prop help please

[delta farce]

I have a feigao 540xl 9xl 1898 rpm per volt and a 33" delta force mono, not sure what prop to use....

[revoltrunner]

it depends on how many volts your going to run in it.

4s and seaking 180

[revoltrunner]

if it were mine I would start with a octura x642.

I used to run an M445 on that motor in a 32" boat. Went pretty well.

[delta farce]

I ordered a M445, I started with a X645 which was too much prop...

Stick with the 1.4 pitch props or maybe the Prathers(1.5-pitch) for the mono. I had all kinds of rude behaviour with 1.6 props on my DF 35".
