Hi, i am building the Rascal stunt plane, there are propeller 7x5 recommented at the Rascal plan ,and i am planning to use the ASP 12. I has maked the carburator for C/L use, there are 5 mm venturi, works well. I shall take bench running the ASP 12 with miscellaneous propeller from 7x3 to 7x6 to find calculated speed and thrust with the program ThrustHP.

Are the speed or thrust neccesary to make stunts?
