Discussion forum for a community-designed UAV airframe
This is a forum to discuss the creation of a community-designed UAV airframe that can be put into production. Once the basic scope and core participants of the projects have been decided on, we can move the project to a Huddle workspace for the actual design, planning and collaboration.

Having a camera and mounting out in the airstream (see link below) creates a lot of drag. This drag reduces your max speed and flight time. If you could put a clear plastic nose on a plane and an internal camera, you wouldn't have this problem. Everthing would be nice and aerodynamic.

I'm not sure if this will be helpful but looking at the list of desired features piling up in this thread:
I thought it would be useful if we had a spreadsheet that everyone was inputing their wishlist to. This will simplify the process of compiling the data.
Please email CommunityDesignedUAV@gmail.com for invite to the spreadsheet.

@James
Thanks for your explanation.It's clear now for me
@Gerry
Has you have probably seen on this very long discussion, a lot of proposal's and requirements have been done previously.
Some time ago a Workspace was put in place with several people having the required skills to continue this project.
I tried a few days ago to ask what was happening on that Workspace but haven't had a reply yet....

I believe the workspace will get busy once the requirements have been sorted out here.
"Once the basic scope and core participants of the projects have been decided on, we can move the project to a Huddle workspace for the actual design, planning and collaboration. "
I don't think we even have the basic scope nailed down yet.
@Gerry
I think the spreadsheet will help speed up movement to the workspace.

I think we need one or two competent people to focus in the different areas;
Wings (best possible design for max. lift given general requirements of payload, max. weight and dimensions)
fusealage and payload area (max efficiencies)
tail structure (V tail or T tail, perhaps, or part of wing team)
Electronics (batteries, ESC, motor, RX)
Avionics (Ardupilot, IMU, telemetry and sensor placement)

I asked some time ago to be part of this Workspace.
I sent several PM for that and didn't get an answer
I sent some questions for this Workspace to Chris , to understand how this Workspace was working.
I answered me that the team was full and also to wait until they release some of their early work.
So for me this team started to work on this project.
I am interested about this and just trying to get some news of their work....
Best regards, Jean-Claude

ahhh...see you are not only one not in the loop...I guess we wait, everyone is busy with real life, so these processes take time. I know Chris and Jordi are working on the IMU roll-out as well...

@Ron,
Yes I know everybody is busy and I am impressed by all projects and subjects explained and supported here.
I am still in the learning curve and following several discussions and blogs
I was just asking about this community project and will wait for some more news

It will be some time for any one to comment as every one is busy. Appreciate you enthusiasm.

How about this?

Is this idea still alive?
My recommendations would be a design similar to WK2 (white knight two designed by Burt Rutan):
twin electric brushless
twin pods on the intersection between the middle and side sections (power/receiver/autopilot/motor/prop/battery) single payload pod in the middle
6' span, in 2' sections with 6-7 deg dihedral on the outer two sections.
Pusher prop so that you can a camera in the front part of the wing
twin boom
No ailerons, elevator/rudder only (via twin booms)
Straight EPP foam wings, cut via manual or CNC hot wire (easy to do).
Airfoil: Selig 1223
Rudder large enough to compensate for single-engine-out operation.

I think this is a great idea. I would love to have the time to scratch build so I can have what I want but alas thats isnt yet :D
As for ideas I think you would be missing a trick if you didn't have a self contained payload bay (not for flight controls and stuff but for your actual usage payload - cameras etc) in the style of Thunderbird 2. In my notepad doodles for my fantasy plane I have it placed under the CG for ease, balance the plane and balance the payload pod(s) and never worry about it.
