Your question will appear on the site once someone answers it.
A lot of the same tendencies as the Gemfan Hurricane line are here - very linear throttle response, light weight for tunability, great (but not the best) durability, and ability to maintain balance even after re-bending extremely well.
On more conventional mid-KV setups, I feel like the 51466 from this same line carries a real edge for feel, and the improved efficiency of those setups work best. In true lower KV, or for higher speed obviously the 51499 is the ultimate answer, but even running those same setups these 51433 versions turn it into a solid indoor/proximity variant of the same quad, with a very locked in feel, just no top end speed.
Embarrassingly, the biggest reason these are my favorite among the Hurricane line of props is that the come in Purple... but my purple race setups happen to be running 2650KV/5S or 2150KV 6S, so these work brilliantly.
I can't comment as much on freestyle feel, but for a lot of stereotypical setups (1950KV 2207.5 on 6S, or 2306.5 2722kV on 4S for examples) these are going to work well to make aggressive KV combinations work extremely well and maintain efficiency, although they'll be similarly underwhelming on lower KV setups (1700KV 6S or 2400KV 4S) if you need lots of punch, but again overall efficiency when I tried those was brilliant with long flight times, but it felt like I left too much throttle limit on despite having none active.
FYI I fly DJI FPV with no gopro so my rigs are lighter that you guys w hero's so YMMV
Flo-Rida FPV on youtube if anyone wants to see the juice w ImpulseRC Apex's ...i just superview DJI HD DVR
BUT! On amax 2207.5 2500kv motors on my racing quad they're amazing. Cornering is great, smooth and responsive.
