When walking up sizes of props, do most of the experienced racers out there walk up their props via total pitch? If all variables are equal (boat weight, C rating, esc rating, running gear); how does amp draw increase between 2 and 3 blade? If I had an ABC 1914-10-50(2) and an ABC 1914-15-60(3), which would be worse in case of amp draw? I assume the rake difference is directly related to the number of blades, but both these props have the same total pitch (2.66). Or, is it just a matter of corner handling? Application example would be for a GP400 hydro. Any guidance would be appreciated.
