Hello
I tested out my QC25 in a light GA aircraft.
It is nothing like the A20.
The A20 is twice the price of a QC25+uflymike but in my opinion it is worth it, as an investment.
However, congrats on uFlymike for making such a product work, because a simple jack adapter did not allow me to hear the radio with the QC25, when plugged into the aircraft through this adapter.
