I've made the decision to go with this motor in my Maule. I need to order some props for it at the same time. Towerhobbies says not to use electric props, I was looking at the Xoar they sell and they have 2 types of wood props, "PJN" & "PJE". Which ones should be used with the Rimfire 65cc motor?

IMO, there absolutely NO reason to not use "electric" props on electric planes!! They are lighter, usually draw a little less current, spin a little faster and create somewhat more thrust.
The Zoar "electric" props I've used are just as tough as any other wood prop IMO.
From my point of view< Towers is sucking its own air!! windwolf

I use a electric 26/12 xoar with that motor in my 33% suhkoi on a 12 cell 6500mah batts with unreal vertical acceleration! 2 years with that prop and no failures.
