Two questions really:

1. Will the low noise propellers for the Phantom 4 fit and work on a Phantom 3?
2. Are the low noise propellers actually quieter than the regular propellers? Even if its a little bit.

Thanks!

P4 props are not compatible with the P3.

Hi there, thank you reaching out. Unfortunately, Phantom 4 accessories is not interchangeable with the Phantom 3 series.
