ESC fluid?

[Rich]

bad soldering
not fully charged battery
failed to calibrate throttle first run
timing too high
1/4 throttle had boat wet.. lotsa draw then
many reason you can sh ite an esc first time out.

why waste 80 on SK120 when a few more coin gets the T180.. far better choice.

going for 1/4 throttle could do it, but drwayne is right it could be any of those reasons, check for binding in your system.
