The US Air Force Academy did a detailed study on the Cessna 150/150 back in 1996. It is very thorough and can answer a lot of performance questions. Somewhere... I have the original brochure from Aircraft Conversion Technologies that has "performance numbers" but it isn't as detailed as this report.
