  • 3 blade prop

    Building the 61" Nexa Banshee with the recommend electric motor 5030-400kV. It calls for a 14x8 up to 17x7, 2 blade prop. Motion recommends the 15x8 2 blade. Is there a way, besides trial and error, to find out what 3 blade prop that I can use? Thanks.

    There is an excellent prop power calculator called eCalc which is only $6/yr subscription.
    One of the best 2 beer buys you can get yourself for this hobby.
