Nymbus 650 Streamlined VTOL Bicopter

Hi all,

My new bicopter prototype - the Nymbus 650 - uses a mod of the original APM airplane code and two fixed-pitch airplane props. Hoping to have your feedback. Here are some clips, some alongside a T-Rex heli, and some partially from the on-board camera:

    Great work.  Very interesting design.   What kind of endurance are you getting with just two motors / rotors as opposed to a quad?  Do you plan on publishing plans and code anywhere ? 

    • Hi Bill.  Thank you!


      I don't have hard numbers for you at the moment.  Props are 13x8 MA 3-bl, and we're planning on a flying weight of < 5 lb


      With the prototype I'm getting about 8-10 min.  But it weighs almost 7 lb.  I'd have to confirm this but I believe its battery is a 5S 4000mAh



  • great work! thumbs up! ;)
    i'm trying to make a bicopter without control board, and since i'm new to RC, i'm unable to understand if its right to connect two esc's to a single battery,...and i want to know how to setup FLYSKY FS-T6 for a bicopter.. with channel mixing for servos...
    please help me out... i'm done with the fabrication of the model.. all thats left is the electronics setup :)
