Martcerv posted about these a while ago and I decided to try a set. I had to ream them out to 8mm to fit the motors and some serious balancing was needed but the result was a faster and much more responsive machine. I don't know how much faster I was going in attitude mode but it was definitely faster with more lift when needed. I would have made a quick video but I headed out in between rain so didn't chance the gimbal or camera on the first run. I will post some video soon of two identical runs, one with triblades and one without. So you can see the difference in speed. Check them out.
