World’s fastest RC aircraft hits a stunning 548 mph – without a motor

Spencer Lisenby with the massive DSKinetic 130-inch Transonic DP RC glider

No props, no jets, no rockets – California’s Spencer Lisenby just broke the world speed record for remote controlled aircraft, taking an unpowered RC glider transonic at 548 mph (882 km/h) using nothing but the wind. Well, that and an incredible degree of skill in a highly dangerous technique called dynamic soaring. And while it’s more or less an extreme hobby at the moment, he’s got some very interesting plans for the technique and the technology behind it.

Active Aero For A Radio Control Car

Posted on by

Motorsport became obsessed with aerodynamics in the middle of the 20th century. Moving on from simple streamlined shapes, designers aimed to generate downforce with wing elements in order to get more grip between the tyres and the track. This culminated in the development of active aero, where wing elements are …read more

Dynamic Soaring: 545 MPH RC Planes Have No Motor

Posted on by

The fastest remote-controlled airplane flight ever recorded took place in 2018, with a top speed of 545 miles/hour. That’s 877 km/h, or Mach 0.77!

What was the limiting factor, preventing the pilot-and-designer Spencer Lisenby’s plane from going any faster? The airstream over parts of the wing hitting the sound barrier, …read more

How To Get Into Cars: Aero Mods For More Grip

Posted on by

In 1960, Enzo Ferrari said “Aerodynamics are for people who can’t build engines”. It’s a quote that’s been proven laughably wrong in decades since. Aerodynamics are a key consideration for anyone serious about performance in almost any branch of motorsport. Today, we’ll take a look at how aero influences the …read more

Gordon Murray is building the T.50, "the purest, lightest, most driver-focused supercar ever"

Posted on by

The man behind the magnificent McLaren F1 is starting up a new company to produce something even more lightweight and extreme than his most famous creation. The 980-kg Gordon Murray Motors T.50 will begin deliveries in 2020 at a price around … Continue reading Gordon Murray is building the T.50, "the purest, lightest, most driver-focused supercar ever"→

Make Physics Fun with a Trebuchet

Posted on by

What goes up must come down. And what goes way, way up can come down way, way too fast to survive the sudden stop. That’s why [Tom Stanton] built an altitude recording projectile into an oversized golf ball with parachute-controlled descent. Oh, and there’s a trebuchet too.

That’s a lot …read more

MCAS and the 737: When Small Changes have Huge Consequences

Posted on by

When the first 737 MAX entered service in May of 2017, it was considered a major milestone for Boeing. For nearly a decade, the aerospace giant had been working on a more fuel efficient iteration of the classic 737 that first took to the skies in 1967. Powered by cutting-edge …read more

Scratch-Built Ornithopter: Here’s How I Flapped My Way to Flight

Posted on by

One of humankind’s dreams has always been to fly like a bird. For a hacker, an achievable step along the path to that dream is to make an ornithopter — a machine which flies by flapping its wings. An RC controlled one would be wonderful, controlled flight is what everyone wants. Building a flying machine from scratch is a big enough challenge, and a better jumping-off point is to make a rubber band driven one first.

I experimented with designs which are available on the internet, to learn as much as possible, but I started from scratch in terms of …read more
