"Hi Fun Wey,
All of the control boards have a diagram for prop rotation when looking down from the top, to achieve proper angle for the EDF's put an arrow on each boom showing the rotation for each motor then rotate the EDF in the same…"

Remzibi OSD 3DR

I received my Remzibi OSD 3DR today and looking for instructions on how to connect it to my APM2. I can't seem to find any instructions for the electrical wiring on the Remzibi OSD 3DR, there is a…Continue

Ed Kirk commented on Ed Kirk's blog post Ducted Fan Quadcopter"It's my hobby, I do it for fun and experience (and because I can). On the Avatar both front fans rotate like a tricopter rotates the rear unit for yaw control. There is no advantage to this except it really looks cool. …"
JB commented on Ed Kirk's blog post Ducted Fan Quadcopter"Looks great! There is so some controversy in online forums about ducted fans versus propellers, but the general consensus seems to be that ducted fans offer less efficiency and shorter flight times. What would you say are the…"

I use 90mm fans, they all rotate the same, yaw control is achieved by putting some fixed angle on the fans. Currently get about 5 minutes of good flying time on a 6 cell 2600 mah battery. It requires 60 amp…"
Ed Kirk replied to Rick's discussion Prop directions for Tri Copters:"Hello Adrian, I have tried and really want the APM to work. I have purchased most of the extra stuff and the APM2.5 was looking so promising, I was showing off to my friends and it just went off to the right into a pile of rocks,…"
Ed Kirk replied to Rick's discussion Prop directions for Tri Copters:"Hello Adrian, I have tried the APM1, APM2 and APM2.5 and can't trust them. I have had the same problem as you, I get a number of excellent flights and then they do something wierd. I wished they worked properly all of the time,…"

Ed Kirk commented on Ed Kirk's blog post Ducted Fan Tricopter"I have tried different servos and it really doesn't matter, the slower high torque servos are my first choice. I also prefere standard servos over the smaller ones but they work fine, just don't hold up when banged around or abused,…"

Ed Kirk replied to Juan Sebastian Otalora Acevedo's discussion Whats an EDF's??"I must be doing something wrong, I have built several and find that they fly very well. There are more stable and actually very smooth.

Ed Kirk replied to kyi's discussion ducted fan quadcopter"Since torque isn't used to control yaw the EDF's must be installed at an angle so thrust controls yaw.
The instructions (control board) show proper prop rotation, rotate the EDF angle. If the prop rotates clockwise rotate the EDF…"
Ed Kirk replied to kyi's discussion ducted fan quadcopter"
You need at least 30 amp ESC's, I had to use 60 amp ESC's with 90mm EDF even though they don't draw that much current. I think my 60mm EDF has 40 or 45 amp ESC's."

My new camera platform, Y6 with 3 coaxial counter rotating motor/prop setup. Great flier if you are willing to deal with mounting the motors and props. The DJI Wookong is supurb.

Ducted Fan Quadcopter

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.

I really appreciate your thoughts, good to know.
I'm enjoying the challenge, but it has been frustrating at times.
I haven't given up yet and I'll post info go others once I figure it out.
