Prop design priority list:
#1 Response
#2 Speed
#3 Efficiency
#4 Durability

This prop was designed to balance speed and response. Compared to the F3 prop, it literally trades half the responsiveness for maybe ~20% more speed/power. The durability of this prop is very similar to the F3 and again is not going to be as durable as something like the 51433 or any other blade that weighs more than 3.5g. Don't mind the pitch spec as it's not very helpful in describing a props performance; this prop is faster than the HW S4.

What we recommend for optimal operation:

  • ~2306 or comparable motor weighing ~29-35g
  • ~1800-1880kv - 6S
  • Under 720g AUW (including battery and GoPro) - lower is better

Extended use case:

This prop is not recommended for the sub 350g 5" class. Use the S3 blade. If your quad is ~750g AUW and you're running more than ~1700kv. It'll cap out the prop and it'll start fluttering.
