The S8R provides the user a choice between a normal 8-channel receiver or a stabilized receiver. There are two stabilization modes (SAS and autolevel) and two aerobatic elements (leg and candle) that can control channels in flight. Autolevel will be especially appreciated by beginners.
The FrSky S6R adds 3-axis stability to your winged aircraft. In addition to stabilizing standard planform aircraft, the receiver can also stabilize flying wings as well as aircraft equipped with V-tails.
