In August of 2017 I started a thread with questions about the RV-12/RV-12iS range numbers. One of the questions I asked was how with the RV-12iS at 5500 RPM and 7500 ft, the range could be 630 miles, while at 5000 RPM and 7500 ft, it was only 605 miles. It just didn't seem likely to me that at a higher speed the range would be farther. Those numbers still exist in the current RV-12/RV-12iS brochure on Van's website should anyone wish to verify that.
However, I see that they have now posted in the performance section on the webpage some new numbers that make much more sense to my engineering mind. They are as follows: At 5500 RPM and 7500 ft the range is listed as 528 miles, and at 5500 RPM and 7500 ft the range is listed as 631 miles.
These new numbers are in line with what I would expect, and I am pleased to see the update. As I stated before, I am very impressed the the current design of the RV-12iS and with the quality of Van's aircraft kits.
