[Pråmskepparn]

SO im building a small 40 centimetre (around 18 inch) Mono, with said motor, but i have no clue what propeller to use? Might 30-35 mm be good?

Are you using a 1/8 flex cable? The 32mm backcut props work very well with the smaller,high kv brushless motors.You can find them here in the misc prop section
