I just bought one of these servos and have not seen many if any failures on this servo. Application is pull pull on my elevator for my DP ultimate. The airplane flies along and suddenly would glitch, the airplane would pitch down and then fly fine, and do it a few times as well. Luckily none occured during landing, but all the times it was straight and level flight. Have you seen this happen before Mike?? I replaced rx, xtals, y harnesses, so i think it may be the servo. I cant seem to duplicate it on the ground, the airplane range checks about 130ft plus with the antenna collapsed. The atv is 140%, but i havent seen an ATV prob with this servo before. THe radio system is a futaba 9cap with a r127df rx. Let me know. I would like to get this servo replaced if it is in fact the problem. I will go try it in a different plane to see if I can replicate the problem. Thanks Mike.
