SIG 4 STAR/ OS 01 SURPASS-WHAT PROPS

Just purchased a used OS 91 FS Surpass and plan on putting it on a SIG 4 Star 60. What would be the best size prop for sport flying, aerobatics, and for slooow landings ??? I am sure these choices will require different size props ??? Any help will be appreciated. This is my first 4 stroke!!!

I have that combination - use an apc 14x6 prop. You will like how it flies - good power and can fly very slow as well.

I agree with delman. Try the 14x6 first, but all 14x6's are not the same so try several brands but make sure you try the APC brand.

I have a Magnum 91 FS on mine, and a 14x6 K series Master Airscrew does the job. Lots of punch at low speeds, about 55 mph top, and very easy landings.
