Hi all finally got my 32'' Wildthing monohull finished set-up with a Leopard 3674 1900kv motor turning a x637 prop 2 Turnigy 4s 5000 mah 40c lipo's connected in 2p giving me 10000 mah and my trusted 6 year old 120 amp Castle Hydra esc .I ran the boat for about 10 seconds then it suddenly stops and it sounded like a fire cracker had exploded inside the boat upon un taping the hatch i noticed my esc had fried leaving a black residue all over the inside off boat. I have been using the the same esc motor and prop combo for a long time in a outrigger with no problem. What did i do wrong with the mono set-up. Regards Andris Golts.
