If I remember right, the problem with the DS821, was that people had put Loctite on the screw, really bad idea!!!!, I'm sure that I can still find the bulletin from horizon, sure horizon recommend 60-90 planes but a warbird have little ailerons, so the DS821 is plenty strong for a warbird
as for vibration, my corsair and mustang don't that much compare to my little H9 mustang with a saito 100 in it
