Philcan Sedan (oz9716)

About this Plan

Philcan Sedan. Radio control sport model for 20-40 four stroke power and 3 - 4 functions.

Quote: "The 'Philcan Sedan' came about as the result of my search recently for a new model that could be used by my school's modelling club members as a trainer. I wanted the model to be a little different, though, perhaps looking like a 1920s passenger aircraft with an open cockpit and simple lines. My first drawings had the model fitted with ailerons and a power unit of up to a 40 four-stroke.

This specification was changed during construction to a three-function model with a 20 two-stroke or four-stroke for power; the O.S. 20 four-stroke I eventually used was intended for an Aeronca C1 scale model at a later date and I thought that it would be a good idea to give it some flying time before fitting it into the scale project. The O.S. 20 is a super little motor with more than enough power for the 'Sedan'.

As stated earlier, I had originally intended fitting ailerons to the model; as it turned out, I didn't have time to build an aileron wing but I have drawn in the details on the plan for anyone who wants something a little more exciting! Note that in the aileron version the wingspan is reduced.

As I was hoping to receive assistance from the club members when building the model, I kept the structure as simple as possible. The wings are, perhaps, over-engineered but they are very strong and can be covered with anything from nylon to Solarfilm.

Let's get started. The wings are of balsa construction except for the plywood dihedral braces. I used a ply template for the ribs which are cut from 3/32 x 1/8 sheet (all dimensions here are in inches, incidentally). The bottom part of the trailing edge and the two lower spars (on 1/16 packing pieces) are pinned directly over the plan which is first protected with polythene sheet (I use the backing from Solarfilm or Solartex). The ribs can then be glued in the correct positions; I always use white pva glue for this type of built-up construction.. The top spar can be added when all the ribs are in place, along with the leading edge; note that the root rib is angled for the dihedral..."
