Our engineer has tested as per your instruction; the problem is better but did not succeed to the normal workable function. Mr. Vanchai has also followed up the AP-709 status and begins getting dissatisfied with your neglect AP-709 solution support. He has granted to share the airplane cost half/half to visit helping us solve the problem now. If you needs any test outcome, please trace from Mr. Narit in this loop to see the development.
By the way, five units ST-404 have reached, unloaded and unpacked in our office now. There are found some scar, dirt, stain unevenly painting on your metal sheet fabric surface skin and not sure how your quality control team would have accepted them pass out until our noticeable here. Our stock colleague has taken some photo shots and kindly find theirs in our attachment for reference.
