Octocopter
My octocopter is ready.
Here you can download the FreeCAD file okto_flower_star_3.fcstd
The housing is made from 3mm wood with a laser cutter. The parts fit perfectly. No glue needed. But it is fixed with a steel thread rod.
The rings are made from XPS foam. Two templates have been cut out with a laser cutter. They have benn put on top and bottom of the foam. Then I was able to cut it out with a hot wire.
The 8 ring holders have been printed with a 3D printer.
The arms are made from aluminium and will be replaced by CFK some time.
The electronics is some more or less old stuff I had lying around: A pixhawk 2.4.8 flight controller with GPS, NG-UAVP 4mini brushless controllers, A LED stripe with192 WS2812 LEDs and an arduino nano for LED control, A 7000mAh LiPo, ...

Re: Octocopter
Looking good.
P.S. Will it fly?

Re: Octocopter
Nice.
P.S. If you will ever have some videos online. Don't forget to share.

Re: Octocopter
I second the request. Would love to see this fly. Very impressive.
In the FreeCAD file I see a camera attached. Is this meant to retract before landing or will you add some sort of landing gear?
Re: Octocopter
It is not finished yet, but I will try to retract the camera. The camera will be mounted with a 2 axis gimbal with brushless motors. The gimbal controller has inputs that can be connected to the remote control receiver. One channel can be used to control the pitch. I will try out if it can move the camera above the ground level of the octocopter.

Re: Octocopter
Hi,
very nice project!!!
As you may see from the screenshot, I started to design my own quad-copter, but I'm stuck with commercial components.
I was able to find some of them by using grabcad or onshape database; but I can't find any datasheets or drawings for items like: motors, blades, gps, ECS, etc..
On supplier web sites you can find some technical data, but it's hard to find technical drawings.
May you suggest me some link where can I get some 3D model or 2d drawings of commercial parts and datasheet too?
How did you you model these items?
Thanks for your help.
Regards
Michele

For propellers, here is a guide how to model them: https://forum.freecadweb.org/viewtopic. ... 0#p270716
