I just made some repairs and I'm ready to take my Mountain Models Magpie out again, but I realized I'm out of props. The one on there was bent at the center point on both ends and I was able to bend it back so that it visibly looks fine. I'm sure it's not perfect, but it looks good. Is it still ok to use this prop? Also, what's the cheapest place to buy new props? I've heard a lot about prop savers too, but I'm still not sure how they work. Could someone give a quick explanation? Thanks in advance for the help!
