I knew the interface cable was available did not know it was not a dongle/copy protection device.

The software I am using is not a sim but design/analytical software and is not designed to interact with anything other keyboard or mouse. Its older but had a large data base in fluid dynamics including flight. They refer to it as aeromodleing but my understanding is in relation to full size. Newer versions no longer have this portion of the data base. The owner is no longer using this version so I am playing around to see is it’s of any value for our purposes.

What we have noticed so far is the model aircraft values inserted in the program coincide with those we observed with the actual model. We were worried about scaling down but it seems the airfoils we use in models as long as the information is correct result in near true predictions. The software engine is slow and single purpose. For instance you can change the variables of weight, angle of attack, speed etc even in a constantly banked turn and observe the generation of the expected airflow and separation of same prior to stall. In one instance the software predicted a continuous right wing panel stall each and every time in a straight ahead stall. This the model did with a repeatability that was uncanny. You cannot fly this software, each set of parameters are run by the software allowing you to only alter the variables during the execution.


If one could get an idea how a certain airframe might react it would certainly reduce the test phase. However it will not give an indication of the reaction of the same airframes while under RC control. So if the sim using the transmitter runs close to the actual model being flown by the same transmitter. Then if the data from the design can be put into the flight sim this might be a usable tool.

We have the info from several real world tests and would like to see it the information can be transposed to the sim then compare how the edited model fly’s in relation to the real one. It may not work or offer any data of value but if by chance it does it offers interesting possibilities.
