You will need:
2. Battery packs
3. Transmitter batteries (AA)
I would do right away:
1. Put better connectors on like powerpoles
2. Check all screws to make sure they are put in correctly.
3. If possible, use side x side packs and get a discharger / equalizer board
Thats about it. I usually do a full teardown on any RTR, but if you want to get going fast, do the screw check.
