All About Avionics: We Came, We Saw

There are seemingly few more mundane tasks than making holes, but there are as many ways to do them, as there are different sizes and shapes of holes. This month, Stein Bruch describes how to cut holes in the panel yourself, using tools you may already have around the shop.

Columnist Jim Weir comes up with what he thinks is the optimal design for getting power from the 12-volt aircraft battery to the LED without wasting any.

The Home Machinist

Charlie Taylor, the Wright brothers trusted right-hand man and machinist, made their early powered flight experiments possible. And he built the engine using only a drill press, a lathe, a simple scale and more than a little ingenuity; by Bob Fritz.

Wind Tunnel

This month columnist Barnaby Wainfan takes a look at how the airplane responds in roll when the pilot is maneuvering. Two key factors are roll acceleration and the steady-state roll rate.

Van’s RV-12

0
In typical fashion, Van’s Aircraft refused to rest on its laurels after the RV-12’s prototype debut last year, and sought to improve on an already good design. The new production airplane has changed (beyond its color), with a castering nosewheel, toe brakes instead of a grip, reshaped control sticks for better clearance, ground-adjustable seats fore and aft as well as in tilt, and the list goes on. Best of all, this day/VFR machine is still a delight to fly; by Ed Kolano.

Lancair ES-P

0
Robert Simon had the distinction of building the first Lancair ES-P to fly. But the process wasn’t without its challenges. The ES-P employs the cabin design and structure of the pressurized, retractable Lancair IV-P, but has a larger wing and fixed gear. During the build, Simon also deviated from the base design with changes that required factory support to accomplish. Not only did he learn much, he ultimately got the plane he needed; by Dave Higdon.

In Case You Missed It

Mind the Gap

An ill-fitting joint where the wing joins the fuselage doesn't leap to mind as a foremost source of induced drag, but the effects can be significant.
