AR637T 6 Channel SAFE and AS3X Telemetry Receiver P-SPMAR637T

Spektrum AR637T 6-Channel Air AS3X Telemetry Receiver (SPMAR637T)
Like its predecessor, the AR637T features built in AS3X Technology, but now pilots can set up and program SAFE Technology to their aircraft. AS3X Technology (3-axis stabilization) works behind the scenes to smooth out the effects of turbulence so you enjoy a sense of stability and precision that makes it feel like you’re flying a much larger, expertly tuned aircraft. SAFE Technology offers an extra level of protection so that RC flying is easier than ever before. When activated, bank and pitch limitations keep you from over-controlling and automatic self-leveling makes recovery from risky or confusing attitudes as simple as releasing the sticks. Programming and set up of AS3X and SAFE is done directly from your Spektrum transmitter* with an easy 3-step forward programming initial setup. To use SAFE and AS3X technology with the AR637T receiver, the receiver needs to be set up with a compatible Spektrum transmitter. With forward programming there is no need for apps or cables to program or make changes while at the flying field.
