Default What size?

Hello everyone,

I'm building a big foam delta, and I'm a little confused with prop size. I'll be using my Hacker C50-9XL (3.7:1) with a 90 Amp esc and a 5s4p 8 Ah battery. I have no idea what kind of prop size to try with this setup. Any advice? Thanks.

I calc 8880 RPM, so one of my favorite props might do it. Master Airscrew 16 x 10 3-blade. You could also go with an 18x12 or 18x14 pattern prop.

thanks for the input. i just tried an 18x12 cut down to 13'' diameter. this setup draws around 65 amps. i'll be trying your 3-blade recommendation
