Murphy Rebel – Aircraft of the Month

In the unfortunate trend of homebuilt aircraft companies shutting down in the hyper inflation world we live in another one joined the list last year & last month, Murphy Aircraft.

I covered the M14P Radial powered Moose in July 2023

To give a tribute to the company this months AOC is the Rebel, this is the earlier and most common Murphy aircraft. While not in the limelight like Lancair’s or RV’s Murphy did fill a unique part of the market. High wing, all metal utility planes. the only major alternate in this space is the Zenith 7 & 8 series aircraft. There has always been startups with an offering for this and that but those who make it out of vaporware purgatory, may make a few copies for a short amount of time then disappear.

Like the recent Sonex saga I think this is a good design and is worth saving if a passionate, competent north American business type with more than enough capital can swoop in to re-birth the company.

Founded by Darryl Murphy in 1984 in BC Canada there is significant time span and units built for the brand. The Rebel’s first flight was in 1990 and has over 600 built. it has 700 lbs of useful load in a 2 seat aircraft making a realistic offering in the north American market. The over all shape and surfaces are very simple, a key feature for an off airport aircraft in terms of repairability. This simple construction also give a stand alone immortality to the design as most repair parts can be made independent of the original kit factory, lowering the risk to builders & re buyers in an event like this recent Bankruptcy. Unlike Fabric Covered Cub’s and Dean Wilson derivatives that must be sheltered from the elements for storage, the Murphy’s all aluminum construction means it can reasonably be stored outside in the long term.

With the rare exception of Van’s bankruptcy, Murphy fell into the classic trap of changing owners, changing priorities and vision eventually being procured by by the Chinese company Doufu Group in 2022. There may have been an aviation passionate decision maker on the other side of the globe but my perspective working many aspects of aviation industry over the past 2 plus decades it was likely a “portfolio acquisition” translation the soul is sucked out of it and is on the clock for how long it can exist, very similar to private equity. In this case it was the Duofu parent company bankruptcy pulling Murphy down with it.

YouTube has decent coverage for the Rebel:

No RC options found but with its simple contours a good 3 view and Wiki data would make for an easy balsa scratch build.

Make an Airplane Wing in Rhino 3D

This video shows how to make a complex & accurate Aircraft wing loft for a general aviation / home built / light sport size aircraft.

In this video you will learn about a main source for NACA 6 series airfoils.

The end wing shown in the video has:

25’ span with 3º of dihedral

Scimitar Profile

55” root chord with a NACA 65-415 Airfoil

30” tip chord with a NACA 63-618 Airfoil & 3º of wash out.
