Following on from the hugely popular P-51 Mustang this is the new Eachine F4U Corsair. No assembly required other than attaching the fixed landing gear if you feel so inclined. Comes with 3 batteries. Charge them up with the provided USB charger, put 4 AA batteries in the transmitter and go fly. Has 3 flight modes. Beginner, Midd and Expert. I flew on Midd most of the time and it was great fun especially in the warm breeze.
