  • Rating:

    5 out of 5

    Application(s):

    Installed 4 into a PA Extra MX, one on each control surface.

    Comments:

    The servos are excellent. Very strong, very fast and perfect centering! The digital "whine" may be a little loud, but the performance more than makes up for it. I have flown with them for a few months with no problems at all. Recommended!

    Application(s):

    Rudder, ailerons & elevator for a RC airplane

    Comments:

    These servos were found to flutter wildly about center when used with a Spektrum transmitter (DX7) and Spektrum receivers (AR6110e park flyer and AR500 full range). Power supplies were DC battery, Phoenix 35 ESC, and Turnigy 60 ESC. No combination of the above had any effect on moderating this behaviour. Release of a fully deflected elevator caused fluttering of not only the elevator but the rudder, as well. This model had never been flown. The motor was not running in these test. Replacement of these BMS-385DMAX servos by HiTec & Hobbico digital servos eliminated the problem. Neither Blue Bird models nor BPHobbies would respond to my complaints.
