Bird of Time - Sailplane.
Quote: "...first published as a free reduced scale plan in the January 1979 issue of Radio Control Models or RCM. (USA) Designed as an Open Class 118in tow line sailplane, it seems to have had a renaissance of late with a Balsa Kit & an ARTF Fiberglass Fuselage version by Dynaflight."
Update 31/03/2014: Added supplemental eBIRD wing plan (modern alternate high performance wing), thanks to DavePayne.
Update 12/12/2014: Replaced this (the main) plan with a clearer version, thanks to theshadow. Also added alternate version of same plan as a supplement (another good clean scan) thanks to Thermaler.
Update 04/01/2016: Replaced Article file with a more complete copy (fixed missing text on p5) thanks to RogerClark.
Item #1: Article pages, text and pics, thanks to Thermaler, hlsat. Item #2: Alternate version of the fullsize plan, thanks to Thermaler.
Item #3:Plan for eBIRD wing [see more pics 004, 005] - an alternative high performance wing design. Quote: - "Steve, Here is my plan for a high performance wing (non-polyhedral) for the Bird of Time. It has ailerons and flaps so 'crow' or 'butterfly' settings can be used. I would like to contribute it for those people who would want to build an advanced version of the BOT or add another wing option to their current BOT. DXF files for laser cutting will also be available. Here is my build log with photos: http://www.rcgroups.com/forums/showthread.php?t=2125318 The design has been tested and performs beyond my expectations. Using slight amounts of flap adds to the camber for still air and really improves the glide ratio. Also negative flaps helps to de-thermal a ship that is in a monster thermal. Landing with 'crow' makes precision spot landings a breeze. I am the author of the design. DavePayne"
Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
