This servo is super for the price..very fast,very precision centering very strong and well made. Japanese coreless motor with HVoltage is perfect solution for strong application. Blue Bird is a very good factory that made in Taiwan a very best compromise from quality and price!!! Now i have more flight with it and it is perfect. I have other BBird servo BLS 31A and BLS 2112 and I'm very satisfated from it for high precision of centering and resolution,this is at the same of other brushless famous brand i have Futaba BLS,Savox SB.Now i test the durability for have a final review.

I've been really impressed with BlueBird servo's, I use 1 of these for each eleveator half of my 35pcnt Su-26, and it's big brother for Rudder. The centering, response, and lack of slop is amazing for a servo this price. Current draw is minimal as well, torque is as advertises, and you will not be lacking in speed.

I'd gladly recommend this servo to anyone.

Very good torque and amazing speed for the price. I used 2 of them in a plane but each one like 1oz heavier than regular standard servos (it is around 79 grams not 74).

Excellent servo for its price. Using it on my mugen mbx6e with a high voltage setup for a few months now. Got into a serious head on collision with a short course truck that was going the wrong way... what was that @ driver thinking???... suffered a broken front arm, bent shock shaft, dented shock body but the servo survived... just bought another one. Well done hobbyking!!

Hello, I put this servo on Losi 8ight-T Truggy and I am quite happy with the speed and torque. The gearing is a little louder than my first BMS-35A bought 1 yeat ago... I put more grease in it and I use plastidip against water. I have to wait for durability...

I post a video on youtube, you can find it easily with tags.
Regard and thanks to hobbyking
