Hi:
Here you have another pictures for your eye-catch, the 727 by Jet-X is a very nice option but Gemini is greater, is not a big difference between both brands. Just some other attachments and jewelry on the Gemini version. But if you want variety Jet-X is the option.
As for these Mexicana's 727 fleet, they are still some out there but the most difficult to find these days are the next 3 models (Mexicana fleet is a total of 8):
XA-MEE Temoaya (green tail), impossible to find sold out everywhere
XA-MEJ Yacatecutli (beige/blue tail)
XA-MED Saltilfe (red tail) this one should be named Saltillo
Cell phone photos (forgive the quality please)
Jet-X has great details and I love all my Mexicana fleet, the next week hope to complete my collection finally. These months were heaven for mexican collectors but a nightmare to our wallets.
Hope this helps to you.
Greetings
