New propeller for 912ul model iv

[Goodyfab]

Hi guys I have been researching props for my model Iv 1050. I am trying not to make a mistake… I believe I am leaving a bit of performance on the table with the gsc.

im thinking about the ivo but I don’t know which would perform best . ultralight or medium , also trying to figure out exactly what the IFA weighs ( as a system).

im also curious about Luga. Does anyone have a contact ? Curious about cost and how it would perform .

thanks for any help, trying not to start a prop collection.
