do you know aprox flight time the bcpp would get on a 2200mAh 3 cell?
It all depends on how hard your flying, if your just learning (hovering around) I would say you will probably get around 15 to 20 minutes of flight time (but that's just a guess).
should i take breaks(no pun intended) in between flights?
Personally myself I would take a 10 or 15 minute break between flights to let the motor cool down a little. If your just learning, you shouldn't have a problem with your motor getting real hot anyway, they only get really hot if your working the heli hard (3D flying)
One thing to remember is, make sure you let your battery cool down before you recharge it
