If you're looking to start doing acro in your RV, you don't necessarily need RV-specific training. If you get safe and comfortable doing basic maneuvers in a Super D or Pitts, then you should be able to explore this on your own in the RV with the knowledge that the RV is a cleaner airframe. But sure wouldn't hurt to have an experienced RV pilot train you a little in the type you're flying.
