About this Plan

Eaglet 50 - Radio control trainer.

Quote: "Steve, Attached are the files for the Eaglet 50 edubarca is looking for; found a set of plans on eBay not long ago, and finally got 'em scanned. Formers are incomplete, but it's a basic fuselage, and the wing ribs are pretty much the same all the way thru. Parts sheets drawings are in the manual, which is a free PDF download from Great Planes, on their website under Discontinued Kits at http://www.greatplanes.com/manuals/discontinued.html."

Direct submission to Outerzone.

Update 28/04/2018: added kit review from Flying Models, June 1982, thanks to RFJ.

Hi Steve, I built an Eaglet 50 as my first powered plane many years ago. It was easy to build, and I remember the manual as being organized and useful. It might make sense to make the fuselage out of balsa instead of 1/8" ply, unless you can get it laser cut or you have a router and like to use it. A balsa fuselage without the big holes might be slightly quieter, unless one were to use an electric motor with a well balanced prop. The interlocking tab feature worked well, no risk of a banana fuselage. For scratch building it seems like it would be a lot of trouble. On the other hand, when my radio went bad one day the fuselage proved to be pretty durable in a crash. For me, the Eaglet was easy to fly. Prior to that I had only flown light two meter gliders. Because of that experience, I found it MUCH easier to land dead stick than with power. As with many trainers, I'd recommend a low pitch prop and a motor with a low idle. Otherwise the approach path can be shallow, which is a problem inherent in light slow models with glo engines. Obviously not a problem if you use an electric motor. I am skeptical that it would fly ok with the minimum recommended .09 engine. The .20 I used was more than enough, although I doubt if any reasonable choice would actually make it fly very fast. A small 4 stroke would be ideal, though I don't remember how big a prop would have adequate clearance. I'm not sure why they dropped this kit as it's one of those designs that got it right.

@Lincoln: Depends on the brand of .09 engine. The Enya .09 would fly the Eaglet on three channels just fine. I am on my 4th Eaglet. This one is powered by a Turnigy 480 850kv, 9x6 Parkzone 9x6 prop (ala Wildcat), and either two 1600 3s packs, or a 2200 3s. That access hatch, in the nose, sure makes quick work of changing batteries! My first Eaglet started out with a belted Speed 600 can motor, and graduated to an AXI 2820. WAY plenty power, with the AXI! Had decent "trainer" performance, with the 600, on 7 round cells.

Steve, I just wanted to thank you for providing me the original plans for the Carl Goldberg Eaglet. Several years ago I came by a severely damaged Eaglet and because of your plans I was able to completely restore it. She flies great! Here's what I got originally... Here she is, restored [see more pics 005, 006]. She has since flown - more than 10 flights so far, and every one was great. Thanks again for the plans.

Here are a couple pics of my Eaglet 50 built from a Balsa Workbench short kit and plans from Outerzone [more pics 007, 008]. It's powered by a Magnum .15. The Eaglet was my first RC plane back in 1982. Had a lot of fun building it and it flies great! The hardest part of building the short kit was fabricating the windscreen and side windows. Thanks for a great website!

* 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.
