bought a grom a few weeks back and have been enjoying bashing it. However from the get go noticed that reverse would sometimes take a couple of trigger taps to engage. Now after the last run on battery and having recharged battery there is no drive whatsoever forward or reverse. Steering still works fine. Have tried re-binding the remote as per instructions and no luck as well as new batteries for remote. When starting it up the esc sometimes doesn’t even beep. I’m out of town at the moment so will take it back to the store when home to see what they think. However while I wait thought I would ask here to see if this is an easy issue to diagnose (ESC fried or something?)
