A question about the push pull setup?. If i were to do this, wouldthe second prop(pusher) need to be a larger pitch due to the incoming air allready being accelerated? ie. Say the air is accelerated to 100m/s by the first prop and it enters the second prop with a velocity of 80m/s should i use a larger pitch prop to accelerate it another 100m/s? Would using the same pitch prop let the second engine over rev?
