I've own my P3P for about 3 weeks now with almost 200k ft and 7 hours flying time. First thing is it seems weird if I fly straight up to 400ft I get weak RC signal at only 400ft. If it's straight over my head is it my iPad blocking my antenna? Seems weird at just 400ft. Second I'm surprised at how inaccurate RTH seems to be. Seems like it's anywhere around 10-20feet from home point. What's up with that? Seems pretty consistently inconsistent. Other than those two items, occasional compass errors, seems to work great. I love this thing.
