Tekin Servos
#31
This is the main reason why I can't switch, I run Futaba S9373SV with my 7PX which allows me to use the SR mode, switching to Tekin Servos would eliminate that capability.

We do not sell direct, other than softgood, discontinued items and scratch and dent on our cart. We prefer you buy from one of our dealers where you can make a friend and get some support if needed.
Servo are warrantied for manufacturer defects for 1 yr.
It is narrower band so they can send a signal more often, every 1ms, but the SHR mode is not exactly slow at 2.6ms. Normal bands in most radios are sending signals every 3 to 10ms which is plenty fast for RC car steering.
Inside secret... many top level onroad drivers actually turn the signal rate down to make the steering wiggle less due to constant correction down the straight and scrub speed.
That narrow band also means less resolution, less steps. This brings up another advantage of the technology in the Tekin servos. You can program the endpoints so you do not have to turn down the EPA in the radio to the 40 to 60 range. Most servos are set to travel 60deg each way with full radio signal range and most cars only need about 30deg of servo travel so you reduce the EPA to about half. If you set the endpoints in your car with our Hotwire program you can leave your EPA settings at 100 and have the full signal range for better resolution.
You can actually set our servos to travel more than 60deg. They have no physical stops because of no potentiometer and can travel a full 360 degrees. In fact they can travel up to 5 rotations both directions and be used for other applications than just steering.
These servos are truly different and innovative. Considering all the options available in the market it would not have made sense otherwise to offer them under the Tekin brand.
Not sure you have to be a pro to notice, but if you are just bouncing off the pipes you may not see the difference. Then again maybe some of those mistakes are not really you and more due to inconsistent servo response...
A few of our team drivers initial comments below.
"The first time i ran this servo (T-120) was amazing, i have never felt more in-tuned with the servo."
" Not sure how to explain it other than it just feels more connected. I do not have to counter steer in difficult sections and it does not seem to overshoot. I also do not have to trim the center each run unless I bang the pipe and actually move the linkage."

On a side note: I said the same thing as your team drivers when I switched to a better radio.

Street price will vary pending order discounts offered and free shipping on some sites or buying from a dealer. We sell for the same price to everyone and let the market decide.

Not sure we really see the advantage in RC cars of SSR mode or any of the narrow band special modes many of the brands offer other than it only works with their products. Maybe in 4d helicopters with ninja pilots.

industry-leading Accuracy
Tekin Prez kinda alludes to this several post back, but so far both times asking what the resolution is goes ignored. If Tekin's accuracy is "industry-leading" then telling us the resolution over 360 degree sweep should be no problem.

Resolution is not the same as accuracy. As an analog position sensor, a potentiometer itself has infinite resolution. The resolution that companies list comes from the processor (10-bit for 1,024 and 12-bit for 4,096), but that doesn't change the fact that a potentiometer will provide different readings for the same position if the temperature changes. Digital position sensors like magnetic encoders don't change with temperature, thus they are more accurate no matter how much the conditions change.
Tekin has listed +/- less than 0.2 degrees as the accuracy of the servos. I would be more interested in Tekin releasing the accuracy of the other servos they measured for comparison.

I noticed Tekin routinely state these servos will have This is stated several times on your Facebook announcement, can any one at Tekin give us something so we can compare to other manufacturers?

I'm following this thread because I'm extremely interested in the product, and will order one the day I see one finally in stock. If you're not interested, just move on man.

My money would be on 1,024 as the resolution. It's a common resolution for sensors of that size and the fact Tekin claims an accuracy of less than +/- 0.2 degrees, that checks out. If it was exactly +/- 0.2 degrees, then 360 divided by .4 is 900. If we add in the 'less than' part and divide 360 by .35 we arrive right at 1,028. Basically right smack dab on a 10 bit resolution of 1,024.
