Nope - they should not be used on the Mavic 2 Pro!
The MAS 'Stealth' prop's have a diameter of 8.3" (211mm) and a pitch of 4.4" (112mm).
Stock DJI Prop's for the Mavic 2 Pro series, have a diameter of 8.7" (220mm) and a pitch of 4.3" (109mm).
They will work, but there will be absolutely no advantage in using them - and the GAIN settings used to stabilise the Mavic will be out of kilter (i.e. you'll probably need to do some major tuning to get the craft stable for it to use the prop's). Master Airscrew have been saying for a while, that they are producing a prop' for the Mavic 2 Pro - but it's not there yet. The Mav 2 prop's are a radical redesign by DJI, so it could be that MAS can't get a great enough improvement to make it worth-while [??]. They do seem to take pride in producing a product that is an improvement on the stock product it replaces.
