Then any basic system as I showed would work with the included battery pack and charger.

If you want to upgrade, well, that's fine, but for a basic setup, the Airtronics or Futaba systems are just fine. I've used both, I prefer the Airtronics (personal choice) but both will work just fine.

As for the Airtronics, the basic servo, the 94102Z is a fine servo and I have a bunch of them and fly with them regularly. There is nothing wrong with the Futaba's but I just happen to prefer the Airtronics.
