I have my ESC mounted in the rear like the 2.0 does. Only issue is that there really isn't a completely flat surface cause the battery pad that was there was removed by the former owner that did the battery mod. I have a Tekin RX8 and noticed it had come loose the other day while practicing. A buddy of mine suggested I try Velcro. Apparently he runs it in all his RC vehicles. I went ahead and peeled the old servo tape off the chassis and applied the Velcro he gave me and it seems to be doing fine. The ESC has a little bit of movement, but its not flopping around or anything. Its mounted pretty firm.
Anyone else use Velcro? Or anyone try it and have issues while using it?
