The RC models of SmartFish are powered by a ducted fan, driven by an eletric motor. We use these models to validate the stability predictions from the CFD calculations and to test overall flight behaviour. The thrust to weight ratio is in the range of 1:3 to 1:4. Our intention is to test the SmartFish design with a thrust to weight ratio similar to the one of business jets. The Cessna Citation X for example has a thrust to weight ratio of 1:2.7.
Compared to conventional RC planes (wich have often more thrust than weight) the SmartFish RC models are underpowered. But despite that all our models have excellent flight characteristics and also performances!
