Thanks RAYDAR for the vid

Ive been a big fam of Bluebirds and have a few of the smaller ones...150oz. They have performed great. I had 1 go out when I applied a mix beyond the absolute travel...but that was my fault. I should have set the absolute travel first, then applied the mix.

man up & get a real servo

The BLS 3114 and BLS 2209 servos are Manning up to the task! The Futaba 9157's are good but they stall on the elevator of my edge at 6 volts. The 3114 blazes its way to where you want it in any maneuver on my 104 extra! Start stop right now performance. I would tell you at least give em a try!

It is a good servo,nice face and good quality

Good news on Blue Bird customer service. The servos I sent them are back and operating like new. Took 1 month from the time I sent them to be returned good as new at no charge. I just paid shipping to send them 12$ not 27$. One was warranty (BMS 1715) and the other I destroyed the motor pinion by using the A 206 mini as a tail wheel steering servo on a 30%yak 54. Customer service!

did you send them to a service centre in the US or Taiwan?

There are not any US dealers / service that I know of. I sent them directly to Taiwan.

I purchased two BLS-31A for comparison . I ran both on the bench using the servo function on the radio transmitter, no problems, heated up 10f after a hour. The lash measured .010" at 1 1/4", feels like a Hitec 7955. Attempted to measure the torque but my 16# spring scale ran out of travel, I need to borrow a friends 50# digital. I ganged both together and ran them over the entire travel range, could stop anywhere and the current would drop to zero. I could find no reason not to purchase more and use them.

I have Put some hard stress maneuvers on them and the response is lightning fast. No gear wear or slop. Still tight as the day I opened their box. Center perfectly and have a 25 tooth spline just like futaba. I am near completion of a 104 inch extreme flight extra 300 and using the 3114's all around. So far I think they match up pretty close to JR and Futaba quality and performance. At half the cost of high end servos I think these are no brainers for the 3D / High performance arena.

49dimes, can you give an update on the Blue Bird brushless servos? I've been following these and am quite interested. Considering BLS 26A for ailerons in a 120cc Edge.

Electrical Specification (Function Of The Performance)
Torque At 6.0V 21 kg-cm / 292 oz-in
Torque At 7.4V 26.5 kg-cm / 368 oz-in
Speed At 6.0V 0.11 sec / 60°
Speed At 7.4V 0.09 sec / 60°

I have had the bls-31a in my 91" EF extra running on direct 2s lipo, they have filled my expectations over the last year and given me no issues. I have felt confident enough to purchase 9 of the bms-35a for my upcoming 120cc build.

I have been running the Turnigy 620dmg re branded Blue bird servos in my profile for over a year now with great success. Very little slop, fast speed, good centering and great torque. I bought extras in case of issues but have not had one so far. If your looking for a 200 oz/in class servo, these cannot be beat when you factor in a $18 price tag. I had nightmares with the Turnigy re branded Power HD servos but these blue birds have proven to be a great servo at a great price

You said "bms-31a", but I think you meant "bls-31a", brushless, correct? I have the bms-35a coreless and the bms-28a coreless. I don't see a bms-31a on the manufacturers website. I have the bms-35a on the rudder of a 35% Extra and its getting the job done.

Woops corrected the above. To confirm I have the bls-31a (brushless) on the extra and have the bms-35a (coreless) to try on the 120cc build.

Mutt those 620s look like just what I have been looking for to go in a 1.20 sized project I didn't really want to spend a fortune on.
