spectrum reciver + speed passion fan

[frazerstrutt]

i have a sr300 receiver and speed passion esc in my b4 and want to put a fan on the esc but plugged straight in on the esc it will not take the voltage of my 2s saddle lipo as the fan takes upto 7.2v if i plug it into the aux port on my receiver what voltage would it put into the fan would it regulate it at less than 7.2v thanks frazer

just didnt want to blow my fan up haha
