I have to admit that's one I don't have on me. I'll pick one up and see.

In these, you are right. My HB servo horns were really tight. (all three of them) I didn't hammer them but in my case, it was a few light taps and push them the rest of the way with the screw. To get them off is with a lot of patience and just wiggle the horn and pull with my fingers or pliers. I prefer to scratch the horn rather than the servo case. But at the end is worth it. Servos are really smooth, fast and strong. I am surprised that I nailed a pipe so hard that snapped the screws of an ackerman plate but didn't strip or damaged the servo(T250) on an E buggy. That was my durability test. LOL

Worth it?
 

Been running a t-180 low profile for the last few months in 2wd buggy. Very smooth and precise response, centers properly. Bought a t-190 for the wheeler.

They're a little pricey, but I haven't regretted the purchase.

Determining if they are "worth it" is definitely case by case. Here's a short version:
I wouldn't skimp on other critical parts (radio or esc for example) or bust your budget to get a Tekin servo. However, if you want the most accurate servo money can buy, I haven't found anything better in 15 years.

Here's the long version:
To me they are worth it. When it comes to electronics I have always purchased for the long haul, so price doesn't concern me as much. I know I'll use them for 4+ years and then put them in my kids cars after that. At one point, I had a pair of Futaba BLS451 servos that were nearing 8 years of service.

The Tekin servos are definitely better than any other servos under $150, even without taking advantage of the programming options. I've had just about every brand of servo since I started racing, ranging from $20 to $200. It might seem obvious they should perform better because they cost more, but the point I want to convey is that I haven't found a servo with similar performance for less. You can definitely find servos that have the same specs for speed and torque, but the precision, consistency, and accuracy is unavailable in less expensive servos from my experience.

Comparing Tekin to other high end setups like the Furaba S.Bus servos, they are both extremely capable. I do like the Tekin interface more for programming over the S Bus.

After running Tekin servos exclusively since this past spring in various 8th and 10th scale vehicles, I've honestly noticed fewer mistakes and more consistent laptimes, especially in 1/10 buggies where precision is everything. Fast laps haven't changed, but my average lap times are noticeably closer to my fast lap. I had a $60 Savox servo in my B6 and a $200 Futaba servo in my B64 that were both replaced with T-180 low profile Tekin servos. The B6 was a massive improvement in consistency. The B64 wasn't as noticeable, but I went from a $200 full size servo to a less expensive shorty servo and it was better overall. You'll have to fight me to put any other servo back in my 10th scale vehicles. :lol:

I run a T120 low profile servo in both my Xray T4 cars. I was using a Savox previously which I never thought I had a problem with until I tried the Tekin. At first it took a little getting used to the speed of the Tekin, I'm using it at 7.4V BEC so it's turning 60 degrees in 0.05 sec.

Once I got used to the speed and the ability to change direction so quickly, I started to notice the accuracy and on carpet with my T4 '18 I was able to be more consistent compared to the Savox. It feels like a higher resolution of steering if that makes sense. More repeatable and accurate, if I made a mistake or clipped a barrier I knew I was going to before it happened as I made a steering input error. Like wise it is easier to correct small mistakes before they happen and therefore improve my average lap times.

Being in the UK and struggling to find Tekin products in stock, I bought both mine from the US. Even with the additional tax and import charges I think these servos are worth every penny.

I haven't received mine back from Tekin yet, but am probably still going to order another just out of curiosity and the fact I need another backup servo. They seem of good quality and am hopeful they can perform as well as my ancient RP servos.

I haven't run it yet, but was able to fit a 25T Team Associated FT Servo horn to the T-120 with no trouble at all, just tightened the screw to pull the horn all the way on to the servo.

any fitment issues with yokomo Servo horns?

in comparison to the futaba S9372SV or S9273SV servos, which servos appear to match the performance the best?

How can you tell that these servos are made in China with "submar" materials?
Can't you just add shims and spacers to fit the servo properly? Servos aren't all built to the same dimensions.

If you can tell where something is built by just looking or touching it, you sir need a job doing so. That said, there are a ton of variations in servos; mounting holes, deck height, etc. There is no "one size fits all" dimension. What we can do is take this feedback and work on making changes to them for the future.
