Time Machine (oz9639)
About this Plan
Time Machine. Outdoor 1/2A free flight design.
Quote: "Designed to a proven concept, the Time Machine is a balance of frame and forces intent upon performance. A 1/2A Competition Free-Flight that takes a back seat to nothing. 49in in span, for a screaming Cox Tee-Dee .049 to .051.
Since Young Don returned to the contest scene after a few years' layoff, things have gotten a lot tougher for us. One reason, besides Young Don's considerable competitive skill, is his design philosophy. He sticks with things that work rather than overly concerning himself with theoretical trivia. He is much less interested in starting new trends than he is in winning - the result is straightforward designs of which the Time Machine is a glowing example.
This design follows most of the latest popular trends: aft rudder, parabolic wing and tail, low pylon, geodetic birdcage construction, remote dethermalizer and light weight, combined with moderate (300 sq in) wing area. The climb is not the fastest and the glide is not the slowest, but the blend is deadly.
A multiple national record holder as a junior and a senior, Don, now 23, has lots of fresh techniques and ideas you will find interesting. He is too busy designing, building and flying in preparation for the Nationals to mess with writing this text, so my translation of his thoughts on construction and trimming will have to suffice... "

* 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.
