I have a like new (new 5/4/2010) Hydra 240A esc with new Hobbywing 3a ubec. The ubec is sealed up. Nothing is wrong with internal bec. Castle just recommends disconnecting bec by removing red radio wire form plug above 4s. The wire can be replace by removing shrink wrap on wire and push wire back in plug. I bought this esc in a boat off swap shop. The previous owner said he ran it twice. I have invoice from castle stating it is new on 5-4-2010. I test benched the esc and all work fine. 5.5mm plugs on motor leads and 8mm on batts leads.
