You don't see many threads about the kraton 4s. I bought one myself. Going to go with the castle creations 2400kv 3674 system in it. Savox SC-1267SG servo. Want the metal diff upgrade, cvd upgrade, and some skid plates for the bottom.
I ordered a few sets of tires already.
The only thing I wish they would make is a center diff for it. That would totally transform this truck and make it much more manageable at higher speeds
