Just ordered the T-250 as my Savox has seen better days. Will be using this as recommended by Tekin, for my XRAY XB8E 2018. The Savox has seen the years and was not centering correctly. It has been a real workhorse. Can't wait to see how the T-250 does? I guess I can add some oil to the spline just in case.

Got this and raced today. The servo was flawless and performed very well. I had zero issues with it and the servo arm was easy to use. A very dusty track and sliding every where, so the servo had a horrible workout. Got home and the screw connecting the servo arm to the link was loose. So I had to sand down the arm's edge so the surface is flat. Now everything is tight. i don't know why the flange is there, but it causes problems when used upside down.

Hi Guys,

I've installed my new Tekin Servo overnight and am super excited to give it a run. Setting centre and end points was too easy on the hotwire and I love this feature.

What I would like to discuss is the settings in regards to getting the most out of the servo. I'm interested to hear feedback on the "Feel" setting.

On listening to the RIP podcast last year I recall Randy discussing that in say a Off-Road 4wd Buggy if the track is rutted and grip comes up. The steering can be deflected and if the servo tries to return to position too aggressively this can cause spit outs.

I'll do some testing over the next few months and experiment with this setting. I'm interested in what those that have run this servo for awhile have concluded in regards to the feel setting.I'm interested in 2wd & 4wd buggies and Touring Car.

The Servos only connect to the PC version of the hotwire. It should work fine regardless of what car it is in. In all cases you have to unplug it from the receiver so you can connect it to the Hotwire. Has to be the PC version because it has to supply the power to the servo to turn it on.

There are no cases where you can leave it plugged in and just connect to the esc if that is what you were thinking.

Glad you are liking the performance. They really are different from other servos and people are starting to notice...

Got my 1st t180 in today can't wait to try it out this weekend.

Yes the digital position encoder is simply more accurate, consistent and less effected by temperature during the run. Also allows us to have superior software control that eliminates the typical overshoot many servos have. IE when you turn 20deg the servo may overshoot a few degrees and then turn around to go back to the 20deg position. The comment we often hear is they feel more connected and you do not have to counter steer as much. It is so direct it can actually take some getting use to. We also hear that you do not have to keep trimming the center point back to straight, unless you bang the pipes and tweak something physically

The programability in the Hotwire lets you set the center point and the end points ( throw). Instead of having to turn your radio e EPA down to the 50 to 70 range you can program the amount of motion to match your setup and leave the EPA's out at 100 to 150 max for better resolution. Always best to still set the center close to the natural center, but nice to be able to move the center point if you happen to put the arm on a few teeth from where it should have been.

There are additional settings for feel, and alarms for temp, binding, voltage levels, and loss of radio signal to help diagnose problems.

The gear set is also worth noting. The gears are smooth enough that you can literally push the arm and it will coast... Very Cool !

They are also very power efficient which saves battery and reduces heat buildup. Many servos literally pull 7amps or more when changing directions which is simply means it has very little smarts. Under load current is torque, but in most cases the servos are rarely under load for any length of time and mostly change direction a lot making those silly high current spikes add up.

This part sounds very interesting. Never thought to really play with the features of the servos like this. on the vehicles i have there is always just a hair or so offcenter regardless of how you attach the horn you end up trimming out. May have to give this a look.

that would be a cool feature somewhere on the servo.

Agreed. However it's not technically feasible to put it on the top of the servo because that would cause it to occupy the same space as the gears.

I have three of the 120 low profile servos.

under no load and not plugged in or powered up, all three act much different than each other, so I was wondering if this is normal.

One of them has some resistance when manually turning the wheels with my hands, its as smooth as butter, but there is some resistance.

The second one, still smooth as butter, but there is noticeably less resistance, but there is slight resistance.

The third one, again, smooth as can be, but there is basically no resistance. the weight of the stadium truck wheels pretty much move the servo arm.

So I guess my question to Tekin would be, is this normal? should there be that much variation among three of the same servo?
Is the loose one on its way out? or the tight one?
Would there be settings I could change if I had the servo programming cable? I already have a hotwire.

Thanks!
