Propeller selection for Gaart ML2212S 920KV Motor

[St79]

Hello friends, I want to buy a propeller for the ML2212S engine, I wanted to get your suggestions and opinion?
Can you suggest a website where I can buy quality propellers?

First of all, I have one or two questions.

1 - ML2212S recommended propeller is 9443 propellers for 4s. Do you mind if I use apc 9045 , 9060 or T-MOTOR 9.5x4.5? The propeller size decreases by 1 cm but its angle increases. will there be a loss of lift force?

Hi increase of pitch gives more lift but at a cost the motors need to give more torque to spin up so can make motor hotter and can pull more amps through the esc ?, can the motor change prop rpm as fast as needed ? Plastic props are cheap so buy the size you want to test it they work now you want then upgrade to carbon fibre

Thanks, buy 2-3 different sizes of propellers and measure the currents and engine temperature and experience.

That's the best way , everyone flies a little different so props I like you may not like

I suggest this site a lot but when doing custom builds it is really nice for getting the in theory numbers on how changing prop size/pitch will affect things ecalc.ch (no affiliation is just a useful site)

Like you all said too though changing props not generally going to be a big risk just might stress the motors/ESCs a bit more but in my personal experience ESCs more likely to fry out first motors tend to be pretty resilient if they don't get physically knocked or have screw shorting the windings.
