Ink is good and worth the time.
The only thought I have about simply flying with a group is that of bad habits. If you really want to learn the basics find someone like Ink or one of the trainers. Otherwise you are just going to get frustrated without learning how it works. Groups should require another level of training in the 'finger four,' Loose Deuce or US Navy Division tactics, all very similar. Most groups fly in a horde, which means you learn the game, not ACM. To win you will do most of what the real aces did way back when.
Take Ink up on his offer. Look for other experten like him. After that ask about solid squad tactics. I don't know about the 113th but Traveler has a good rep. ACM first, squad second.
My two cents, for what its worth.
