Porterfield Collegiate CP65 - Sport scale model. Wingspan 47-1/2in, for .15 to .19 engines and 3 function radio control. RM Flight Training Course. From Radio Modeller, February/March 1985.
Quote: "CONTINUATION OF THE RM FLIGHT TRAINING COURSE now involves the building and flying of the Porterfield Collegiate, a scale model of a high wing monoplane. Why a scale model? The majority of R/C modellers will, at some time during their modelling activities, want to build a scale or semi-scale R/C model. Indeed, one of the ever present problems is that newcomers to aeromodelling want to build a scale type as their first model - and it can take a lot of effort to dissuade them. But building a scale model, such as the Collegiate is not an end in itself. Constructing the model and learning to fly it will introduce you to some new building techniques, increase your building skills and improve your flying ability. It is a natural progression from the 'Trainer' and the 'Aerobat' to taking you towards becoming the 'complete aeromodeller' - if it is possible to reach that exalted status!
Scale models normally involve more complex airframe structures and the Collegiate is no exception. Being relatively small and utilitising an open structure ie not fully sheeted surfaces or GRP and veneered foam materials, there is a fair amount of intricate work to carry out. Precision is important in the cutting of the wood parts, the bending of the pianowire components and the assembly of the airframe components. Whereas you could get away with parts not fitting absolutely right with the Trainer and Aerobat, this one calls for a high degree of accuracy if you are to have a sound airframe and model with good flying qualities. For instance, there are quite a number of butt joints between longerons, uprights and crosspieces on the fuselage and if we are to end up with a structurally sound fuselage these joints must be well prepared. Gaps between the mating surfaces will inevitably lead to weakness - even when adhesives with gap filling qualities are used.
You may find some of the areas of construction rather 'fiddly' and they may try your patience more than somewhat. This is all part of the excercise of improving you basic modelling skills. When it comes to fitting the radio equipment you will again find that it is not 100% straightforward; the installation must be fully planned (although details are included on the drawings) as there is little spare space available in the narrow Collegiate fuselage. Part of the general Training Scheme the model may be, but it is also an attractive and pleasant to fly model in its own right and well worth the effort of building. For the naturally interested builder the construction and finishing of the Collegiate will be a rewarding experience..."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
