Hi,
I worked on this UAV a very long time ago. Power efficiency was good (I think it was around 80W/kg). Stabilisation outdoor difficult, probably due to shroud and/or bad autopilot.
Best regards
Nicolas

did anyone before succeeded in building a Y4 Copter with a coaxial front

Would be really great to get some ideas on that topic.
Thank you very much,
Kevin
