Somehow, my FLAP switch has broken on my DX7. No drops or bangs that I recall; I went to fly one day and it was just missing.
I contacted Horizon and talked to my LHS - they both say I need to send the Tx in to Horizon for repair. The thought of being grounded for weeks while I wait for my Tx is nigh on intolerable.
I know I can find a replacement switch somewhere, surely. How risky/dangerous/difficult/tricky is it to pull this Tx apart and replace a switch? I am not at all an engineer, but I've soldered a little bit (battery and ESC connectors, etc.)
I certainly don't want to make things worse, but I also don't want to be without my radio for weeks if I can help it (I fly every day.)
