Seminole vs RV-12iS
The Seminole leads, topping 6 of 7 compared metrics.
Put the Piper Aircraft Seminole (introduced 1978) beside the Van's Aircraft RV-12iS (introduced 2011) and the trade-offs sharpen fast. Both are trainers, which makes them natural cross-shopping rivals. The clearest separation between them is range, where the Seminole has the advantage.

Which mission suits which aircraft
Both aircraft are built for short-haul and regional hops, so outright range rarely separates them — the call leans on cabin (the Seminole seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.
Which should you choose?
On published specifications the Seminole leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The RV-12iS can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
