Very nice! may have to try this as i fly the 727 almost exclusively for FedexVAC, seeing the new transponder made me think for those that want an updated VC (or for me the start of one) how impossible would it be to change the tone of that transponder to boeing gray then replace the radios with the new digital ones from say the 767 or T7 and change those to the Boeing Gray panel? Just so the tan doesnt look out of place. ::) :-?
