Ranger ex UAV platform

New kid on the blog - the Ranger Ex UAS platform.



So much has happened since the good "old" days with multiplex easystar.

Now the "hobbyworld" of drones got working advanced autopilots and platforms in all kinds of designs to fit all kinds of drone jobs.

The new kid (Ranger ex platform) will soon be ready for buying.

The platform is a 2M wingspan with a LARGE fuselage.

Wings: Strong Epo foamFuselage: molded PVC (like FPVraptor)

Will carry 10000 mAh 4S lipo and still have room for everything. :-)

What do you think about what you see?

Hi All

I have been thinking about a ROLL/TILT for the skywalker platform and I came up with something like this. This design is great for Roll/Tilt stabilization.






Any good ideas for something like this?

Of cause I'm willing to share 3D drawings in what ever filetype needed for milling or 3D printing when and if the thing will be finished.


Inspiration from the skylark uav.

A must have for all DIY people.

3689493046?profile=originalThe new Cube 3D printer is a must have for all DIY people.

Yes! I know you can get a makerbot and yes it's maybe more in the spiret of DIY. But I must say the Cube is awsome easy to use. save your drawings in STL file and boom it's printet. No setup! just more or less PnP.

Price 1299 USD.





The print result is quite strong and with tolerance 0.2 - 0.25mm it's ok for homebrew stuff.


Have a nice Xmas and hope DIYdrones have so much more to come for in the year to come.
