Hi dan first of all it's nice to hear from new racers

Firstly what tamiya paint are you using as I spray many shells using tamiya and it's as good as any, there are two types PS (polycarbonate) and TS (acrylic) YOU NEED TO MAKE SURE IT'S THE PS PAINT. The polycarbonate paint flexes with the bodyshell as it's bends if you use acrylic it will just fall off when you bend the shell.
Secondly if you are already using the tamiya PS paint then you mustn't be washing the bodyshell either at all or very well, you need to get rid of any grease or contaminents before painting.

Tyres- basically on our track and most other tracks we use Schumacher yellow mini spikes when it's dry and ballistic buggy green mini spike when wet
And on Tarmac for bashing just use the same but use your old worn ones

Speedo and motor
The Orion R10 is a superb speedo I currently use it along with the HPI flux motors which are super quick and a very good price too

Personally I'd avoid savox as they don't last long and the gears easily break.
I would recommend sanwa servos and xpert rc servos

Most lipos are pretty similar but which ever brand you choose more important is the C rating the higher the C rating the better power output and punch you will have

My advice on budget would be simple, "If you buy cheap you buy twice"
In this sport you generally get what you pay for....
