Fun Bat and OS CV 15-A Prop ???
I'm playing around with a 15-size combat plane (J&C Hobbies Fun Bat).
Most fly this bird with a Magnum XL 15 on a 7x4 prop.
I'm running with an OS CV 15-A and an 8x4 prop.
Anyone out there doing something similar and could you give me an idea of an optimum prop size for this combination.
