What fuel is best for your engine?
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 […]
Ivan Pettigrew: the Sage of Chilliwack
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 […]
Big Scale Made Easy!
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 […]
Improve Your Hovering
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, […]
Hot move: negative snap from inverted climb
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 […]
Museum Scale H-34
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 […]

3D Flight Checks
A series of flight checks are required to program your radio for 3D flying. These flights should not be viewed as practice flights, but a time to evaluate your plane’s tendencies and fine-tune your radio setup. It’s therefore important to conduct your initial flight checks in calm conditions to make it easier to detect your […]
The ProTek R/C True Glow
With the ProTek R/C ”TruGlow” Remote Glow Igniter System you can leave your old glow plug battery in the field box because the “TruGlow” uses your receiver battery to power the glow plug in your airplane or helicopter. This not only makes it easier to start your engine, but can also be setup to help […]
The ProTek RC Transmitter Case
Everybody loves getting a new radio system, but unfortunately that could also mean the additional cost of a new radio case to protect that fancy new radio. Enter the ProTek R/C Universal Radio Case where the minds behind ProTek R/C have developed an all in one solution that will allow you to use a single radio case […]
O.S. GT15HZ: New Gas Engine
Many years ago we tried using Zenoah gas engines in our helicopters, but there were several problems we could not overcome. First, they were not designed to be used in helicopters. Rather, they were designed for some type of commercial operation, such as powering a small blower. This meant they were unbalanced, so they had […]
