Leviathan008 Posted June 16, 2019 Posted June 16, 2019 hello, I just bought the app-controlled batmobile, but when I use it in the second mode of use, speed control, from the app on my phone, a high-pitched sound is heard, in theory it should work normally, but it only works in normal mode without speed control, the same thing happened to me with the remote control of trains, same sound, maybe tlg has a problem with motors controlled by speed or I'm not lucky,by the way i tested without gears or conected to anything else, and the same thing that train remote control Quote
