This is an old German bunker from WW2 fall on the beach at Sainte-marguerite-sur-mer, france. The fire services took down the blockhouse in 1995 because of safety concerns linked to cliff erosion.

If you want to know more about this blockhouse and the cliff :

It’s always the same setup, our little quad works very well for automatic flights

Config :

Quadricopter flameweel frame (X450)

ESC 30A simonK

Motors Sunysky X2212 980 kv prop : 10*5

RC T9X open9X - frsky 2.4ghz module

APM2 with GPS and compass onboard

Arducopter 3.1 RC5

Lipo 4S 3000mha

Video link : 200mw 5.8 ghz

Camera S100 with CHDK

Mobius camera with Sunnex lens (pictures from Mobius will not be used due to excessive rolling shutter)

Ground station with Asus 1005HA, 3DR 433mhz telemetry and extra deported 433mhz antenna


Total flight time : 3min40

Automatic flight : 3min

65 good aerial pictures from S100 and 20 ground photos from Lumix G3 are used to compose the model.

Short version, only results :

Here you can see 3D model on Sketchfab, if it appears black, juste wait for texture :

Here you can download logs from APM2 and kmz flight path :


Flight path :


Green : Auto mode

Red and grey : Stabilize (manual) mode

Yellow : Alt Hold

Orange and blue : Loiter


Garry, if you want to fly over the model with GEFS, just download this KMZ (it could take some time to load into GE) :

wow so impressive, great work!

I just noticed I can fly around it in GEFS whoop whoop ;-) If you have placed it on Google Earth it should automatically be there in GEFS.

Were Building a Huge Guide on how to do this with CAD Software on! :)  The guide should be finished by the time I get back from vacation 2/14/14

@Joshua, does this tutorial will talk about 3D photomodeling or uses for models ?

Comment by Joshua Johnson on February 2, 2014 at 4:04am

@Sylvain, Both!  We are focusing mainly on a guide and dedicated forum that will allow for someone with Zero knowledge in this stuff to be able to go step by step to accomplish this with their own work.

Comment by Joshua Johnson on February 2, 2014 at 4:04am

Mostly 3D Photo Modeling though

Comment by Sylvain on February 2, 2014 at 4:21am

@ Gary, paraglider is the better aircraft for this place !
