Description

The Blue Bird BMS-21HV is a very nice mid sized servo for electric planes, 3D RC aerobats, and gliders. With a torque of 4.3 kg.cm at 0.13 sec/60° this servo is has a lot of torque and a rasonable speed, considering its small size and 15 g weight. With a very narrow 2 µs dead band/resolution and a tight geartrain without free play this servo will give excellent control of the model.

This is a mid to high voltage servo, meaning it will work fine on a 4 cell NiMH battery, a 5V BEC output, or a 2S LiPo receiver battery.

My first impressions are that the servos are well made & work well, installed in a 3.5 scale glider, unflown at the moment.
