A digital magnetic position encoder uses Hall effect sensors inside it, but that doesn’t guarantee accuracy. Brushless motors use Hall effect sensors and are accurate to 60 degrees for 2 pole motors. Tekin lists the encoder as accurate to 0.2 degrees on their website.
Come on, you can come up with better selling points than a 365 day warranty. Every servo comes with that, and its only for manufacturer defects. All servo's from reputable company have that. I'm also pretty sure its industry standard to be element/splash proof for most higher end servos. I do like being able to program center, but how many servo's actually loose center?
Congratulations. You latched onto the one thing I listed that is mostly standard for servos over $50.
Honest question, how many servos when properly installed have had the ears break off or wear out?
I had a set of Futaba BLS 451 servos that I loved. Used them for almost 8 years without issues in many cars. Ears failed, ending their run. Also had an Airtonics servo lose the ears after 3 years and a Hitec case gave out after a year. When I buy servos, I’m in for the long haul. Rock crawler, truggy, and monster truck servos are known to lose them as well. 10th scale buggy, probably not.
You stated I simply asked for you to prove these things. Specifically the bolded parts, which you state make the Tekin superior in some way.
Re-read your post. You asked how a servo with the same specs as a Savox could cost so much more. I listed variables that affect price (in general) and then highlighted 3 that were for sure better on the Tekin servos.
FYI here is an example of a cheap servo that uses the same "superior" technology as Tekin's position sensors
Cheap Servo
Yep, it is superior technology to a potentiometer. That’s why that servo is $20 instead of $14 like this one: https://www.adafruit.com/product/1404
It added cost.
my original question still stands, everything you've told me is just marketing stuff. Can you even tell me the type of gears used in the T-440?
Your original question was why does it cost more than a similar Savox. I’ve taken the time and listed several things that you decided don’t matter to you. They matter to myself and others. As far as the type of gears, we’ve been told it has a high strength steel output shaft. That’s all that’s been released so far. Seeing how you can’t even back order them yet, we will just have to wait.
Edit: I want to add, the only reason I keep using Savox is because its the servo's I use and are known to me.
Story time:
I’ve owned 20+ different servo models from 6+ brands over 15 years. 6 Savox, 7 Futaba, 3 Hitec, 2 Airtronics, 2 Bluebird, 2 Ace, and several cheap brands among others. My favorite servos out of all of them were the BLS451 I mentioned above. Lasted forever, relatively speaking. The specs? At 4.8 volts: 0.13 seconds and 118 in-oz. Absolutely pathetic compared to what the others listed on the box. They were the absolute best on the track. I even ran them in 1/8 buggy with no issues on high voltage. I don’t put all my stock in the specs listed on the box. There is more that makes a servo feel accurate and connected on the track.
Currently I have a Savox servo in my 2wd and a Futaba S.Bus2 servo in my 4wd. The futaba is rated as slower for transit time, but I guarantee it has a lower latency and is more accurate because it feels better on the track and looks faster when playing with the servo on the workbench. I wish I could afford Futaba servos in all 4 of my cars, but I can’t. Additionally, I usually install my personal transponder on top of the servo. I had to move the one that was on the Savox because I was getting missed laps if I turned the steering wheel as I went over the timing loop. Stared right at the dB numbers coming from the encoder and they would drop if the servo was moving. No issue with the Futaba doing the exact same test. Both cars are identical otherwise.
Tekin servos appear to have all the top end electronics as the Futaba S.Bus servos, but for $70 less than the S9373SV. If that ends up not being the case, I’ll let the world know. To me, they are a bargain if what they claim for accuracy is true. I buy all my electronics for the long run. Heck, my RSX in the 2wd is closing in on 5 years old since I got it when they first came out.
