About this Plan

Trainer 40. Radio control trainer model. Wingspan 59 in, wing area 634 sq in.

Discontinued kit from Great Planes.

Note this here is a scan of the Trainer 40 plan as supplied with the kit. See Trainer 40 (oz10529) for a later redrawn version of this plan, in both vectorPDF and CAD format.

Instructions file (40 pages) is very detailed, with step by step build photos.

Quote: "There's no better place to start than one of Great Planes' Trainers when it comes to building your first R/C model airplane. These Trainers are extremely easy to build. The machine cut and sanded parts go together fast and accurately. And accuracy is important when building a model; you need a straight wing and fuselage to assure that the model flies straight and true. The design of the Trainer with its large wing area and long tail moment offers stable flight which is very important when learning to fly. We urge you to build on a flat surface so you will end up with a model with no warps or twists.

This photo instruction book will take you through step by step from start to finish. It is suggested that you read through these instructions and identify and mark the parts before you begin assembly. Refer to the plans and parts list for actual sizes of parts and materials needed to finish your model, whether it is the Trainer Twenty, Forty or Sixty..."

Direct submission to Outerzone.

Quote: "I promised to send you the original plans for the Great Planes Trainer 40 when I got them scanned. Well, I finally had a chance to get it done today. Here's the plans."

Update 30/10/2024: Added CAD zipfile, thanks to Ariel Lempel.

Quote: "Hi Mary, I hope you are doing well. Attached is a dxf file with the parts to laser cut to build the Trainer 40 OVER THE ORIGINAL PDF PLANS already in Outerzone (oz12744). So it could be put as a supplement to that plan. The cuts also include the sticks. In the dxf you will find a text with an overview and comments. Also attached photos of the model built and all the balsa sheets already laser cut. Best regards, Ariel Lempel"

Hello Mary, I can't seem to find the very useful .dxf file mentioned here by Ariel that gives all the parts individually as in 004.jpg, maybe I'm missing it somewhere? Thankyou.

Notes

* 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.

Scaling

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.
