First of all this is just based on my experience.
Before I join 1/10 scale , I was playing the Mini-Z ( MA-010 ) , it was fun, learning process , driving skill , indoor with air-cond , lot of races so it was so good. until the shop was close.
So I have no choise to choose, so i have to choose the track that nereast to my home. That is 1/10 scale outdoor asphalt track.
That is the begining I join the 1/10 EP...
Well the feelling is totaly different , but the 1 year of playing mini-z help my driving skill , in 1/10 I have to learn the technics / the way to drive 1/10 car.
It depends on your $$ . If you Extra $$ yes you can make your own mini-z track at home , If not just focus on your 1/10 at the end your have your skill improvement....
