Can anyone put a date on when this kit first came out? Thanks.

I have the AMA copy of the Great Planes Trainer .40 kit plan and there is no date on the plan. But I would place the date at 1982.
According to the Great Planes website, Great Planes was started in 1982. Most of the Great Planes early initial kit offerings were reworked Bridi plans by Don Anderson. The Great Planes Trainer series was basically the RCM Trainer with a few tweaks. I learned to fly with this airplane in 1984 so it was available then.
The entire early Great Planes trainer offerings were eventually scrapped for the PT 20-40. which was a shame because the Trainer series were excellent flying airplanes. They could fly and land at a crawl and yet do much of the FAI pattern if set up properly. The PT series flew like a kite with an engine, which was OK for learning to land, but not much else.
The original Great Planes kit plan for this model is now in the Academy of Model Aeronautics plan data base. It can be purchased from them with the huge AMA watermark embossed on the plan. Plan# 50951.

* 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.
