About this part

The Hobbywing OTA Smartphone ESC Module Programmer is designed to wirelessly connect your ESC to your smartphone, using the Hobbywing HW Link APP to clearly display and adjust all parameters of the ESC. The graphical man-machine interface of drop-down list boxes and scroll bars is set up to make the parameter adjustments easier to use and more specific than ever before. The OTA programmer supports real-time data recording and stores the data in its memory, allowing the driver to access the current running status of their vehicle. With additional features such as seamless bluetooth transmission and a one-touch factory reset button, this programmer takes so much of the hassle out of managing your vehicle's ESC.

NOTE: This module is compatible with some XERUN, EZRUN, PLATINUM and SEAKING series ESC's. Refer to the ESC manual to ensure that the OTA programmer is compatible.

HNL pro mod MTVerified owneron Hobbywing OTA Smartphone ESC Module Programmer

very easy to use and best thing it has a reset button on the back if you ever run into problems. i love the app it's very user friendly and tons of adjustments. do your research on the settings and watch charlie on you tube. play with it and see what those settings do. alot of times the factory default works very well.

The module I received was likely previously owned. Despite multiple resets by using the small button on the back of the device, all connection attempts failed. I attempted to connect by WiFi and Bluetooth. Both modes of connection ultimately failed. The previous owner gave this device a unique name that appeared in the Bluetooth mode. I will be returning this as it is not functional.

MY EXPERIENCE is as follows. My android device will not see it as anything except bluetooth, fought with it for two days. In the videos I've watched, as the HW tech support only repeats the manual, the module is always recognized as wifi then the app opens up to a world of beautiful operations. My guess is the android device has to be a newer version, something that should be advertised so money isn't wasted on a product that doesn't work. Taking someones money in exchange for a misrepresented product is just theft. AN UPDATE, Android 7 must be to old as I just had to replace it with version 12 and the OTA works perfectly. Amain offered troubleshooting help and Hobbywing was exceptional in helping solve the issue. Thank you!

Worked right out of the box and does what it is described as doing. So far I am pretty happy with this purchase as far as tuning and ease of use.

Wasn't sure how I was going to feel - I have plug in ESC programmers, but this takes it to another level. I can now change and modify settings on my Hobbywing ESC that were clumbsy with other brands and programmers. I downloaded the latest app for my Android S23 phone - I think there were a couple firmware updates. I did like the fact that I could leave it plugged in during practice - stop on the side, reprogram and reboot the ESC. Back at it!! It was nice to adjust punch and drag brake and dial down the throttle for a newb.. I own one and now many Hobbywing ESC's to go with it!

What reviewers say

Most of the 20 reviewers rate the Hobbywing OTA Smartphone ESC Module Programmer highly, praising its ease of use, the phone app's range of tuning options, and convenience for adjusting settings at the track without removing the body. Several note it works well with multiple Hobbywing ESCs and that the reset button helps with problems. Recurring complaints include the price (one reviewer called it $50 and objected to being unable to keep it plugged in), a port that does not fit some newer ESCs without a reducer, and one reviewer's device arriving as previously owned and failing to connect. One reviewer had trouble connecting on Android 7 but succeeded after upgrading the phone to Android 12. Connection problems were resolved in some cases by reinstalling the app. The verified-owner status of several reviews is not uniform, and a few reviews…

  • + Easy to use
  • + Useful app with many tuning options
  • + Lets you adjust settings trackside
  • + Reset button on the back
  • − Connection issues on older Android versions
  • − Requires a reducer on some ESC ports
  • − Cost criticised
  • − Cannot stay plugged in during use
