RSX will do great in Stock. Down fall is weight as the RSX with fan is almost 30g heavier. now you don't need to run the fan on the RSX in stock so you can drop some weight there but the RSX is fully tunable for a stock setup and will run "blinky" so other then weight it will do everything the RS Gen 2 will.

I will agree with Kiro though with the very recent introduction of the RS pro this might be the best solution. Should not have any issues with heat and the RS pro with a mod 2wd buggy under most conditions assuming your not going supper aggressive with motor and is the new go to speedo for spec classes.

ON our motors it's very accurate. If the other mfg is using a similar thermistor it should be accurate.

The RSX is a great ESC but with the recent release of the RS Pro BE unit I'd suggest getting it for stock racing. With the new ULR design it's power you can feel dropping it in.

150/160 degrees Fahrenheit is what I meant. My RSX will stay in for mod and stock too. Think of an RSX with the same tech as the RS Pro...only a matter of time? @Randy are there thermistors on the board? Is that what they use? I assumed that there were just the hall effect sensors.

Ah, gotcha.

The tech in the RSpro is mostly a ton of FETs (48 I believe) to lower the on resistance for spec racing, but the lightweight design on the RS Pro isn't as great at transmitting heat buildup.

The RSX has fewer FETs, but a ton of direct contact between the all aluminum case and the power board, creating much better heat dissipation for mod classes.

Here is the pinout list for the sensor cable on all ROAR approved sensored motors, including a thermistor:

8.4.6 General technical specifications for brushless motors
8.4.6.1 If the motor is sensored:
It must use a six position JST ZH connector model number ZHR-6 or equivalent connector with 6 JST part
number SZH-002T-PO.5 26-28 awg contacts or equivalent. Wire sequence must be as follows:
Pin #1- ground potential
Pin #2- phase C
Pin #3- phase B
Pin #4- phase A
Pin #5- temp control, 10 k Thermistor referenced to ground potential
Pin #6- + 5.0 volts =/- 10%

Aha!, that's perfect - i didn't think to look for the pinout for it! Should be good to go then.

There has to be a temp sensor. Halls are only 3 wire and don't grab any temp info.

But i should be able to check with a multimeter on Pin 5 to ground though? I should have waited for the Tekin 17.5 Spec R...

Don't bother. Power up your car, hold the "INC" button until your ESC chimes. Then let the car sit for 20 seconds while it records data. Plug into it with a Hotwire and download/view the log.

If the temp is -60 or some unreasonable number that motor doesn't have a temp sensor.

The new RS Pro looks promising, however the price tag of 224 will push myself and others away from it. There are too many other options for a stock esc such as Hobbywing that has a 13.5 limit for half the cost.

I have a feeling once you see one in action you might have a slight different opinion on calling others equivalent but yes there will are less expensive options but will not say the perform the same.

If it performs it maybe worth the extra money. Will be anxious to see it in action.

But in Blinky mode, Blinky is Blinky! When you don't lift for corners, what else is left to feel?

Blinky just means no added timing. The RS pro has a lot less internal resistance than less expensive speed controls. Not that it will take you from the C-main into the A, but if you need every bit of power, you will notice it.
