About this Plan

Mimi. Free flight power biplane model at only 16in wingspan, by Ray Malmstrom from Aeromodeller Sept 1953.

Quote: "How small can a power model be? This pert little biplane by Ray Malmstrom for the Frog 50 or ED .46 is only 16 inch span. Simple to build and easy to fly. Full details on the next 4 pages.

HERE is one of the smallest, most convenient to transport power jobs yet designed, and moreover, a model that knows all about the business of getting upstairs in double quick time.

Flying fun is a 'built-in' feature of this little bundle of aeronautical mischief. So simple to construct that modellers with a little experience will get all the gen from the plan.

Building hints that follow are really for the beginner, but read them just the same, then you'll see how easy MIMI is to build.

Trace the fuselage parts onto 1/4 sheet and cut out. If you have some 6 in. wide quarter stock, the fuselage can be cut in one piece. To the basic fuselage shape, add the two nacelle side pieces and ply liners in the u/c slot. Cement in position the top wing rear mounting and the angled tail-plane platform. Add dowels and small rear peg.

Before sanding the fuselage, add the engine mounting, drilled ready for your engine. Make sure it is level from side and front views. Add blocks A . Carefully sandpaper all over to the correct sections, checking that you have the necessary clearance in the nose for a 6 in x 4 in propeller. Cement the lower fin in place and the fuselage is complete except for dope and fuel proofer.

Now don't fade away at the prospect of having two wings to build, these are really easy to construct. Trace the LE's onto sheet and the TE of the top wing onto 3/16 in sheet. Cut out, taking care that the notches for root ribs are at a slight angle. Add ribs, using the template for setting root ribs at the correct angle..."

Update 10/09/2013: Replaced this plan with a correct sized version, thanks to AndyLuckett - actually, I just went back to RCG and grabbed a copy of the version uploaded by foamdave.

Update 17/09/2017: Added PDFvector plan tracing, thanks to hogal.

Supplementary file notes

Article pages, text and pics. This is the original plan before replacing. This file includes the original 4 pages of plan drawings as printed, but the scaling will be wrong.

User comments

Firstly, thanks for providing such a marvellous website. Beside building from the plans, I just enjoy trolling through it. This Mimi plan prints out at 112% which gives a wingspan of 18" instead of 16". This has been noted by several different builders using differing computer/printer combinations. We have selected Mimi as the model of the meet for Cowra MAC Oily Hand Day and most of them have been built at 18" because of the way the plan prints. The model of course flies fine at 18" so it is not a problem. Just thought you might like to know we found this aberration..

Thanks Andy, have fixed this now.

Hi Steve, This design is crying out to be modified (scaled up and electric) for todays' R/C flyer looking for something unusual and unique. This could very well be one of my next winter projects.

I hope these photos inspire others to build MIMI [model photo & more pics 006-010].

Notes

* 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.

Scaling

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.
