AH-56 Cheyenne Project – Part 5 – Tail Controls

Jan 30, 2015 No Comments by

This installment continues construction of my 700-size AH-56 Cheyenne.  The project begins here. Since the Cheyenne’s tail rotor is mounted at the end of a long extension shaft, I needed to fabricate a control linkage with a bellcrank,.  I’ve just gotten into having parts 3D printed by Shapeways.com, and this was a perfect application for their [...]

Jan 22, 2015 No Comments by

This installment continues construction of my 700-size AH-56 Cheyenne.  The project begins here. With the Cheyenne’s powertrain and cyclic control issues resolved, next step for the project was completing the tail boom.  As noted previously, I’m stretching a Blade 600 X to 700 size, so I needed to fit a longer tail boom and torque [...]

AH-56 Cheyenne Project – Part 2 – Mechanics

Jan 21, 2015 6 Comments by

BUILDING THE MECHANICS: As noted in my intro posting, my first priority for my 700-size Cheyenne project was to build and test fly the mechanics. After all, if I couldn’t get the outrigger tail and variable-pitch pusher prop to work properly, what was the point? First decision was choosing the basic mechanics. Although this is [...]

Lockheed AH-56 Cheyenne Project

Jan 20, 2015 5 Comments by

A few years back I designed a scale model of the Lockheed AH-56 Cheyenne, probably my favorite helicopter of all time.  The experimental Cheyenne featured a variable-pitch pusher prop and small wings, which allowed it to fly much like an airplane and gave it a top speed of nearly 250 MPH.  My Cheyenne was based [...]

Torque-Tube Tail Upgrade

For several years, Align’s T-Rex 450 series has dominated the small helicopter market. Rather than resting on a proven design with excellent quality and fit, Align has gradually upgraded the heli to keep up with (or ahead of) their competitors, imitators, and outright copiers. With the release of the T-Rex 450 Pro, Align raised the [...]

May 13, 2014 No Comments

Over the last couple of years, Blade RC, long a major presence in mini and micro helicopters, has released a series of larger helis ranging up to 550 class. With the Blade 600X they have raised the ante with a competition-grade 12-cell flybarless 600, and I couldn’t wait to build one. The Blade 600X Pro [...]
