About this Plan
Ferdinand. 15in span all-sheet C/L model, for .5-.9 diesels. From Aeromodeller September 1959.
Quote: "ORIGINALLY DESIGNED FOR the McCoy .049 'Duroglo', this pert little model biplane suitable for any British diesel of 0.5 cc to 0.9 cc capacity - just right in fact for the new .049 glow engines about to hit the market.
Begin by making up the engine and undercarriage assembly. The undercarriage is clamped between the ply faces of the engine former. For radial mounting, drill through to take the engine bolts, which are held secure by soldering the piede of tinplate across them as shown. Beam mounted engines require two bearers, which are cemented to the engine former and former 'A', fitting into the slots as detailed. Next, add the fuselage sides, lining them up accurately at the tail. The top front edge is then formed by bringing the sides together as shown in the small sketch. The gap is filled in with in. sheet. Now fit the tank in position, with the fuel tubing running out through the fuselage side to the engine spray bar. Do not add the top and bottom decking until the wings and tailplanes are fitted.
Flying surfaces are made from sheet, the wings being sanded to section, but this is not critical. Cut slots in both wings for the interplane struts, which are made from in. ply. Insert a piece of 1/16 in ply into the lower wing to take the bellcrank assembly, which can now be fastened in place.
Cement the tailplane in its slot; and fasten the push-pull rod to the elevator horn. The wings can now be cemented in place. When these joints are dry, deck the top and bottom of the fuselage, add the fin and interplane struts, and give the model three coats of clear dope, sanding between each coat. Colour dope as required to your own scheme and Ferdinand is ready to take the air.
Balance the model on the front line, and fly on 25 to 30 foot lines."

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

User commentsThere are two versions of this model 1959 for .5 - .8 cc diesels and 1967 for Cox 049. The models are the same size but with different engine mounts and slightly different shaped interplane struts.

* 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.
