Question on default gear ratio

[nrgskill]

Hi, I already have an Hobbywing EZrun Max8 with 4274 2200kv motor with two 3s batteries.

Does the default pinion/spur gear ratio fits my electronics or shall I buy extra parts in addition to the basic kit?

A lot of people use that combo on 4S. If you like more power, you can make 6S work with the 2200kv motor. You would want to use a tire like the original Badlands (5.85"), a 15T pinion, and 2 motor fans.
