That makes alot of sense, And I was having issues with just rolling the throttle, I think the smallest i can go is 75/23, I'll see what happens and if i can make it work or just save this set up for a real touring car. But I guess we can rule out the motor and esc and I do thank you for all your help.

Question for Randy. (sorry if this has been asked before)
I'm hearing other ESC brands are testing with very low drive frequencies for stock class racing, like in the 1000Hz range.
Will the RSX be capable of these low frequencies?
Would this be an upcoming firmware update?
thanks,

Maybe, We go down to 2khz now and so far have not found a reason to go lower. We easily can as our hardware supports much lower frequencies if we need to go there. One of the best things about Tekin is that we are often way ahead of our competition when it comes to hardware. This allows us to offer free as needed software adjustments to bring your ESC up to the highest level with a few mouse clicks.

Back in the brushed days (so not sure if still applies) but really low freq usually increased heat.

The theory can be the same but we don't see it typically.

ok. thanks for clarifying. Back in the day with Keyence brushed ESC's we could run really low freq and cook a brushed motor. I have been running in the lower range with the tekin stuff and not had any issues just not sure if there was a "breaking point" in the brushless world.

Is there any harm on releasing a firmware that will run at these low frequencies so tekin racers can run them if they feel the need?

Potential harm...not likely. But I'd have to see lap time improvement to spend the $$ to make the change and get ROAR approval for it.

Running a brand right now that advertises a 32bit CPU and does the frequency down to 1000Khz.

They state that lower frequency will give it more agressive throttle feel and less overall RPM. Going the other way does the reverse and increase heat in the ESC.

One thing I was curious about was does it also increase (when you go to a lower frequency) heat in the motor?

Playing with the setting for that brand it does fee more punchy.

For the Tekin RSX versus that RS Pro Black edition, which one would be better for 17.5 stock 2wd buggy, and also for 1/10 4wd open?

I don't have a smart phone, so is there a cheap tablet you guys recommend to grab for adjustments?

RS Pro BE for 17.5 and RSX for mod 4wd. As Randy always says get the right tool for the job.

According to the play store the tekin hotwire app will work on any android OS 3.1 to 7.0. You can attach using USB cable or Bluetooth (BLE) compatible device if you have the Hotwire 3.0.

I run an RS Pro BE in my EB410 13.5 Stock indoor clay car and also have an RSX running in another EB410 indoor carpet car with a 13.5 in it
Honestly; if you stay stock class, the RS Pro BE is perfect... I got a screaming deal on my RSX off here and did it and when i land an ET410 when and if
that arrives... the RSX will goto that and I will put and RS Pro BE into the carpet buggy. RSX does weigh a touch more than the RS Pro BE FWIW.

thanks for the info!

Using an EB210 conversion, maybe the RSX all around would be best as a layout change of the electronics thinking of moving them forward on the chassis, plus, some talk about mod class in the future.

Also an ET410 (maybe changed to a ET210) is in the cards here too

Anyway thanks for all the info!

Anyone is using the RSX in touring cars ? how about the experience ?

Plenty of people do.

Many of the great advanced braking features of the RSX and smooth throttle will make it a great TC ESC. Tekin top of the heap in the onroad world.
