These are the Propellers that I'm now using on my main Alien Quad. I've had a number of people asking about them, some of which were surprised that APC had MR Props for, so hence I thought I would share this video. One thing I did forget to mention on this video is they have a very similar shape to Carbon Props used on Multirotors.
The biggest surprise when I opened the first pack was the quality of the moulding and in particular the Prop Adaptors which are way better than the Slow Fly Props we normally get. Also Hub imbalance seems to be far less an issue with these props.
