Jürgen,
Vielen Dank für die Web-Seite. Der QC ist bereits in Teil 2 der Umfrage.
Cheers,

Hey there JES!

Don't know if this one was posted, but it's one I found a few weeks ago in the mikrokopter forum. Its the nanocopter.

You know, this is becoming just a little bit too spooky and Matrix for me. LOL

quad controller with stabilisation for collective pitch rotors


Been looking, but have not seen any development or offerings for controllers for quads or tri's with collective pitch rotors. I can do convention mixing with seperats gyros and such. But looking for some developed product to incorperate most of the equipment. I am not programing literate.
Anybody happen accross any info in this area?

Many thanks,

Alfred

Hi Alfred,
In the first post in the Mega Index of info links under quad projects you will find Redfox74's variable pitch quad build: https://www.rcgroups.com/forums/show....php?t=1187308
and
https://www.rcgroups.com/forums/show....php?t=1211064
Gerorge's Quadpowered board might be able to do variable pitch too, so you might inquire there. No one there has built one that way to-date. Here: https://www.rcgroups.com/forums/show...ht=quadpowered
Cheers,
Jim

jesolins. Thanks for the link pointers. The Quadpowered boards look promising. The others seem to have stalled with little success.
A friend and I are assembling a rather large airframe with approx 30" rotors, with collective pitch. Hope to post some pics and success stories soon.

Thanks again,

Alfred

Alfred,
Did you see the flight video he posted from yesterday in the second link above? I think Red first started posting his progress in February.
Looking forward to seeing your build!
Cheers,

That video did show good stability for the short hop it made. However the project seems to be a modification to another opensource(?) board, and a colaboration. It would require some amount of programing knowledge, of which I have none.

Thanks,

Alfred,
The Quadpowered board would be a good choice for you then. George has been trying to find someone interested in using his board with variable pitch props/rotors. Go for it!

My brain is working overtime, I wonder if using a coaxial bladed system and varying the speed between blades would have the same effect as a variable pitch prop system? Hmmm?

reverendrichie,

I'm not sure exactly what you're getting at. There are a few multirotor vehicles out there that employ two co-axial rotors per arm (such as this one http://www.draganfly.com/uav-helicop...pecifications/).

Collective pitch results in a much quicker application of thrust than increasing the rotor speed. Due to the combination of the rotor inertia and the time it takes for the flow to accelerate, there is a significant delay in changing the thrust in a RPM-controlled system. Also, thrust vs collective pitch is a linear function, whereas thrust vs RPM is a quadratic function.
