Trainer. Single or multi-channel trainer, for .19 to .40 power. Wing area 618 sq in.
Quote: "Designed specifically for the beginner or newcomer to RC, the Apprentice permits all the normal errors of building and flying and still has that extra something for the good flight. Apprentice, by Bill Northrop.
The Apprentice was designed specifically for the model builder who has decided to move into radio control. It was particularly designed for the beginning R/Cer who is located in a low R/C activity area and who will not have the help of an experienced pilot during the first flights.
On the other hand, the Apprentice is the perfect ship for the verteran R/Cer to build for his young son who is showing that significant gleam of interest in his eye. And by the way, if your wife or girl friend has finally given signs of resigning herself to her fate and wants to 'try it sometime,' build her a pink Apprentice and put curtains in the windows.
To suit the above requirements, we felt the ship needed an important design factor that has been left out of most present day 'trainers'. The plane should be large enough, and light enough, to fly steadily and slowly, giving the new pilot time to think about his next control movement.
This design consideration also provides another important factor missing in most so called beginner's airplanes. It is no particular problem for an experienced flier to have a somewhat badly trimmed airplane on its first flight, but the beginner has three strikes against him right at the start: an untried airplane, an untried radio (the bench and the air seem to be unrelated as far as radio operation is concerned), and an untried pilot. A large, lightweight airplane will permit test gliding, an almost forgotten art as applied to R/C. Through a series of test glides, the plane, the pilot, and the control system all have a chance to become acquainted with each other under less strained conditions, so that when the big moment occurs, that first powered flight, there is a better chance of survival all around. Most any experienced R/C pilot, if he's willing to admit it and can accurately recall his first controlled flight, will go along with this.
Another point in favor of a large, light airplane like the Apprentice is that it will take almost any kind of radio equipment. If the new R/Cer is fortu-nate enough to be able to afford a multi proportional system, there is no need to feel obligated to install it in a typical multi bird for his first flying lesson, nor should he feel obliged to work his way up through the single channel route. In the long run, if you are pretty sure of ending up with multi propo equipment, it would actually be cheaper to start out with it. Work your way up through the airplanes, not the radios..."

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.
