We recommend the Spektrum 2200mAh 14.8V 4S 30C Smart Li-Po battery
(SPMX22004S30). Refer to the Optional Parts List for other recommended
batteries. If using a battery other than those listed, the battery should be within
the range of capacity, dimensions and weight of the Spektrum Li-Po battery
packs to fit in the fuselage. Be sure the model balances at the recommended CG.

6.Connect the battery to the ESC (the ESC is now armed).
• The ESC will sound tones corresponding to the battery cell count (refer to
step 6 of the binding instructions for more information).
