Installed the stock electronics on a larger and lighter Bluecor fanfold airframe. Elevons and differential thrust, as on the original, along with the barometer module. Span is 21.5 inches, length 15.25 inches, and all-up weight is 168 grams with a 2S 50C 800mAh LiPo. I like the performance much better than the original higher wing loading. This is about 30 grams lighter than the original.
