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. $9, free revisions for life.
See the plan set →Planes you can copy — each has dimensions, electronics, and a parts list.
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 crashes, dead ends, and one-off experiments. The most useful pages I've made — every fix started as a failure.
Honest takes on gear and planes I've actually flown.
Not RC planes — printer conversions, rocketry, smart-home hacks, and gear reviews from the same workshop.
A spring-steel conveyor bed, re-tuned e-steps and OctoPrint turn a normal printer into one that prints parts longer than the machine.
Backyard engineeringA Wemos ESP8266 swings a vent open and closed, a DHT22 reads the room, and Alexa runs it by voice — plane servo skills, aimed at the house.
Rocketry · SafetyAn honest, no-recipe look back at homemade rocket motors — why they're riskier and more regulated than YouTube suggests.
Technique · FabricationRoll strong custom tubes from paper and thinned Titebond III — great for tail booms and wing tube sleeves too.
Review · FPV / CameraThe FPV drone and 360 camera combo through an RC builder's eyes — what it's great at, and where it isn't worth the money.
Don't copy my planes — beat them. The Airplane Designer turns your wingspan and flying style into a complete design: CG, wing loading, thrust plan, and a buyable parts list.
