Model airplanes provide an incredible outlet for one's creativity. A very dedicated individual could perhaps design, build and test fly one full-size airplane per decade and it would cost thousands of dollars. On the other hand, a model airplane can be designed, built and flown in one day for $100 or less.A 2001 study by Paul Ross examined 40 reviews of electric model airplanes in national magazines. He concluded that their average propeller efficiency was 39%, half of what it should have been. There is clearly a great need for an easy to use model airplane calculator.RCAdvisor's free online calculator analyzes the performance of your flying model airplanes. Great care is taken in the computations to ensure a very high degree of accuracy, although ease of use was the primary design goal. Our mission is to help you have better flying models through education and analysis. Our goal is to become the standard, most trusted reference tool worldwide for the design and performance optimization of flying model aircraft.RCAdvisor.com was founded in 2007 by Carlos Reyes.
