Lockheed AH-56 Cheyenne Project — Scratch building a scale hybrid Heli

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 […]
The 65" long fuselage was drawn in Rhino 3D to verify fit for the internal mechanics.

AH-56 Cheyenne Project – Part 5 – CNC Machined Plug

This installment continues construction of my 700-size AH-56 Cheyenne, which began here. After a break to pursue some other projects, I’m back to work on the 700 size Cheyenne.  The next step was making the plug which I’d use to lay up the female mold for the fiberglass fuselage.  As noted in the first installment of […]

AH-56 Cheyenne Project – Part 5 – Tail Controls

AH-56 Cheyenne Project – Part 5 – Tail Controls

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 […]
The two tail servos were mounted in a tray milled from 2mm carbon fiber.

AH-56 Cheyenne Project – Part 4 – Tail Boom

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 3 – Powertrain and Cyclic Servos

Here we continue my Cheyenne scale heli project, introduced here.  The construction of the complex tail unit was covered here.   MAIN GEAR AND CYCLIC SERVOS: While I had good reasons to choose the Blade 600 X for my mechanics, there was one feature of this particular heli that cost me some extra work. You […]
The Cheyenne's most notable feature was the variable-pitch pusher prop.  This and the small wings allowed the AH-56 to fly much like an airplane, hitting speeds up to 250MPH.

AH-56 Cheyenne Project – Part 2 – Mechanics

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 […]
De Havilland DH 88 Comet Full Build Part II

De Havilland DH 88 Comet Full Build Part II

 Building a wing: The plans for this model were hand drawn by Ivan Pettigrew. A well know and respected designer. They were somewhat rough in nature but did allow for very easy modifications. All the drawings were on  a single sheet so it was necessary to cut each section from the main plan sheet in order to simplify […]
P-51 Mustang Reno Racer

P-51 Mustang Reno Racer

I just finished reading an article in the  recent publication of Model Airplane News. The article related to the up coming film by George Lucas: The Red Tails. The article was authored by John Reid and I found it to be very informative and illuminating. There is a lot of misinformation regarding the Tuskegee Airmen and I […]
Hangar 9 E-conversions: P-47, F4U Corsair & F6F Hellcat

Hangar 9 E-conversions: P-47, F4U Corsair & F6F Hellcat

I have had the good fortune to assemble many  Hangar 9 models and have found that they have enough scale details to satisfy any pilot without compromising the performance of the airframe. They are also some of the easiest planes to do e-conversions on because the airframe is light for its size and allows for a great […]
V-22 Osprey Build Update #3

V-22 Osprey Build Update #3

This evening’s task is assembly the frames for each nacelle.  If you’ve built a couple of non-ARF helicopters in the past there won’t be any real surprises here, but definitely follow the instructions as the Osprey doesn’t function like a normal heli. A note of clarification:  One tends to look at the nacelles in their […]

RotorMast.com V-22 Osprey Build-Along

One of the most impressive helicopter-related products at the 2011 Toledo Expo was the RotorMast.com V-22 Osprey.  I’d read a good deal online about this remarkable design, and I’d seen a number of online videos as well, but seeing it in person I gained a clearer understanding of the careful thought and effort that went […]
