Hi everyone. I'm working on a college design project, and it the plane we're building may require a large size pusher props for an electric motor. Specifically, props that are 20" and larger for large brushless motors. Where can I go to look for these, i.e. what companies make pusher props of this size? I've looked at Master Airscew, Zinger, and APC, but was wondering if there are some other companies that I don't know about. Thanks in advance for any help/links! [sm=shades_smile.gif]
