ivoprop 3 blade for 912ul

[kevmo777]

Got a 70" diameter ultralight prop on 912 80hp. Trying to set the pitch I can't get over 4500rpm with angle adjusted all the way flat. I know they make 2 different ultralight props-how can I tell the difference between them. Not sure if I have a power issue with the 912 or too much prop. Any thoughts? Thanks.

Just confirmed that I have the 35-70 pitch, wondering if I need to cut the blades, or get a 18-52 pitch..... thoughts??
