Took the YF-60 BLACK MAMBA back out for some morning air. In case you missed the previous videos this foam park-jet is based on Lockheed Martin's 6th generation concept drawing which they published as "Miss February" in their 2012 company calendar. My park-jet which I dubbed the "YF-60 Black Mamba" is 43" long and has a 30" Kline-Fogleman wingspan. She's powered by a Grayson Hobby MJv3 and flown on a three channel set-up with two servos moving four control surfaces. PDF plans are posted here: http://www.mediafire.com/download.php...
