Not if you have an engine with enough power to turn a 3 blade prop of the diameter and pitch that will net the output that you are needing. The more blades on the prop, the less thrust it will provide compared to a 2 blade prop. I cannot tell you why, but I know it is true. I fly a 15x11 4 blade on a 1.60DZ that power an 11 pound plane. It only works because the engine has power to spare to turn the prop.
