Ratings and reviews

The app works as inscribed, but it's a real battery drainer, AND you have to keep the car rather close to the device for solid connection. It's fun completing all the challenges and earning all the rewards, and it also IS possible to build your own car, as long as you have all the motors hooked up, and all the motors are calibrated and spinning in the exact directions as in the actual models. The excavator is a bit easy to make your own model out of, while the Xtreme offriader meets standards.

I had absolutely no issues setting this up on my Galaxy Note 20 Ultra. The app seems to work well, and the BLE seems to be responsive. My only real complaint has to do with the controls for the Off Road Buggy. When you use the 2-stick control, the throttle is on the right stick, and the steering is on the left stick. This is backwards to every other R/C car controller I have ever used. It would be nice to be able to swap the steering and throttle controls in the app.

The app needs work for Android 13 and the Cat D11. The "Test" mode movements do not match the screen. The calibration requires you to go back through and re-test immediately before or it will just freeze up. Once (if) you finally get it working it is good. It is borderline incompatible with android at this time though. Please test on the latest Android version and fix!!!
