 Telemetry names are shared with the dsm2 protocol, and as such, their names are not very appropriate to describe the quantity they represent. Telemetry names are shared with the dsm2 protocol, and as such, their names are not very appropriate to describe the quantity they represent.

An alarm of 2.8 - 3.0 could be used.

 **Additional:** \\ Since the telemetry range is shorter compared to the tx range ( with PA ) , there is no point setting an alarm for quad reception strenght, as the telemetry will probably fail before that level is reached. **Additional:** \\ Since the telemetry range is shorter compared to the tx range ( with PA ) , there is no point setting an alarm for quad reception strenght, as the telemetry will probably fail before that level is reached.
  
 The quadcopter only sends telemetry after a packet is received from the transmitter. This is to avoid on-air clashes when the code hopping becomes unsyncronized. Because of this, the telemetry rate will go down when reception is poor on the quadcopter. The quadcopter only sends telemetry after a packet is received from the transmitter.
