Hi,
I`m working on the UAV flight dynamic model. It is a piper model with wingspan 2 [m] and length 1,2 [m]. The dimenssions are not the problem, but the weight is aproximatelly 5 [kg]. And that is the problem. During modelling It appears that when I put the empty weight smaller than 91 [kg], AirWrench is showing a dialog window with a problem: "Empty weight too low". Is it possible to model a flight dynamics for such a small airplane?
I would be very gratefull for any response.
