Brushless Servos (who's taken the plunge?)
So with servos ranging from 4.8/6v-7.4 to unregulated 2s lipo, waterproof, metal to titanium to steel gears and more, a lot of us are seeing brushless servos on the rise and their prices finally on the fall to where they are a comparable option as most of us have a hard time justifying $150+ on a servo but have no problem spending $100 for a good, piece of mind coreless. Now that brushless servos cost in between and lower on the street, I'd like to hear from those who use them now and those who have been for years as their benefits far outweigh the price to those veteran users and if there are even any negatives to go along with the pros? My first question is if they are really that efficient that I can swap out my coreless Savox SV-1271 which needs an external bec (for those of us without an RX8 gen2) for a 2273 brushless servo and do away with the external bec and maybe just get away with a glitch cap? ….if that's the case, I'm sold! ….but is this reality?

I've ran the Futaba BLS ones for years. In short, they do seem to be everything they are advertised to be. They seem to be smoother, I have never had a brownout issue, and mine have been 100% reliable. I can't say if it will allow you to eliminate the BEC in your specific case (Savox is still Savox and in the past, when most people upgraded to brushless, they "upgraded" brands as well) but in general, I would not hesitate to say brushless servos will be worth the money.

Futaba BLS551 here in an elec touring car.
Err, umm, it's awesome. Changed from Savox 1251. Quieter, faster, smoother.

You forgot however, to add the Futaba's twice as expensive.
I'll stick with the Savox. All my electric and 1/10 nitros have the 1251's. Always thought best bang for the buck. And knock on wood, no issues as yet with any.

Coreless digitals are more precise than brushless.

I have the Savox 2274 brushless high voltage model, and it is so smooth and powerful. It snapped my wimpy aluminum servo arm. It cost $115, and you can get 10% off from Amain. Specs are .08 sec and 347 oz. in. torque @7.4 volts, highly recommended. No glitch buster needed with these. Amain $103.49 right now.

I've had a few Futaba BLS451 servos in 2wd offroad rides for years. Have been very pleased with them. Quiet, smooth, seem plenty quick and powerful in the car, easy to power. They haven't developed any slop that I can tell.
My son tried one of the servos with better ratings. Noisy and overshoots with quick inputs. Fortunately his speedo could at least power it. It didn't seem any quicker or more powerful on track. Didn't take long to develop considerable slop. He pulled it and went back to the BLS. Others in our area also have experienced great results.

I've recently switched from a Savox 1251 to an Xpert low profile brushless servo. I felt like the steering was much more precise and a heck of a lot faster/more powerful. The Xpert isn't quite as smooth as a BLS551 when turned by hand, but feels more precise in the car.

Speed's about the same as the Savox but I'll give you 'quieter' and 'smoother'.

I am using an RX8 Gen2 with it, built in 7.4 volts.
