Hello, it's my first post on DIYdrones.
I plan to build an UAV Plane for photogrammetric purpose.
As I like compute, calculate and plan before build, I try to compile the mains characteristics of the planes frames.
One major char which is not provide by

Read more…I have the power module, but the voltage of the battery keeps going up and down non stop. Every second its different. One second 11 volts, the other 10.6, the other 11.1 and so on. My quad did 2 landings because of low battery when i have set it to 3

I also want to collect photos in RGB of these plots, as the RGB from Rededge is fairly low quality.
