Percival P6 Mew Gull

Percival P6 Mew Gull

Henshaw

Between February 5th and February 9th 1939, air race pilot Alex Henshaw, flying this specially modified Mew Gull, set a number of records for solo flight between Gravesend London and Wingfield Cape Town, many of which still stand to this very day almost 65 years later. Additionally, Henshaw flew this same aircraft to victory in the 1938 Kings Cup air race, over a triangular course of 1012.14 miles. His average speed of 236.25 mph remains the fastest ever Kings Cup victory.

Inspired by this incredible little aeroplane (the original aircraft photographed here is preserved and still flies) and coming into posession of a set of plans by Brian Peckham, I decided to try my hand at constructing a scale model of the Mew Gull

Construction

With nothing more to go on than a couple of rolled plans and a stack of lumber, this seemed like a daunting task! But with a new (well, old really, but new to me) band-saw and scroll-saw, I had some bits cut out in no time at all!

Plans, planks, ply and some sticks

Fuselage formers

Fuselage formers were quickly shaped on the new saws, and gave an immediate sense of progress to me. This was very encouraging indeed!

I made a few minor modifications as I went along. In particular, I don't like those 'score and crack' formers you occasionally run across in model plans, and I replaced the one in this model with a slightly longer, straight former.

Most formers are 1/8th ply, except for the firewall former and the Cowl former immediately forward of the firewall. These were 1/4 ply.


A few more parts cut from ply on the saws, plus the addition of a pair of beech bearer beams, and the engine compartment starts to take shape.

Shown here with the parts jig-sawed together (no glue here yet) to test the fit, this aircraft will be fitted with a Magnum 80 ringed 4-stroke motor and dimentions are to suit.

A full set of wing ribs for the Mew Gull

Again, the band-saw shone when the time came to cut out the wing ribs!

Tapered in thickness as well as chord, with a graceful curve to the outer trailing edge, this set of ribs was easily cut and the spar notches made in only minutes. Final shaping with sandpaper took only minutes more, and the spar notches trimmed with sandpaper to complete the rib-set.

The eleven ribs shown here are actually doubled -- each rib is two thicknesses of balsa stapled together so a perfectly matching set of ribs can be obtained for left and right wing panels. The pairs of ribs will be separated when wing assembly begins.


Bandsaw, razor-plane, and a sanding drum in a cordless mini-dremem tool are the basis for the roughing out of the landing gear fairing and wheel spats. When roughing out is complete, the inner laminations will be cut away on the underside, to leave a wheel-well.

Look carefully, and you can see two pieces of 1/32" ply amongst all the balsa. These laminations will be on the inside of the outer balsa layers, next to the wheel. This will hopefully protect the thin sides of the spat should the wheel pick up a stone or something and 'process' it through the spat.

Flying

Original Mew Gull in flight

Naturally, my Mew Gull is a long way from flying! Therefore I offer you this photograph of Henshaw's G-AEXF making a landing at Breighton on 15th June 2002. When (If? No! when!) my model takes to the air, I will post a photograph of the event!
