They carries Li-ion, charger and motors.
Order from GWS over approx. HK$1000, free shipping for electronic components
Goods from Align is cheaper but you need to pay for shipping charge. For example, a 6 channels receiver will cost you HK$130, brushless motors NT$1100, ESC for brushless motor ranging from NT$900 to NT$1500. Please check the price at their site. But Align accepts cash or wire-transfer only. I also want to buy the receiver from them too.
