I fly a PA18-150 Supercub and am building a 9. Comparing specifications and performance between the two is very interesting. To make the numbers more accurate, I'd like to know if anyone has performance results using 150 hp engine on the RV9? Here's what I have from the PA18 POH and Van's numbers for the RV9-160.
