Motor Efficiency: The Missing Piece of the Puzzle

Motor Efficiency: The Missing Piece of the Puzzle

While winding resistance (Rm) is an important consideration in calculating losses, an equally important factor is motor efficiency. Real world efficiencies for electric motors – as measured on a dynamometer – can be all over the map. Some high-quality brushless motors can hit efficiencies in the 90% range, while others may be under 60%. This […]
More Tail Rotor Stabilization

More Tail Rotor Stabilization

How It All Works – This now results in two opposing forces acting on the tail rotor system. The aerodynamic force wants to streamline the blades to zero pitch while the centrifugal force wants to rotate the blades to their maximum pitch. These tail rotor weights produce a centrifugal restoring moment (CRM) because they act […]

Hungary’s 4th Multiplex Easy Wings Cup

After an idea came up late 2008 a small group of Multiplex funs came together in Hungary for a small contest. Rules were simple and clear: same planes (Easy Star, Easy Glider) were allowed to compete in two simple events: time gliding and gate race. The uniformity of the planes assured the contestants having the […]

Pilot Projects: Pitts Special S-1C “Little Stinker” [January]

Pitts Special S-1C “Little Stinker”: Betty Skelton flew the full-scale version (now in the National Air and Space Museum) to victory in the 1949 and 1950 International Feminine Aerobatic Championship.  Herb scratch-built this scale version from plans he found online and writes, “It’s beautiful flyer once it’s in the air, but the short-coupling of the […]
5 Setup Solutions You Need to Know

5 Setup Solutions You Need to Know

After installing your servos according the manufacturer’s directions, you might find that when the servo arm is placed on the spline, it isn’t at a perfect right angle to the servo casing. Or, after you’ve hooked up the various linkages, you discover there is too much or not enough travel throw when a certain control […]

Heli-Max AXE 100CP Helicopter

Heli-Max AXE 100CP Helicopter

The Axe 100 CP is one of the most innovative helis available. A flybarless, collective pitch head gives it a wide performance range with a low parts count, making it more efficient and more durable than a flybar design. Digital servos are used for speed and precision, with a full case design for damage and […]
