Guess what I found in my stocking this morning? Couldn't wait to do a comparison between the MA and stock screws (both new).
Run time is very difficult to quantify without lab equipment.
Noise is also subjective but seems like the MA props are quieter. I especially noticed the reduction in noise when I accelerated vertically at full power. Non-scientifically speaking, I can still hear the stock props at 350'. the noise from the MA props seems to become very faint at about 250'/275'.
Performance is also subjective depending on what you are doing. I decided to perform a series of "time to climb" tests as a benchmark.
After timing a climb to 400 feet from the same launch point (5 times for each set of props), the result showed that the MA props resulted in a solid 5% improvement in performance over the stock props. Whether or not you can equate the increased climb performance to other activities or not is debatable.
Notes: The MA props seem to be a bit more difficult to install than the stock props. They were tighter on the threads and hence, take more work to get them seated. Mine didn't simply "spin down" like the stock props. I couldn't get 1 of the props to start on the threads at all. Upon inspection, the nut was not fully seated and was aligned at a slight angle. I noticed it was not engaged on one of the tabs all the way. Applying pressure to the top of the nut resulted in a "snap" and resolved the issue.
That's my story and I'm stickin' to it!
