The Luma 30 is best suited to a 6S setup, there's no reason why you cant build it with 4s parts however you can expect some trade offs in flight time, overall performance and thrust.

Below is a listing of the core parts we recommend for your build, The radio reciever is really up to you, any Immortal-T style antenna works with our standard mounts.
