Thur May 21 2026 Starting Post
Well, ... this is a continuation of my detailed DeHavilland Gipsy Moth build thread, that was lost to the tragic HPA site crash of Nov 2025. I will post what I can - not all of it - and just carry on from there.
I already have a lot of work done, right up to the framing of the fin/rudder and stabilizer.
I will start with some pics of the Gipsy Moth.

Thanks Chris.
Woops ... now I have 'Gipsy' spelled correctly in the title.
I wanted to jump right up to a 30 inch wingspan "scale looking" biplane, for rubber powered free flight.
Which of three 30 inch biplanes would be my next rubber powered free flight build? The choice was between three Jumbo sized Golden Age era Biplanes, all three being laser cut kits that I already have sitting on the shelf, doing nothing anyway, just wasting away ...
Three kits: The DH 60 GIPSY MOTH, or The STANDARD J-1 , or the STEARMAN PT 17
The three different engine details of the planes are as follows.
THREE DIFFERENT TYPES OF ENGINES
DH 60 GIPSY MOTH 30" Dumas kit #336
DeHavilland "Gipsy 1" four cylinder upright inline piston, single exhaust, air cooled, 100 HP
Pic #1 GYPSY 1B LEFT SIDE FROM FRONT
STANDARD J-1 30" Dumas kit #314
Curtiss Ox-5 liquid cooled V8 dual exhaust 90 HP
Pic #2 CURTISS OX 5 LIQUID COOLED V8 IN STANDARD J1.
The Standard J-1 also had the Hispano Suiza, 180 HP which had a nice chromed out "swan" radiator cap ornament .
Pic #3 STORK ORNAMENT HISPANO SUIZA AIRCRAFT ENGINE
STEARMAN PT 17 28" Herr Engineering kit #116
Seven cylinder Continental R-670 Air Cooled Radial 220 HP
Pic #4 CONTINENTAL R670 RADIAL ENGINE 2
This kit has an all balsa engine, using built up cylinder plates stacked onto the seven crankcase posts. Very cool.
I ended up choosing the Gipsy Moth.

Jeremy .... there is no Cirrus engine .... ::) !?
The Gipsy Moth has the "Gipsy 1" four cylinder upright inline piston engine.
The Standard J-1 has the Curtiss OX-5 liquid cooled V8 engine, and the
Stearman has the Continental R670 seven cylinder Radial engine.
There are other comparisons between these three models, that I should point out along the way, so you can really see the design and structural and plan differences, and take them into consideration, in choosing which model to build.
Well, anyways, here are the two plans of the Stearman PT 17 and Standard J1 for comparison. These two are also at the top of my bipes to build list, now, after the Gipsy Moth ...

These are a few notes to myself to help keep track of things.
There are small number of model assembly build tutorials, within the overall complete build, that I had already worked on, and some were completed.
1 Fuse Jig Fixture tutorial made with balsa base and 3/16" white Ross Foam Board 20" x 30".
2 Hand Made Laminated Balsa Display Prop build tutorial.
3 Flying prop selection.
4 Pilot Selections and painting tutorial. I cannnot find my two Banks pilots, but I have a few other pilots of differing scale, whose shoulders must fit into that narrow fuselage.
5 Soldering the Landing Gear Wire Assemblies tutorial - I have had only one (bad) experience soldering, from not using enough heat .... I will acquiesce, and seek help later with this, from our resident and stalwart soldering expert, Squirrelnet Chris. 'Long live the Core'. 8) It is high time for me to give it a real fearless attempt ... ie no whining or dodging, or beating around the bush, or complaining, or sniveling and niggling, etc. I have a much hotter solder gun to try now.
6 Spoked Wheels. I tried a spoke wheel kit, but failed miserably. But I was lucky. My computer Guru Bob got a 3D printer for Xmas, and he printed me up some very passable spoked wheels, that fit well and match the color scheme. The wheels took a little bit of trimming with an exacto knife - those printed plastic wheel spokes are very very solid, for being so thin. Bob also printed up those two perfectly sized pilots in my 30 inch Beaver.
7 Thread selection and color for the rigging wires.
8 Engine assembly and details.
So those are the things that I can think of, so far.
I'm actually looking forward to modeling in the air conditioning, all day all summer, just like last summer, when there is a drought again with the accompanying heatwave, and the grass drying a dormant yellow, and the ground turning hard as a rock.

Hangar Sign and Angled Brace Support
M and B make a backing stand for the Hangar sign.
First, a little more preliminary work to set the mood for Mandrake and Bloodroot, our devoted maintenance technicians.
The angle brace support is made from 3/16" white Foam Board, and round head pins, and a couple of strips of scotch tape. The actual Hangar sign is a printer color copy with a flimsy 12 thou file folder cardboard backing. It can now sit on any pedestal.
I know that the proportions, of the Gipsy Moth box cover art, in the Hangar pic, are way off (vanishing point lines? ), but I tried to fix it up as much as possible.

Nose Block Cowl Block
Well the E3 tenon did not glue up exactly right onto E2 . I soaked them in hot water for half an hour (these are 1/8" thick). It finally got it "loose" enough, that I just slid it up the width of the pencil line, to the correct scribed lines, and pinned it up to dry. It really was off when I test fitted it to the other parts, so I knew I had to fix it right.
Well, I finally figured out the four pics in this plan cutout picture. It alternates COWL BLOCK NOSE BLOCK COWL BLOCK NOSE BLOCK , instead of COWL BLOCK COWL CLOCK NOSE BLOCK NOSE BLOCK. I colored one orange, and one is pink now, for the visual acuity. Pink is Nose Block and Orange is Cowl Block.
I should have cut out all four diagrams separately from the beginning. 'Little things' that can stump a Senior ...

Nose Block Cowl Block
Pic #1 3366 The round head hook end of the kit supplied 0.041" diam prop shaft 2 1/4" long, the thrust button of 0.3" 7.62 mm and the 8" black prop are shown.
Pic #2 3369 Here is a better view of the kit supplied prop shaft. Here is the rub. The round head rubber end of the wire hook of the prop shaft, is 10.0 mm across, and that wire hook will not go through the 0.3" 7.62 mm thrust button hole in the Cowl Block, for easy Stooge Stretch Winding. I have a heavier and longer prop wire of 0.047" x 2 3/8" long to use, but the hook end is too big also. 0.047" 3/64" wire is the size that fits the thrust button perfectly, but it needs to be longer, and the hook diameter must be less than 0.3" to fit through the thrust button hole in the balsa Cowl Block. Even the Peck Polymers prop shaft #3 size 3/64" x 2.5" is too big at the 'squared' hook of 8 mm ( 9.65 mm 0.380" when measured diagonally) either way - an 8.0 mm or 9.65 mm hook, both, will also not fit through 7.62 mm hole. I have to 'flatten out' or compress that squared hook ... easier said than done ...
Pic #3 3372 We took a few sanding rounds out of the cowl block nose block. I also started looking at my propeller shaft collection - what is left of it. The hook ends will not fit through the cowl block hole, and the kit supplied prop hook is too thin and short.
Pic #4 3375 We got out some 3/64" piano wire rod, cutting pliers and holding pliers, and needle nosed pliers, and a sanding stone for the sharp ends, and proceeded to try and bend up a long prop wire of 0.047" with a flattened oblong hook, that will fit through the Cowl Block hole.

Camo Color Scheme
Well, I started off yesterday preparing for the color scheme and eventual covering of the Beaver, by photocopying more plans, and clear taping the butt ends of the three 8 1/2' x 14", pages together ie one long 3-page of a full wing layout etc., and making a lot of copies, all around, for later on.
In making all those photocopies, I also traced a full length wing outline with ribs, and I am now also considering a new Camo color scheme, thanks to a little inspiration from 'livingroomflight' ! ;D
I intend to keep the same color scheme for the whole plane, but both of the two upper sides of the wings only, will be Camo. I am going with a three color Camo - light blue, even lighter baby blue, and white - on the Camo. Each Camo patch will have a black outline, which should cover up the tissue overlap. We'll see - that's the plan.
Window Tracing
Pic #1 3391 My long, original cut up plan sheet, is taped against the window first. Over that is the blank white printer paper of three sheets of 8 1/2" x 14" taped up lengthwise.
Pic #2 3392 The top third of the wing has just the outline and the ribbs traced in pencil.

Pic #1 3528 This is what I have so far. Iteration #1. Setting up the big vertical board.
Pic #2 3529 Mandrake starts free-handing a new outline design.
Pic #3 3535 Here is the new outline.
Pic #4 3537 Three colors. The background is white. The amoeba-shaped designs are stretched out lengthwise or span-wise, left to right to left, from the 'roundish' shapes in Iteration #1.
The light blue is one pass with the marker. The darker blue is three light blue marker passes on top of each other. No straight lines, no points, and trying to keep the same white spacing distance between the shapes. There is more fine tuning to do.

I stopped the fuse framing for now, and I cleared the building board. There were lots of little mistakes that I marked up and fixed, and I finally squared up the colored panels of the camo design.
I am planning on making five pre-colored Silkspan panels, with a slight overlap resting on the 1/16" thick ribs. I plan to use Sharpie Gel Highlighter "Smear Guard", or "Smear Advanced" to paint up the Silkspan panels with two colors of light Blue. I should be able to glue up a complete practice camo wing, with overlap, the same way as I would do, with the real camo wing. So I will be doing some experimentation with the same Lite Silkspan covering from Brodak.
Pic #1 3573 Rough start to the camo design. The colored panels are not even straight.
Pic #2 3597 I have enough Silkspan to cover the two upper wing surfaces in camo.
Pic #3 3598 Sharpie Gel Highlighter "Smear Guard" - won't bleed and won't dry out.
Pic #4 3614 The Leading Edge Datum has been squared up. The plans are up on the Big Board.

Selecting the right color and thickness of the outlines of the camo designs.
Pic #2 3629 The metallic gray marker is too thick and shinny.

Camo Wing Design Yellow Rib Markers
We are planning the tissue covering overlaps of five panels, using yellow rib marker strips of paper, to mark the spots.
Pic #1 3637 Five panel breaks are to be on the ribs.
Pic #2 3641 med View from the right wingtip down the wing.
Pic #3 3642 med 2 View from the left end.
Pic #4 3645 med rot You can see how shinny the metallic gray marker is. The panels are cut out and located on the orange rib locations.

Here are my top three choices for camo topped wings:
Pic #1 3713 Cloud 1 and Cloud 2 seamless repeating camo designs, have been cut out, overlapped, and pinned to the Big Board, for comparison.
Pic #2 3719 These are the three practice finalists for the blue camo design. They are all cut to size, overlapped and pinned to the big board, and clear taped together.
"Light Blue Camo" is my original in the middle.
Cloud 2 from the net, is on the top. Cloud 2 looks a little bit 'busy' .
Cloud 1 from the net, is on the bottom. Cloud 1 looks more ... like it is actually floating in the "puffy" cumulo nimbus clouds.
Heatwave has started here in the middle of the Great Lakes of North America, along with our 'jungle' humidity. Now, 3:00 PM, it is 89 deg F (feels like 99 deg F). High of 90 deg F today. Humidity is 57% now, but will be 85% by morning.

Fresh Sandpaper
We got out all of the sandpaper blocks and stapled on fresh 100 150 220 sandpaper. To fold around the blocks properly, the 'creases' in the sandpaper were first slightly scored with an awl. Actually, all of my sandpaper cuts were made with several strokes of the awl, using the long clear, cm and mm scale, Safelex Shatterproof Helix rule, 30 cm 300 mm long. File folder cardboard was used as a cutting mat.
Pic #1 3730 Cleaned off the building board.
Pic #2 3734 Sanding blocks to freshen up.
Pic #3 3737 All new sandpaper.
Pic #4 3743 I just used staples to hold them together.
Now we are ready ...

This is going to be an enjoyable build - I can tell right away. :) All of those tiny laser cut holes in the balsa parts are all 3/64" 0.047" 1.8 mm. These holes are for the rigging and control wires ! 8) And the kit has very comprehensive rigging wire diagrams and instructions. This is a very modern kit that was released in 2016, and now ten years later, Dumas has, unfortunately, closed up shop. :(
Pic #1 3747 All of the big long wing copies and files etc. are pulled off of the Big Board, and stored in the long 'Gipsy Moth Plan Copies' folder(s) above the Big Board.
Pic #2 3749 Note the tiny holes in the balsa parts for the rigging wires, and for the control wires, holes and slots.
Pic #3 3751 My notes are written on the plan, in pencil.
Pic #4 3752 The Landing Wires, and the Flying Wires are not labelled in this pic, but they are labelled in Pic #3.
