The reason propguards makes sense to me is that in every test of the APAS 3 obstacle avoiding, they say this actually sortof work now, but after a while it inevitably crashes into a tree. Id like to try what others have done and make a bikevideo with tracking mode. My thought was, with propguards the inevitable crash would be less severe and expensive. What are your reasons for dismissing the propguards? Do they worsen manouverability and batterytime to much? Are they not effective and helpful in a crash? Are you never even close to crashing because you are so careful and good flyers?
