In my opinion, not a good prop for this boat. You can hear the load on the motor. Too much pitch, and therefore, cavitating as well. 🤔

for me it's hard to tell the difference just from the sound of the engine, yes a propeller for hydro I think than for a vhull, it cavitates a lot when starting but when it gets up everything is ok except for the jumps that were due to the small waves created from the previous passage it seems that with this propeller it is very sensitive to these waves, but it seems promising at least on 4s with 6s to much lift maybe different setup on stinger

​@@daiciuapostol79 The rpm seems to drop a lot from cavitating to 'grip'. In combination with your comment that it already destroyed esc's and a motor, I wouldn't use that prop on a V-hull. Only very light running hulls, who can take the prop load. What was the speed on 4S?

@@CozyRC 98 km/h with 6 mm less prop, I have +3mm stinger setup
