Northrop YB-49 Quad 40mm

By far my favorite flying wing to date. Not as agile as the Horten, but it’s easier to hand launch. This wing was not easy to design as the intakes are rectangle slits and airframe has 8 exhaust nozzles! None of that matters because it’s a pretty scale YB-49 and it’s extremely fun and relaxing to fly. The best part is that balancing this wing is no problem! I used twin 1300 4s lipos and I got 4+ minutes and you can use way larger batteries if you like.
