Works amazingly well. Thanks Benjamin.
Take offs are a little tricky, easier to hold and release. Also, you don't want to drop altitude too fast when outside, or torque spin / prop wash will have you printing more legs.
I used a 4S 850mah battery with an EMAX ECO II Series 2306 2400Kv Motor. A little loud, but works great. Everything else the same as the list on hackaday.io
Might try to cut some carbon fiber parts for more strength, add a GPS, etc.
Tips: Follow Benjamin's guide on Hackaday, all the info is there. Make sure battery is perfectly centered. Have someone hold the drone off the ground and release when you are at 40% throttle for an easy launch. The flaps move in the opposite direction that you think they should.
MotorPin#1 = Back servo
MotorPin#2 = Left servo
MotorPin#3 = Front servo
MotorPin#4 = Right servo
Print (2) sets of the frame, as you will probably break the first as you get the hang of flying this single rotor drone.
