UAV photomapping in winter

Hi all,
this is our latest compilation documenting flying civilian UAV during the wintertime.
There is a closer overviev of Pteryx components recently published:
pteryx.eu/​_documents/​pteryx-components-assembly.pdf (20MB!)
Key acheivement was extending flight endurance up to 2h WITH camera and parachute onboard, as in snowy conditions you typically can fly only once every few hours. The snow gets into all photo equipment even through the smallest mounting hole, therefore no simple camera cover is enough. You have to fly once and then clean up, charge and de-fog the camera. Flight time and necessity of keeping light weight of the UAV becomes the limiting factor.
Landings are often on frozen, hard soil.
The snow slowly melts to water and flows all around the fuselage, in places usually not accesible by rainfall.
You can change a mission without connecting a laptop - a huge bonus on a frozen field.

Therefore, fly with confidence using Pteryx.

Congratulations great job, i like this desing i wanna buy.

AND THE FINAL QUESTION, what type of motor you used, this is a turnigy, or scorpion, and few kv....rpm/volt

[krbosak]

@catfcatf This is an outrunner of a brand company.

We are not publishing KV or other stuff for the following reasons:

-it looks to be the least problematic element, it operates at very small load in flight

-replacing it would mean the platform has encountered severe damage, so it needs retuning

-selecting a prop and motor can be variable if mfg quality would worsen

-the selection of prop and motor took an effort

-this is not a TOP secret but we do not communicate it to non-customers
