Hitec RCD31422S HS-422 Deluxe Servo

Among hitec's lower-end standard servos, this one seems to be an excellent balance of speed, strength, reliability, and price, though it doesn't win any one of those categories.I order these when I need them quickly and don't mind spending the extra bit over ordering from any number of Asian manufacturers. However, if you are willing to wait a little bit, some of non-brand-name Asian servos are getting pretty good for much less money. The thing that the no-brand servos just haven't caught up on yet is reliability. Subjectively, my Hitec servos last much longer, and I have yet to get a bad one (out of quite a few).

I use these in large scale RC planes. I just bought 4 to put into my new SIG Kadet Senior 2 meter, 78" wingspan, 8 pounds lbs. The servos are precise, quiet, and if you use a small #1 or #0 Phillips head screwdriver you will NOT strip the screws. These are perfect for scale/slow flying large scale electric planes. I do not recommend these for gas glow planes, or RC cars. The karbonite gears while being more precises, lighter, and not wearing down, they are more brittle and the vibrations from gas glow motors, and crashes from RC cars will more easily break your servo gears. If you fly large scale electric airplanes you will not have an issue with the karbonite gears and will benefit from the precision, longer wearing gears, and lower power consumption from analog servos.Advantages of this servo. Price $20 is very cheap for the quality you receive, especially in 2021 when prices of electronics are rising in this hobby.Analog is better for my SIG airplane, because I do not need crazy fast speed, or insane torque. Analog runs quieter and consumes 2.5x LESS power than standard digital servos. * Compared to Hitec D645MW, Futaba D3305Karbonite. Yes, it has its downsides. It is more brittle than metal or nylon, but it wears the BEST out of the three gear train materials. Karbonite can also be cast and made more precisely than metal or nylon. Karbonite has been tested to more than 300,000 cycles with little to no wear! Metal, you can get 150-200 flights until the gear-train flop poses a risk (surface flutter) and requires replacements. Why is Karbonite the best material for my Sig Kadet Senior? Because it's lighter, and wears the best, and provides excellent precision, and happens to be cheap too! If you are needing a servo that will get beat up a lot, or ran on a gas or glow engine vehicle, I recommend metal, but if your upmost priority is precision, karbonite is the way to go.Money not being an issue, I considered the ProModeler 90, Hitec D625MW, D645MW, Futaba S3004, S3305, BlueBird BMS-621DMG+HS, Onyx (Tactic) S45 MG. I decided on the Hitec HS-485HB Karbonite because the gears last longer for my application, are more precise, consumes less power, and is still very affordable.

Works exactly as it sgould

I used these servos in a 33% Miss Los Angeles. They work very well. Not much idle chatter, these servos respond quickly and smoothly. I'll definitely order more for my next project.

I needed some cheap but strong servos for a robot I am building. These are name brand standard servos so they are MUCH higher quality than China servos. They are a little on the slow side but they are plenty strong. The karbonite gears are also a nice plus, better than nylon since they are less likely to strip but less expensive than metal gear servos. I have about 10 years experience in RC airplanes and helicopters and would recommend them for trainer/scale airplanes. They arn't fast enough for 3D flying but would be ok for mild aerobatics such as aileron rolls, loops, ect. They would be pretty good for a fun fly model too. They include stuff servos usually come with such as screws, grommets, extra arms, and those little brass eyelets. The centering is also very good and I have yet to get any jitters. If you are on the wire between these and the no name China servos, do yourself a favor and pay a buck or two more for something quality.

The product was a great addition to my project. I was working on a automated solar panel tracker for fun and the motor was reliable and strong enough to move several small solar panels with ease. Would recommend if you care about quality.

I have been going through my fleet of RC airplanes in search of old standard servos and have been replacing them with this servo. I am replacing servos from Hitec that mention apollo 10 and Futaba ones that have the lines and dots for a logo.(That was a while ago, I know) I feel that these servos are the best value for the money. These servos only cost a couple dollars more than standard servos and you gain several advantages. You pick up more torque and the servos have karbonite gears which are typically more durable, all without sacrificing servo speed.

Its good quality, ive been using it always on some of my rc cars. Its tough, so far it hasnt failed me yet. I love it.
