I took mine for a quick bash over the local bmx track yesterday and I lost a wheel, luckily I found the nut. Im really impressed with this truck its tough as old boots, not broken a thing yet and its had a fair few crashes when my daughter has took control (honest!) Only problem Im having is getting the steering straight and keeping the ESC fixed, gonna try silicone sealant for the ESC next as d/s tape doesn't cut it.
