strong prop can take a hit
These are my favorite props for all the 3.5" quads. I know the PID tunes can make a huge difference too, but I am getting little to no prop wash compared to the EMAX and HQ props.
I’m running these on a 4” Apex with 1507 & a throttle limit of 75. My AUW is 447g (session5 and 1100mah 4s.) Take that into consideration when reading this review. Lol. They have great control at lower throttle. They have pretty good punch but coming out of dives I have to give it full throttle to not bottom out. Not unexpected since my settings and weight are what they are. However, I experienced the same thing running 2004’s and 4x2x3’s. I think I feel blade deflection. I don’t quite know if these have the same issue, but willing to guess that they will. If I put my motor output back to 100, the props will spin faster but still probably deflect. Spinning faster will probably lower the durability as well. I mean, they’re only 2” pitch and there’s not all that much meat at the hubs and the tips are thin, like most GF props. So, I like how they fly/feel, but worry about blade deflection and durability. Like other GF props, they still fly pretty well when they are beat up some. Overall, I might like them to be 2.5-3” pitch, and that might be just right for my rig.
Run these on 1407 4000kv. 👍
