XRAY - Model racing cars

hi everyone,
this is my first topic in your great forum, my name is Ali and I'm from Kuwait, first, i want to thank the XRAY team for making this great car, i've been in the RC car hobby for the last 16-17 years maybe and haven't seen a car better than this one.
i received mine about a month ago and installed it the very next day.
i've just bought the other parts and i NEED your profesional opinion guys:
