Hi
ive just bought a second hand Swallow EX90 pattern plane and plan to place a YS FZ110s engine into it.
im currently stuck on what prop to use with this combination. Also what mix of nitro should I be using?
thanks in advance.
cheers
Jamie

I would say the 15-10 to 16-8 size and 30% YS likes the higher nitro content, but im sure it will run just fine on the 10 to 15 % range

I ran a 15x10 APC Prop on mine and ran it on Power Master YS20/20 Fuel.
