Recommendations for that new guy.

If you have a MFC01 unit, you're are not going to need the ESC-302BK because the MFC01 unit has a ESC built in. The MFC unit is a all in one component.
I personally like to use FLYSKY FS-CT6B it is a 6 channel 2.4GHZ with analog trim, digital proportional radio perfect for working with the MFC unit. You will enjoy having the 2 extra channels there is always room for upgrades on your truck, its better to have than have not. You can purchase it on EBay for $20.00 to $50.00.
As for the battery don't use Lipo or LiFe battery's with the MFC unit. Just use a good premium 6cell battery. Use a smart charger only, most chargers can detect parameters in your battery, But you want to use a charger that will stop charging the moment it detects something is wrong with the battery or connections. This will indeed stop any fires, over charging, battery or charger damage, and will save money in the long run.
