Default power cutting out

Hi, I got in to this hobby for my son and have many rc boats. I have a few voracity boats and one seems to be over heating and will only run for 40% of the battery life after 3 years. The ESC and motor are running hot. and when I open the canopy up the esc is blinking red. I was told that the cooling lines could be clogged so I blew them out with my compressor. Any one know what the problem is ... The boat ran fast and never heated up in the past.

Cool

Common reasons for overheating include:

- prop too big
- motor shot - overheated, bearing seized, shorted windings, rusted
- ESC timing set wrong
- excessive time spent at part throttle
- driveline friction - when was it last lubricated and with what?
- insufficient gap between drive dog and strut
- hot pond water - doesn’t cool as well as cold water

If the battery quits after just 40% then the battery is probably shot. LiPo packs should be stored at 50% charge and in cool conditions, otherwise they lose capacity. Plus, cheap packs especially only last so many charge/discharge cycles, they are expendable items. Higher quality packs perform better and last longer....but they cost more. Ditto for NiMH except they should be stored at lower voltage.
