Olympic 650 - Radio control glider. R/C trainer. Published by RCM, also kitted by Airtronics.
Quote: "The Olympic 650 is a high performance sailplane featuring easy assembly and convenient size. The design was developed with the novice in mind, with a simple to build and rugged structure and forgiving characteristics. The Olypic 650 is quite stable and is recommended for those with no experience with R/C models.
The structure or the Olympic 650 is quite similar to that of the Olympic II (oz5116), and has proven to be strong enough to survive poor landings and to be easily repairable in the event of a crash. The three piece wing design employs a one piece center section which is virtually indestructible, while the plug in tips serve to make the wing easily transportable even in small cars. In fact, when built with the removeable tail option, the entire airplane can be transported in a box measuring 4 x 14 x 40 inches.
The fuselage is a simple slab-sided box which utilises 1/8 air-ply sides and floor for strength and light weight. The tail is a straight forward anti-warp structure with separate control surfaces for simplicity. Details are shown for glow and electric powered versions. The Olympic 550 performs well with either or these power systems, but the Simpler sailplane version is recommended for the novice.
Construction Notes. To build the airplane you will need a flat work surface at least 11 in wide and 48 in long, into which you can push pins. A sheet of Celotex or similar composition board material, works well. Whatever you use, be sure that it is straight and unwarped.
Construction. A few simple tools will also be needed. These include a model knife and/or a supply of single edge razor blades, a razor saw, pliers, a small hammer and a hand drill and drills. You will also need hardwood sanding blocks and assorted grades of sandpaper, a small block or razor plane, a supply of straight or tee-pins and masking tape.
The types of adhesives used are a matter of personal choice but we don't recommend normal model airplane cement. For general construction, we suggest the use of aliphatic resin glue such as Wilhold or Titebond..."

* 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.
