If you plan on staying in this hobby for a long time dont waste your time or money on cheap hex. Ive had proline,losi,integy,craftsman they best one out of those were the proline but they wore to fast. and now i own hudy, best investment ever made
Its pricey buy grab the hudy set. this set has all the ones you need plus some. It included a 2.5 which works great if you strip a 3/35 screw,
