AeroXcraft X50 Black Aluminum Arm for DJI F450, F550, TBS Discovery

High quality, really high quality frame arms. All they claim is true, they are super light, super strong, and will keep your motors running cool, really cool actually. Well worth the 80 bucks(for 4 arms). I wasnt sure about this buy at first, but the performance you will get from your quad after you install these, is great. The esc velcros are a pretty good thing to have for sure. Great product overall.

Love my new upgrade, it feels lighter and stronger

High Quality product
