Default Need help choosing a lipo and prop for a 50" tiger moth with E-flite Power 25BL and 40amp ESC



I have a beautiful 50" tiger moth with a 40amp ESC and E-flite Power 25BL. I have plenty of 4s 14.8V 3300mah lipos but they throw off my CG and they are a tight fit. Iwant to use my 3s 11.1V 3300mah lipos but I'm not sure about the prop size/pitch. Also, how will it affect my power/flight time??

Any and all help is appreciated!!

A 12x6 seems to be a good match with the EFlite Power 25 on 11.1 volts. You will have to decide if the 12x6 will fit the plane and whether the thrust indicated will provide adequate performance. I've attached a DriveCalc run.
