Could somebody please give me advice on what prop to use on a Wayfarer Biplane of 54" wingspan. I am fitting a new SC70 4 stroke. I am new to this and have been told the bigger the prop the better for both take off and landing and also to help keep the speed down on approaches etc and I am going to need all the help I can get lol.

Most 70 size four strokes use a 13x6 or 14x4 for sport or fun fly flying.

Howdy,

My wayfarer is equipped with an old Enya 60II which produces a listed 1.1hp This engine is performing well in the plane using an 11/7 prop. My wayfarer is a scratch built from the original RCM plans from 1972.
