My first EP flight

Past Thursday was the first day that I had an opportunity to try EP plane for the first time. The model airplane was my modified Majestic 30 with Futaba motor FMA-5055KV410 embeded instead of gas motor. Though 4 cell 14,8V Li-Po battery was selected at first, I realized it was not enough voltage to make maneuver and exchaned into 6 cell battery. APC 17-8E prop provided me enough capability to make patterns in the sky. The response is different from the of gas power, some different possibility to proceed into EP world was premonition. Because the center of gravity was not established in Majestic at all, the adjusting procedure was required there, too nose heavy phenomena was observed. Basically, the C/G position must be adjust by moving the heaviest component, battery(for motor and RX and servos) must be moved to posteriory, so this procedure might require the repositioning of rudder and elevator servos backward, it's troublesome and complicated manner?
