nope, same problem even when armed. I nearly avoided a crash yesterday when trying to make it fly correctly, the altitude regulation was not done at all. When trying to tilt a little the drone to the rigth it jumped into the air suddenly, and the altitude shown on the HUD (tower on android) was still zero.
I’m using Navio+. The 3.3 version is when using your ArduCopter-quad executable. The 3.4dev is when using the arducopter-quad from the build/navio directory from the source.
I assume the parameters used are the same since they belong to the same directory whether I use the 3.3 version executable or the 3.4dev one. am I wrong ?
