Ducted Fan Quadcopter

Posted by Ed Kirk on May 8, 2012 at 5:00pm

Testing ducted fan quad, flies great.  My intention was to build a tricopter but just had to see how a quad would fly with 90mm EDF's.  Also tested as a "V-Tail" in the quad configeration, it flies with a 15 degree rear facing angle and is more sensitive to inputs.

    Hi. How did you get pusher prop for ducted fan?

    I also interested in ducted fan quad, however, I have no idea for reverse-pitch ducted fan.

    Give me a comment!

    Hi, nice setup.

    Would it be possible to port multiwii soft to apm? I really would like to test it but cant afford to by new hw.

    Yes, same fan, they used to be under $49.00.  Everything except the motor is also available for under $18.00 before shipping and Custome fees.  That's why it is my first choice, I can really "hack" away at the housing and afford to experiment with it.  Sorry about the dirty word "afford".

    Yow, that is a tragic way to mount it.

    Is it this fan you're using?

    The frame is from Multiwiicopter, the Stealth

    Motor/esc's are the 90mm 5 bladed units from Hobbyking

    ESC's are Turingy Plush 60 amp from Hobbyking

    Flight controller is the Quadrino from Flyingeinstein using Multiiwii 2.0 and Arduino 1 (I have invested a lot in the APM1 and APM2, finally gave up) sorry guys.

    3692414113?profile=originalThe fan required a lot of modifications, I am going to re-do them with a saddle attached to the outside.  Right now I use the Multiwiicopter Scarab motor mounts on 12 x 10mm CF arms.  This is a very strong setup but must take away from performance.

    It flies pretty good with a 4S - 2650ma battery and gets about 3 minutes.  It really haules on a 6S and gets 5 minutes with a 2700ma and I have been flying it very hard.  I am sure it will get longer flying time with better motors and move to an external mount.   

    It is not too noisy until I apply some heavy throttle.

     

    I believe there is a future with a shrouded fan, ducted fans are designed to work best at extreemly high RPM, I run well below half of what it is designed for.

    Very cool!  Which battery do you use and how much flight time do you get on a full charge?

  • Rob_Lefebvre May 8, 2012 at 5:42pm

    Wow, that's impressive!  Can you share your recipe?  Which fan units, motors, ESC, and flight controller?  Is that APM?

    It didn't even sound bad! It actually sounded even better than a quad, to me at least.
