About this Plan

Westland Whirlwind. Radio control scale model WWII fighter, for twin .30 - .40 engines and 4 functions RC. Scale is 1/8.

Quote: "Near-scale twin's a beauty! 65 in span, for two .30's. Westland Whirlwind, by Dave W Cronin.

WESTLAND WHIRLWIND! No, not the chopper but a twin-engined fighter-bomber of World War Two. Having flown Super Sixties (oz552) and the like for about three years, I graduated to low wing models by building a Mustfire (oz6365) - finished to resemble a Mk. XIV Polish Spitfire. After learning to fly this, there came the Japanese Hein and then a Hurricane. This latter was flown in the Gravesend demonstration team, as well as being a familiar sight on our local flying ground. After a while, my clubmates started getting at Dave Cronin and me to produce something 'out of the ordinary' from WWII - knowing our liking for aircraft of that period.

The pressure, in fact, became so great that Dave and I spent several evenings, at his flat, looking over all his aircraft recognition books, reference works and so on. The only machine that looked good to us and had not been 'done before', was the twin-engined Westland Whirlwind, an unusual and striking aircraft, brimming with that elusive ingredient - character.

Dave is the design department of our team, so he got cracking over a hot drawing board and came up with the plans you see here. As you will notice, the model is not intended to be dead scale, since we like our planes to be everyday sport flyers, not something kept in moth-balls for those two occasions per year. Most noticeable departure is probably around the tail end. On the full size machine, the rudder was in two parts, above and below the tailplane. To simplify things, we have made it a one-piece control surface, with a cut-out in the elevators for rudder movement. Those who are offended by this can always built it in the scale way if they prefer. The undercarriage has been shortened, and moved forward, and the nacelles slimmed slightly, and there are other slight departures. But, you'll agree, the essential and very distinctive character of the Whirlwind is there in plenty.

The construction is quite straight-forward; both crutch and spine systems are used for the fuselage and nacelles for accuracy of assembly. The wing is really beefy around the centre section and keyed into the nacelles, where the vibration and landing shocks have to be absorbed. The whole model is sheeted, yet the fuselage and tail unit are surprisingly light. With a little forethought, the building sequence of fuselage, nacelles, wing and tail can be dovetailed to allow plenty of time for the glue to set, without holding up proceedings..."

Hi Steve, I recently got that plan. I have had it laser cut, haven't started building yet,

Brian, I would love to get laser cut set. Your cutter still around?

Hi, I would love to get a copy of g code or stl laser cutter file as I have access to a laser cutter.

I had a wood set cut at Braincube aero models in 2017. Service quality and delivery excellent. Have built an electric version which is now in the final assembly stages. The build write up wasn't a great deal of help.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
