In at the deep end Dadio!
Go have some fun.
You can watch for ever and it will not be as instructive as taking the plunge just once!
I would just say that I had my own motor bike at 5 years old, and raced karts from the age of 12. I currently take part in on-line car racing sims. My brother also raced FF2000 and we both agree that RC car racing is the most difficult thing we have ever tried!
We are both awful at it too.
