About this Plan

Walthew Rubber Model. Beginners rubber sport model.

Quote: "Especially for the Beginner, Part VIII. The Walthew Rubber Model.

NOBODY should start his aeromodelling career by building a rubber model. Your very first model should be a glider, for gliders are easier to build and fly than any other type of plane. But if you have had any experience of modelling - even if you have only built and flown one model before, then you will find very little difficulty in making a success of the Walthew Rubber Model. And if you have built the Walthew Glider (oz4573) then you will find this present model simplicity itself, since the design is basically the same.

For more experienced modellers who want an easy-to-build contest winner, it should be mentioned that Roland Scott's original design was much lighter than the one given here, the basic fuselage structure being in 3/32 strip, and weight being saved wherever possible in gussets, sheeting, grade of wood, etc. With a prop, this version climbed like a rocket on four strands of 1/4 x 1/24 in rubber, and a three minute flight in still air was absolutely guaranteed every time. So if any old hands want to build it on those lines, they should be more than pleased with the result.

In adapting it for a beginner's first rubber model, it was decided to strengthen the construction in spite of the extra weight. The per-formance is still very good, and as for the strength - well, this is easily the toughest rubber model l have ever met.

Building the Fuselage. Cover the plan with grease-proof paper, and pin down onto level work-board. Lay the top and bottom longerons all position, using straight pins on alternate sides to make sure that they follow the curve correctly. Cement them together where they meet at the extreme tail. Lay a piece of 1/8 in square strip across the longerons immediately over the places marked for spacers, and cut four identical spacers for each one marked..."

Quote: "Here is the August 1950 AEROMODELLER with ...also the long running series 'Especially for the Beginner' by Rev.F.Callon and Roland Scott. This had the WALTHEW RUBBER MODEL to constructed by those now past the simple glider stage. A very comprehensive build and trimming article came with the plan for the 29-1/2 inch wingspan vintage offering. A great first such model to cut your teeth on."

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

I have cleaned this one up a bit, but it still looks bent out of shape. Recommend caution and some careful measurement before building on this plan.

* 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.
