Nymbus 650 Streamlined VTOL Bicopter

Posted by Gary Gress on September 4, 2011 at 1:22pm

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 :)
