The AXI 2204/54 CAN'T run on 3-cells without a LOT of throttle management. You run it on 2-cell 340 packs. Mine should be showing up today. I have it kitted out with a 7 gram Berg RX, 6 gram phoenix 10, 3.5 grams servos... should be the heat. I'm putting the gear in a Superstar without landing gear... the 5.2-5.5 oz planes all had gear and heavier servos. Mine should be around 5 oz flat!
