XRAY - Model racing cars

hello xray members. i bought before few months an xray kit (nt18t)
i assembeld it and it all worked.
it was laid in the closent for few months until today.
i pull it out from dust and i want to roll out outside of the street.
well i charge glowplug starter car battaries radio system and the starting box
and i figure i had a problem

i had this problem with my m11 , just rebind your receiver and transmitter and it should work fine.
