We just purchased two Epoch's Spec 2's and have found the run time to be about 7 to 8 minutes before either one starts to glitch or slow. Just wondering if this is the norm. We have recharged about 5 times total. Also what about discharging or running down what little power is left. The adds say the spec 2 has a NI-MH battery and the instructions say NI-CAD. The instructions however are for the spec 1 with a suppliment for the spec 2. In the past I have learned that NI-CADS will build a memorey if not discharged correctly. So any ideas which we have and what do you do. Any aftermarket tires, bodies etc.
