-mortem · Structures

The Wing That Folded in the Air

A mid-flight wing failure, taken apart: where a wing folds, why it folds there, and the spar lesson behind it.

Homemade foam board flying wing that finally flew after five attempts
Debugging · Flying wing

Five Failed Flights, One Root Cause

A flying wing that wouldn't fly, and I nearly quit. The CG rabbit hole, a dead ESC, and the under-cambered trailing edge that was the real culprit.

A Scratch-Built RC Hovercraft

No plans, just a challenge: how a hovercraft floats on a cushion of air, the skirt-hole problem rocky ground kept exposing, and the running gear behind it.

Turning a CR-10 into a Belt Printer

A spring-steel conveyor bed, re-tuned e-steps and OctoPrint turn a normal printer into one that prints parts longer than the machine — unattended.

A DIY Alexa Smart Vent

Same servo and wiring skills as a plane, aimed at the house: a Wemos ESP8266 swings a vent open and closed, a DHT22 reads the room, and Alexa runs it by voice.

My DIY Rocket-Engine Experiment

An honest, no-recipe look back at homemade rocket motors — why they're riskier and more regulated than YouTube suggests, and the safe, legal way into rocketry.
