About this Plan

Snow White. Free flight sport model, with easy build sheet balsa construction. For .75 - 1 cc power. From Aeromodeller, May 1955.

Quote: "40 inch free flight design with new easy-to-build sheet fuselage construction featuring tongued formers and slotted sides.

SNOW WHITE was designed primarily as a good looking sports model. Construction is strong and simple and can be tackled with confidence by anyone with even the most limited experience. An E.D. Bee powered the original, but the Mills .75, Allbon Merlin or Spitfire can be substituted. The designer has had hours of trouble-free flying with the all white prototype and trimming is simplicity itself.

Construction. Start on the Fuselage by cutting out all the formers and the 3/23 in sheet sides. Check the former tongues in the notches in the sides. Bend the undercarriage from 14 swg piano wire and bind to the ply formers with thread. Join the sides with the formers, cementing carefully, especially around the ply joints and cement in the hardwood bearers.

When dry, drill the engine mount holes and fix the 6 BA bolts. Add the 1/16 top and bottom fuselage sheeting, celluloid windscreen, dowelling and ply tailskid. Bind and solder the undercarriage legs together and construct the cowling as detailed.

The wings are quite straightforward. For ease of construction, the wing thickness does not taper. Thus the ribs only require tapering rear of the main span. The wing section is thin to give a fast scale flying speed. Start construction by notching the TE and pinning it down on the plan, followed by the rear spar, wing ribs, 1/4 x 1/4 LE, and the main spar. Use hard stock for the spars. Cement the 1/32 LE sheeting carefully to the LE, ribs and the main spar. Build the centre section incorporating the ply dihedral brace and cement the wing panels in place, leaving them to dry at the correct dihedral angle..."

* 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.
