These are a small 5v Lost Model Alarm LMA buzzer device which is driven by Hi-PWM signal & makes a lot of decibel pee-pee-pee piercing noise via an RC trigger point (failsafe setting or switch) to enable you to find your miniQuad after an FPV crash in thick bush. This type requires an RC signal >1500uSec to trigger it and will not function if connected to 5.0v DC alone - its more sophisticated and driven by RC PWM so if you crashed out of range - it can be pre-set to go off - allowing you or a friend to walk straight to it. Alternately you can assign its activation to an RC switch on the Tx - so when you walk closer - you can switch and listen ; get an angle to walk ; which works better for long range recoveries
One LMA with servo RC servo lead
So then ; RC Aux channels would pass thru to pins RC5 and RC6 - see photo at right.
