FAN on Speed Passion Reventon Pro V1

[spiboom85]

Hi Chaps

Iv just bought the Speed Passion Reventon Pro V1.1 ESC Comp V3.0-7.5R Combo very happy with the product was very tight to fit into my tm2 v1 but got there

Now a quick question when I turn everything on the Fan that sits on top of the esc does not come on Now iv contacted modelsport, they think it will kick in when the esc reaches a certain temperature

just wanted to no is this the case' as I don't want to run / over heat the buggy

Thanks Steve
