12v battery and 4wd tyres

[MartP]

Hi

Thanks to everyone for making my son Josh and I welcome as we looked around over the past couple of weekends.

We are building up to racing our out-of-the-box car in the next couple of weeks and going from there with our racing.

Two quick questions:

1. What capacity of 12v battery should we get to power the charger? I.e. what will we need to charge our lipo battery the 5 times or so it will need? Any recommendations as to where to buy it?

2. What 4wd tyres and inserts should we get? Our buggy is a 4wd and came with tyres out of the box but we thought we'd get some decent tyres on it from the outset. A gentleman did recommend some tyres to us but we forgot what they were by the time we got home! Schumacher mini spike silvers?

Thanks,

Martin.
