This video includes the first test run of my Aeromarine Predator 21 running on 5s. The electric setup installed includes 36x60mm 1500kv inrunner motor from my old BlackJack 26, a 120a Turnigy Marine v2 esc, Turnigy 4000mah 4s 40-50c LiPo, and an Octura X442 detounged, sharpened, balanced and polished. This run was after modifying the hatch cover but water is still getting in. Will need to work on it some more to get it water tight.
