Prop advice

[BHChieftain]

Running a toysport syncron with flood chamber on a neu 2200kv motor 4S1P. Getting good handling and great speed with x640 prop. Happy with this for my racing prop, but runtimes are a little short and lipos are a bit warm for sport running.

Looking for the next best prop down from here for sport running:

The X640 total pitch is 2.512

Considering either a x637 or x445

x637 total pitch is 2.368
x445 total pitch is 2.478

Any thoughts? When I had a 1500kv motor in here I was running x646 prop, but getting a bit of chine walking with that large of a diameter, so not sure if the 445 diameter would be pushing it...

I run a m445 on the same setup in a df29 and apparition and like them both but chime walk is an issue in the df

Have you considered a prather s215? That would be the perfect balance between the x445 and x637.

Total pitch looks pretty much the same as the X640 I'm running

Settled on an X637 prop-- got one, tried it out, works great.
