ECX Boost - more advice

[TheNewGuy]

Hi, as my name suggests (and I assume I will regret making a few years down the line) I am new around here on Oople and RC racing in general.

So I am actually only 15 but have been going to a few race meetings down in Southport (SRCC) and when a bargain popped up on here for an ECX Boost with all electricals installed, I bought it!

So I went to the local model shop and bought a 45c lipo battery with my friend and completed my first race at the Woodvale event on the 23rd June. After my first race I decided that I wanted a slight upgrade to my (currently brushed) motor and a new controller as I was getting a lot of interference with other RC vehicles.

So, just wondering if anyone could give a newbie some advice on what to do from here, such as raising some more money to upgrade my items or what items to get next, or maybe some maintenance tips, so please, give me your advice,

Thanks!
Kyle.
