I've got about 10 hours on my P3A. Had only one mishap where on take off a prop came up so it tipped and skid a couple feet on the pavement and then stopped in the grass. Virtually no damage to even all the props. Just a few knicks here and there. Since then I noticed one flight that I see only one prop in the top of the video under heavy acceleration and sustained high speed. So it's almost as if the thing isn't flying completely level but it flies straight as far as I can tell. Suppose I need to do more testing with spare props, etc. What's the most likely cause(s) typically for this type of issue?
