Radio Controlled Scale Bell-Boeing V-22 Osprey Model

Radio Controlled Bell-Boeing V-22 Osprey - RF Cafe Video for EngineersAs with amateur radio hobbyists who continually help advance the state of the art in electronics, software, and communications, so too do model aircraft hobbyists help push back the frontiers of ignorance in their realm. Guys like Tom Mast, a Staff Engineer with Bell Helicopter Textron, are part of a fairly elite cadre of people with an ability to integrate a large collection of skills into a single sophisticated project. Knowledge of rotorcraft and fixed wing aerodynamics, propulsion system mechanical and electrical requirements, microcontroller programming, structure weight-strength tradeoffs, materials science, design-for-production aspects, and the skill to fly both fixed and rotor wing models were necessary to pull this off. I have not found any detailed history on the development, but about three years of dedicated effort was required from concept to reality. As you can see from the detailed photos in the build process documentation, the high quality of engineering throughout is typical of what you would find on a military-grade system.

The radio system is a highly configurable, 2.4 GHz, spread spectrum model that is in common use by fliers of top-end helicopters and aerobatic airplanes. When I opened up my 2.4 GHz DSSS radio a few years ago and documented it, I found off-the-shelf ICs and RF components. The magic is in the controlling firmware/software.

Kits are available from Tom's Rotormast company both for a basic, profile fuselage version and for a full-scale fiberglass body. It is a bit pricey, but it does include specialty components like high torque servos for nacelle tilt actuation (no 5,000 psi pneumatic pistons like on the full-size version), wiring harness, and microcontroller. You will need to provide the RC system, motors, batteries, gyros, and Electronic speed controls (ECSs). Total investment will be somewhere in the $3k range. If you have a much more limited budget but really want an R/C V-22 Osprey, try this one on for size for about $130.
