About this Plan

Olympic 650 Electric. Radio control sailplane for electric power.

The original Olympic 650 (oz6040) was a 1981 Lee Renaud sailplane design, published by RCM and later kitted by Airtronics. This here is a later redrawn version, modified and redrawn by John Torrance for electric power using a brushless outrunner.

Direct submission to Outerzone.

Quote: "Hi Steve, glad you like the plans... as to other plans I attach the next one. The drawing is self explanatory and is an electrified version of the Olympic 650 glider. This plane has won several contests in the past and I still own the original (still flying after 30 years). Hope you like it, it is a great flyer.
Regards from Bannister, Western Australia,"


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Hi, I am building a 2 metre version as described in the "RCM Sailplane And Soaring Manual" mentioned in the Airtronics manual with OZ 6040. However there is no mention of what brushless motor , Lipo, or prop was used on the electric version. I looked at the "Saggitta 600" plan Oz13155 and that uses A "OS3815 1000KV" motor with a 3cell 1800 Lipo battery. But no mention of what size folding prop is used. I am also fitting spoilers to my version and using the original tail plane length because of the extended wing.
As my original flying was done in the 1980's I am looking for some help in understanding the black magic art of electric flying and would appreciate guidance in selecting a motr, battery, and prop combo. Will send photos before inaugural flight and notes on my experience flying it.

* 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.
