OS FS 70 Surpass II Best Prop


Can anyone share their experience with the best prop size for the OS FS 70 Surpass II. The book indicates props in the 12-6 to 12-8 for stunt planes but this seems small to me. The motor is on a Revolver 46 to 55 with a 59in span and weight of 7lbs.
Appreciate any help

The engine is quite torquey and forgiving with different prop sizes. I've used 12 x 8 and 13 x 8 Master Airscrew props with great results on a Goldberg Cub on floats.
