I need to get the dimensions of this ESC right...

31.2 mm (Width?) x 37.2 mm (Height with fan?) x 21mm (Length? With solder posts?)

Beep at idle?

Yes, mine too. Not a beep, but a quiet "buzz" or "chirp." It seems to correspond with the internal temp indicator (as in it will make the sound when the lights flash to display temperature.)

I figured it was normal, and just something new to the RSX but only mention it since someone else brought it up.

The "Chirp" is an audible indication that the unit is in Blinky mode. Sometimes units are wired and installed in a vehicle in such a way that it makes it very difficult for the Tech's to see the LED's.

Yes Jeremy is right, if the unit is in spec mode we have an audible "chirp" indicating spec mode which is kind of nice for the tech guys.

Been running some prototypes in my cars for a while now and it's been amazing. My LHS Superior Hobbies just got quite a few in if you're looking for one.

Got my rsx today and having trouble using the droid app..hotwire installed on my tablet I'm able to play with it in demo mode...once I plug in the usb it opens tablet recognises hot wire, once I plug hotwire to the included data adapter nothing happens no lights on rsx but light on at hotwire...

Data cable plugged into rsx, hotwire light on hotwire app loaded to tablet...please advice..

what version android
does your tablet support OTG,if so does the cable work on a usb flash drive

Version 4.1.1 on a galaxy tab 2 using the samsung usb adapter

plug esc into HW then plug into cable then plug it in to the tab,does it ask you do you want it to remember that cable

This is how I run the app in all cases:

Plug in the adapter and hotwire into the esc FIRST.

Plug the hotwire into the Android Device.

Launch the app.


Now if you've done this a few times you may need to stop the app and force close it, and restart.

On the tab 2 simply go to the task manager and close the app.

I got it....had the data cable plugged in backwards...works sweet now!

First time on the track tonight with the RSX. It worked flawlessly and had noticeably more punch and smoother breaking than others. Running a small track withe the new 22-4 a 6.5 Tekin gen II, 17 T pinion and all kinds of power and punch. Esc running at 104 deg and motor at 117 deg. Another great Tekin product !

I've been using Orion R10 Pros for the last year or so, mostly, but I'm going to back to Tekin. The service is too good. Plus they are compact and easy to mount. I have a couple Gen2 RSs and I find that with the same 17.5 motors [in blinky mode] the R10 Pro has a little more bottom end. Anybody know if the RSX might have a little more hit than the RS down low? I'd really like to go back to all Tekin. I don't like dealing with Horizon for service. Anybody have any track time with the RSX? How is it?

I had that issue with my gen2 also where it felt weak of bottom and thought maybe rsx would be the trick also but there saying not to run a rsx on 17.5 pretty much, YZRACER said to try this
"Raise your Throttle Minimum up a few. That will give it a bit more snap on initial throttle input. Also make sure your Neutral width is around 10 to help take any delay in the trigger."
