Hi all, thinking of getting regular Turnigy batteries, not Nanos' for my T-rex 450 Sport, just put the combo kit together; which would you recommend? The 25c or the 30c, only couple dollars different at HK, just learning to hover as soon as the weather breaks in PA. Don't want to get a lot in batteries, till skills level goes up. Thanks!! in advance for your advise and help. Enjoy the all threads! Keep up the good work! Kenny G.
