Hi all,i have reading up quite abit lately abt radio equipment, but i still have no idea why an r/c heli needs a 9 channels Tx 95% of the ppl i see from the local airfield has a 9 channel tx for their heli, from my limited knowledge is it true that all u need is a min of 6 channels to fly that 3D bird ? so if tat's the case where does the extra 3 channels go to ?
