Default Prop difference

I need a prop for my 2800-2200kv and 2200-1000kv brushless. But there are two versions:

And this one:https://www.motionrc.eu/products/apc...lack-lpb08080e
what does “slow flyer” means?

Slow Fly props are crap !!

They are thin wide blade props usually in nylon that flex a lot. You definitely do not want to use on a high KV motor. I stopped using them om low KV motors as they lack 'punch' when throttle opened .... you can hear the WOMP of the blade flexing.

The 2200KV motor is most likely a 6x4 E prop ...... APC or similar.

The 1100KV probably in the 8" and up range.

You need a Wattmeter to test and decide what is best prop along with thrust test using a simple fishermans scale.

Okay. I’ll go with non slow fly prop in the scale you suggest. Hook up my wattmeter too.
Thank’s

To be fair a slow fly prop "does what is says on the tin". It more efficient at the low power levels likely with a slow flying plane.
