Small update, servo has been running great no issues. Fast, holds its position very well, I currently have the BEC set at 6.0v and there is no need for more power either.

Power Hd servos
has anyone used these for some time yet? In particular the B2 B3 B4 as well as the Storm 2 Storm 3 Storm 4.
Im looking to order a couple servos and was pretty set on Savox or Protek. But at the price of 2 of these compared to one of those. It’s kind of a no brainer.
Just wondering on quality. I know so top drivers use them but they are sponsored and really don’t car they will use them and replace them at Will. Trying to search reviews and coming up empty.
As as far as I can tell the servos are the same aside from the Storm having a full aluminum case and the B Series looks like the top is plastic. Or if it is aluminum it’s not machine to look pretty.
Any info would be great!

Well, I guess I'll give updates on the Blue Bird BLS-29A here now. I raced with it on Saturday and it still sounds and works like new even after some pretty bad crashes. My ESC only has a 6V/3A BEC which seems to be dying with this more powerful and current hungry servo so I'll be getting an external BEC to use until my new ZTW Beast Pro ESC gets here. Occasionally steering would go out for a few seconds while the throttle kept working. The servo is still fast, smooth, and strong so it must be the ESC. I'll report back on how it works with a better BEC.

I put two power HD 23kg in my mbx7t I just got. Just received my receiver pack and receiver today so I'll finish it up tomorrow and test them out. I figured for 40 bucks a pop and a free aluminum servo horn with each, if they are bad its not a big hit. If they prove to be good I'll swap them into my buggy and get brushless versions for the truggy.
How bad can they be? I've had cheap fma servos work awesome and my expensive futaba 9450 crap out in a season and stop centering. (Been out of the game a while)

They will do fine, we ran them in an ET48.3 and EB48.4 with no issues.
Is that a OS .21 RG in there?

OS RZ buddy. This motor was in my original Mbx4 that I raced back in the day. Took the buggy out after sitting for the past 6 years and broke it after two tanks. Put it in an mbx4RR parts car I bought and broke that due to a faulty servo horn. Retrofitted mbx8 arms on it and bought the truggy. Motor ran so good I threw it in the truggy and bought a 50 dollar sportworks motor and put that in my RR. That motor is a beast as well. Looking forward to see the RZ throw the truggy around. Love that OS engine.

Power HD WP-23KG
Any experience with this servo? I picked one up to either use in my Clod Buster or one of my crawlers. Waterproof, really good specs, and was cheap. I already have it, just wondering what y'all's thoughts are.

Well the Blue Bird BLS-29A started going in and out. It has full power and speed, isn't making noise, but it just stops working for a few seconds after a while. Flight Comp is replacing it so hopefully it was just a lemon.
