The FlySky GT2B features 3 channel operation, interchangeable hand grips, adjustable steering dual-rate, servo reversing and a rechargeable li-ion battery which eliminates the need for buying expensive AA batteries. The li-ion battery also makes this transmitter much lighter, which gives the user a great feel during use. No more lugging around a heavy transmitter holding 8 x AA batteries!
