A guy reported here on rctech that there was an epidemy of BL motors failures at his track ( was it 0r8ital orSyndr0me? dunno)
If I remember well the epidemy was tracked down to the Pelletier effect coolers used by everyone, which apparently caused condensation inside the can and maybe even a kind of thermic shock, causing the failures. The guys stopped using the Pelletiers and the failures stopped. But that was at the time of pre-SPX speedos, with huges rollouts so I don't know what it would be now.
A very good guy at my track uses one but just 5 minutes before racing, just to delay the smothering of the motor a 4'30. He says he starts with a cool motor, but not quite cold. No problem yet.
