There are many RV and Rocket builders in Indy. I just left Greenwood and moved to Martinsville II87. There are several in the hangars there at Greenwood. Jim Truitt has an RV-8 with a military scheme in the second row of new hangars and down about three more rows is Brad (forgot last name) who flies a Red, White, and Blue RV-8. There are also a couple of RV-4s on the field. That's just at Greenwood. There are 4-5 RVs at Mt. Comfort, 3 down at Franklin, 4-6 at Hendricks County, and about two dozen more scattered around central Indiana.
Head over to Putnam County airport most Saturday mornings or Columbus on Sunday around noon to meet up with the group.
