Reviews of Blue Bird BMS-385DMAX (4)

  • Rating:

    Application(s): Tricopter-Baby (RCexplorer)

    Comments: Added a feedback wire to the potentiometer and connected it to the RSSI input of the Flight Controller. It's speed and torque is very good but unfortunately it flutters badly no matter the tune or additional hardware used. Should be fine for larger copters but another under 200 mm motor to motor spacing should look elsewhere.

    Application(s): 48" 3D, 60" sloper

    Comments: These are excellent servos. I've had a pair on a NCFM M60 slope flyer which I've had in the air for 62 hours now. I spite of rough conditions (sand, rain, hard landings) these servos function flawlessly.

    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.

    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!
