One of the more active booths here at RCX is the Horizon Hobby booth. They have a number of airplane displays and a Horizon Hobby flying cage where they have a continuous flight demos happening all day long.
The Scale Squadron of Southern California is hosting the Battle of the Builders static contest. RCX attendees can vote for their favorite plane … I haven’t put in my ballot yet but it’s going to be a tough decision!
There is a concern throughout the fuel industry that many of the world’s engine manufacturers are too conservative when recommending lubricating oil percentages for their products. A high lubricating oil percentage never hurt an engine … or did it? A growing body of experimental and practical evidence suggests that modern engines are being impaired by […]
Poet William Blake said, “Great things are done when men and mountains meet.” In the misty foothills of Chilliwack, BC, there lives such a man. Humble and unassuming, Ivan Pettigrew has become a legend of the electric RC community and a MAAC Hall of Fame inductee. His spectacular subjects and straightforward design philosophy have spawned […]
Large-scale helis (“large” in this context meaning anything bigger than 450 or 500 size) have a reputation for being expensive, complicated, and nerve-wracking to fly. The goal of this project was to have a scale heli that would be affordable, simple and fun. To fulfill these objectives, I looked for a scale body that would […]
Having the helicopter properly maintained and setup is a vital part to any phase of helicopter flight, and I assume this has already been accomplished. What remains are some of the advanced techniques to use when hovering. But before we get into actual hands-on hovering techniques, I think it’s important to discuss the basic principals, […]
For this maneuver, the pilot enters from inverted flight and pushes to establish a 45-degree climb then he performs 1½ negative snaps. After the snap, another line segment (equal to the first line) is then executed. Once the maneuver is complete, the pilot must pull 135-degrees to exit in inverted straight and level flight. This […]
Darrell Sprayberry of Dalton, GA has earned a reputation as one of the finest scale helicopter modelers in the world, and at this year’s Toledo Weak Signals Expo he placed first in the Helicopter class with his fantastic scratch-built H-34 Choctaw. Also known as the Sikorsky S-58, the H-34 is an iconic design–perhaps the best […]
