I know his house is 40yo....but I don't think he's gonna have to deal with iron pipes with lead solder joints....thank goodness. He might have to fight with the rusty floor studs (gotta hate that).

Got a problem. I ordered a 40a ESC, and a UBEC for my 450. Been having probs with the Dynam 30a ESC getting hot and kicking out. Battery stays decient, motor isn't getting very warm compared to the ESC. I did a test by unplugging all servos to ensure they weren't causing a large power draw, the ESC still got hot......I'm thinking bad ESC. Tested with two different motors with the same results so I don't suspect motors. I know Dynam isn't the best in the world and my old Copter X ESC was way better than the Dynam. I think I bought a decient 40a ESC( HobbyWing Pentium Brushless ESC 40A-OPTO) UBEC is (1 x 3A 5V/6V Switch-Mode UBEC (UBEC56))....I hope this clears the ESC heat problem, what do you think?
