A technical question which is a bit of a long shot for the answer but here goes. I've replaced a 5.8ghz tx module with a 2.4ghz on the same 5.8ghz pcb inside the transmitter. When plugged into the RC controller software it's still recognising the board as a 5.8ghz. The board for both 2.4 and 5.8 are the same ( both labelled as 2.4ghz) My question is this :- Are the boards flashed with their corresponding frequency ( permanent ) or is there something I need to do ? Thanks.
