Need engine sound turnoff ability while idle – Batmobile™ R/C Controller Review

I absolutely love the car and i am still exploring the App’s ability tonstill be connected to car while I operate outside home. But as soon you turn on switch on car, it constantly makes engine sound even though you may keep it idle for any amount of time. This is really annoying and taking the fun out of having this car. Please provide thst abikity to turn off engine sound when car is idle!!!
