Ro,
For 3D acrobatics, I suggest you to use a 13X4W APC for that FS 70 and if you can get a Tru Turn spinner for wide blades, your plane will look great.
Now, if you can´t get the APC 13X4W propeller, get a 13X6 APC, Master Airscrew or the brand you prefer.
I´m sure you will enjoy the flight of your Kyosho´s Edge 540 with this set-up.

Best regards.
