...has benefits...no imposed adverse yaw forces from (aero) tow lines or engine thrust lines. You want to go right...you shift right...but that creates a left yawing force...which t...Comment on "Efficiency: Perfect pitch UAVs and airboats lead to new propellers (at least some good from UAVs / Drones)"
from my understanding its the length of the prop that creates more thrust from horsepower.the longer the blade the more thrust . but in a trike you are limited by prop arch room so...Comment on "This is how to harvest Xmas trees in a hurry OMG"
