OS91-4 to eflite Power 110
Hi All,
My 12lbs Norseman with floats was powered with an OS91-4 (13-9 prop) by the previous owner. I have an eflite Power 110 drive with 100amp controller and 9S 5000 batteries. Max power is required when taking off from the water at about 25mph. How can I compare available power from that 91 at 25mph?
eCalc says the Power 110 has available thrust at 25mph of 221.8 oz.
