About this Plan

Frog Interceptor MkIV Shoulder. Radio control sport model, for electric power. This is a modern-day plan, but the subject is an interesting vintage model aircraft.

Quote: "I've been scratching around for a candidate for BBCC5, and every time I think I've found one, I discover that there's 8 build logs of 4 configurations, and 2 sequels of the bird... So, I started looking down through the list of airplanes in the Flight Archives tome compiled by Lord Librarian Terrell along with the plans on OuterZone, and found this little girl. It's apparent she was a 1930's rubber powered Frog Kit of a fantasy fighter aircraft named the Wilmot Mark IV Interceptor, but there doesn't seem to be any drawings (or formers... LOL) other than the 3-view... to that end I've developed a set for a 60" version (approximately 1/8 of the 'proposed' scale). You know how I like one-off's and/or never-built's I really like her, but (there's always a 'but') I think she looks better as a parasol with spoked (yeah, yeah, I know) wheels than as a shoulder wing with smooth rims. I've attached the drawing sets of both the original shoulder version and the parasol version along with the 3-views of both variants... of note, the fuse bears a striking resemblance to a Thunderbolt. I'm not sure if these meet the requirements for posting, but if they do, you're welcome to them..."

Direct submission to Outerzone.

Update 18/06/2014: Replaced this plan with latest version.

Quote: "Steve, I revised the drawings to show a slightly more narrow fuse (less than 4in), a better aileron setup, and true wire lengths for the undercarriage... I promise to quit messing with the drawings now!"


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

I always wondered why the RTF ‘Frog Fighter’ was Mk V. If anyone recalls that, it was round about 1950, had a thin aluminium body and bond paper wings and tail feathers. For a kid like me back then, the geared prop and the built in winder (the box had two cut outs for the wings and a gear box at the front that let you wind up the rubber) was definitely ‘high tech’.

* 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.
