Master Airscrew props are good only for stirring paint. Use an APC 'thin electric' or Zoar PJN wood prop, these are FAR more efficient for electric power.
thanks for the input, i've heard lots of good things about XOAR props, but I'm reluctant to buy some until i know if they will fit into a 2" spinner. seems that 13" and up have larger hubs that would be more comfortable in a 2.5" or bigger.
