Review by: DickReplacement for BMS-106HV
Had a Bluebird BMS-106HV fail in my AHI wing so I bought a couple of these as a straight replacement. They fit perfectly.
Ordered at 14:30 hrs and received them first thing the next day. Thanks Neil for your excellent service.
Review by: Nuno Duartenot as aspected.
the servo looks strong as expected but makes continuous noise. even at the neutral point. I hope it lasts long enough
Review by: anick
bought for a Snipe RES glider, for the "S", very powerful. probably on 1s will be used.
Review by: AnonymousGood servo for micro helis
Great cyclic servos for micro helis, can also be used on the tail if run on 8v. They will fit an Oxy2 but you need to sand about 0.3mm off the end of the lower mounting tab and make sure it's pushed up against the upper bearing block when installed so the end of the tab won't brush the screws on the maingear assembly. These servos run at 250hz maximum so make sure you change the servo frequency in the FBL controller setup before plugging them in.
