RE: Propellers
I have been piloting at the SAE competitions in Fort Worth Texas since 2007.... In the past the common engine was the OS 61 FX, so one would have to presume it will be the OS 65 in the future. One team I flew for was using a Bolly 13x4 if I remember right, and gave it to me in appreciation. (did not work real well on my 60 size stick though [:'(]) It was carbon fiber, though most teams use the apc.
