The Blue Bird BMS-101AMG is a tiny metal gear servo from Blue Bird wih an analogue amplifier, as preferred by some for lower current draw and the relaibility that comes from using well proven technology. This servo is strong, powerful and has a very tight geartrain with little or no free play. Featuring low weight, a 7.6 mm thin case and one kg-cm or torque this is an excellent servo for DLG / HLG / F3K / F3P / 3D EP RC models.

The 7.6 mm body thinness ensures the Blue Bird BMS-101AMG will fit in very thin wings, making it a great servo for 1m discus launched gliders and small slope soarers. Its light weight, high speed and great precision makes it well suited for F3P and other small aerobatic/3D indoor and outdoor RC models.

The BB BMS101 AMG is supplied with four output arms, mounting screws, optional mounting tape, and a fun sticker set. The large arm is 5 cm diameter (2.5 cm largest hole radius) making it excellent for F3P aileron control.

The Blue Bird BMS10AMG is in many ways similar to the Ripmax SD100, and is a good alternative to this servo for those using NiMH batteries or 1S LiPo batteries. Its main benefits over the SD100 and the Dymond D47 are its metal geartrain giving it greater toughness. For applications a 2S LiPo battery we recommend the HV version of this servo: Blue Bird BMS-101HV. Also see the disgital version of this servo, the Blue Bird BMS-101DMG.

Blue Bird BMS-101AMG Servo

really good quality - definitely worth the small premium

 Review by:

Small, light but not perfect

Very neat and tidy little servos. Bought 4 for my Hawk DLG but finding they are not centring crisply enough for the fine tuning of control surfaces need for a lightweight model. Also the servo wire exit from the body is very fragile on two of the four, where the wire doesn't extend far enough inside to cope with a bit of "raunging". Didn't realise until I'd cut off the mounting tabs so can't return. They are working but leaving me a little apprehensive!

Purchased three of them for my Malibu Pro. Servos are very compact yet powerful and fast. Very good servos at a competitive price. Customer service by Hyperflight is excellent.

Blaster 2e servos

These are a perfect replacement servo for the vertical and horizontal stab. Slightly smaller than the recommended servos. As per usual Hyperflight have been excellent with advice and extremely quick delivery and ordering service.

Fills the bill

I ordered those for a Vladimir ELF build, and so far - after about 10 hours of flying in freezing weather conditions - they've performed flawlessly.

The choice of the analogue, non-HV version of this servo was deliberate, as I'm running the ELF electronics directly / unregulated from a small 250mAh 1S LIPO.

I stop flying after about 2 hours, when the LIPO is down to about 3.80-3.85V (safe storage voltage)

That's pretty efficient, especially considering the low temperatures.

KILLER like servo

Outstanding servo! Using for ailerons on my F3K model. Will be ordering more. Lightning speed and great torque/centering on 1S lipo. VERY satisfied with it. 😀😀😀

Great service for the price

BMS-101AMG 1/6NG

I bought six in total so far, but one was defective.
Although the operation with no load was good, I was bogged down by the torque of the torsion bar.

Blue Bird BMS-101*

Blue Bird 101 * - excellent servo, especially for small DLG!

BlueBird Servos

The Bluebird 101amg servos I ordered from Neil arrived safely and well packaged. These servos are EXTREMELY small and light weight. I haven't powered them up yet but they look like they are just the ticket for my HK V2 DLG aileron position. I can't wait to see how they work. NICE PRODUCT!
