About this Plan

Twin Lizzie (Twin Lizzy). 1/2A gas free flight by Keith Laumer originally from 1959 MAN. This is a modern redrawn plan by Gene Rock.

Quote: "For 1/2A engines - and the little Pee Wee is just fine - a joyful free flight design for sport flying. Has character all its own - Disney character, maybe?

It's a perfect day for flying, the runway is smooth and the air is calm. Engine humming, Twin Lizzie starts her take-off run; the tail skid clears the ground, and with a tentative bounce, she's airborne, climbing steadily in a wide turn that brings her back directly overhead with 50 feet of altitude. The sun glints off her side, as she swings past to make another circle, climbing 100 feet before the engine cuts. In the glide, the ship drifts back toward the runway rocking slightly in an occasional gust, to float in to a perfect landing, ready to go again.

That's the way Twin Lizzie flies, and construction is easy, with a simple box fuselage, sheet balsa tail surfaces and constant chord wing. If you're a beginner or an old timer you'll find Twin Lizzie fun to build and fly.

Fuselage: Let's begin by cutting out the sheet balsa fuselage parts. There are two plywood parts, two 1/8 sheet balsa parts, and seven 1/16 sheet balsa parts. Lay out the first side directly on the wax paper covered plan, cutting two of each piece as you go along. The second side is built over the first, and the two sides are allowed to dry before removing from plan, sanding and separating.

While the sides are drying hard, bend the 3/32 wire main landing gear to shape as shown on plan and lace to plywood part No.4 With No.30 linen thread, coating lacing heavily with cement..."

Twin Lizzie at 147% [see more pics 006] We used a 'spring and string' pull system for the twin rudders, works great, she's in her second year with hundreds of flights, one of my fav's from when I was a child, I had Laumer's book but never got to build it so I waited 50 years.

Hello, It's my Twin Lizzie [see more pics 007], built in 2012, driven by electric, great flight. Regards,

Attached is a photo of my "Twin Lizzie x2" [more pics 008].

Twin Lizzie x2 [more pics 009]. Drew my own plans in 1990. Has been powered by glow fuel 2 and 4 cycle (5 different) motors, diesel and electric. The airfoil section I used is from the Sig Kadet. The model is covered in Super Monokote including the side windows which are clear Monokote. G-AFAW was supposed to be riotously funny but, unfortunately, my American brethren appear not to know the meaning of guffaw.

Here is a picture of my Twin Lizzie that you may wish to add to the Outerzone site [more pics 013]. I lengthened the nose to balance with a light motor and added ailerons for four channel electric RC.

For those who don't know, Keith Laumer was, as well as a prolific model designer, a popular author. I read many of his books back in the day, available in paperback, some made into movies. My favorite was "A Trace of Memory", shouldn't be too hard to find, can't put it down. His later works, after he suffered a stroke, were never quite as entertaining. Any of his titles from the 50's or 60's are stem winders.

He also wrote a book "How to Design and Build Flying Models" published in 1960 and revised in 1970, as well as having plans published in Aeromodeller as well as Air Trails, Model Airplane News and Flying Models. Now if anyone can scan a copy of the book, I'd love to see it

Your wish is our command, Daithi! We have Laumer's How to Design & Build Flying Models over on RCLibrary.

Here's a picture of a Twin Lizzie I bought second hand [main pic] if you wish to use it on Outerzone.

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.
