Price: $43.70

Description

The Blue Bird BMS-A10S is a great new wide voltage range (WV) tabless servo with amazing torque, speed and precision in a tiny case only 8 mm thick. The S suffix relates to the smooth case as no servo mounting lugs (tabs) fitted, making this servo ideal for gluing straight into wings and tail surfaces for compact, simple mounting. We recommend epoxy glue is used.

With a weight of 7.3 g and a speed of 0.07 sec/60° the Blue Bird BMS-A10S is ideal for DLGs, F3K, F3P, F5J, and all electric racers, small gliders and 3D RC models. Being so thin and lightweight the A10 is also ideal for installation in the tail surfaces of larger models.

With a wide voltage range from 3.7V to 8.4V the BlueBird A10-S works perfectly on 1S and 2S LiPo, and well as 4 and 5 cell NiMH batteries.

Do not buy Blue Bird BMS-A10S WV Servo!!

Servo drives are significantly heated during operation even without load when powered by 5 volts. (about 40-45 gr C) What will happen if they are powered from 8 volts? Most likely, magic smoke will go out of them. Accordingly, they consume significant current, which will lead to a fast discharge of the battery.
I would advise the manufacturer to think about this fact. A site https://www.hyperflight.co.uk/ so far to limit sales of these servos to avoid dissatisfied customers.

BMS101 Hv servo

great little servo, fits into small spaces & packs a punch .I do hope however that they perform better than other blue bird servos I have used in the past ,which for no apparent reason suddenly pack up!

Astounding tiny servos

This is my first foray into the world of DLG. Neil at Hyperflight couldn’t have been more supportive in terms of recommending a suitable glider and these servos. The servos are tiny compared to what I’m used to but beautifully made with a lovely CNC milled case and a great cosmetic finish. They seem to have no discernible slop in the gear train and have a good voltage range. I will be using a 1S LiPo to power them and my Jeti radio with a vario giving me useful telemetry.
