ABCs of Ball Links

ABCs of Ball Links

Improvements in RC helicopter design and performance have resulted in the almost universal use of the ball link in all modern helicopter control systems. Most major manufacturers make their own ball links to their specifications, with their name, logo or other such mark on the body of the link. Although these links are slightly different, […]

New development in VTOL design

New development in VTOL design

Combining the hovering capability of a helicopter with the high-speed, long-range flight capabilities of a fixed-wing aircraft has intrigued engineers for decades. The Australian company StopRotor Technology has a new approach: their Hybrid RotorWing design concept has a main rotor that switches from fixed rotor to fixed wing in mid air. According to Gizmag’s Jan Bellezina, “The Hybrid […]

Historical Perspective of the RC Jet World

Historical Perspective of the RC Jet World

 On my recent assignment to cover the 30th Annual Southwest Jet Rally for MAN, I took the opportunity to ask Mike Kulczyk, a good friend and certainly one of the pioneers in jet modeling, to give me his assessment of the evolution of R/C jets. Over the 30 plus years that I’ve known Mike, I […]

Must-Know Fuel Facts

In today’s hobby industry, commercial fuel-blending companies are hard-pressed to make a profit, and stay in business. Nitromethane is no longer made in America; our only refinery dedicated to its production has been moved to India. We now import nitro from China and are subject to interruptions in supply, as demonstrated when refineries shut down to […]
