Trying to import a flybarless heli model to get away from "pitch up" tendency that is common on flybar Helis.... when I click download for model, I get a message "This file does not have a program associated with it for performing this action. Create an association in the Set Association control panel." I can't find a control panel anywhere to attempt this. Years ago I used Knife Edge to transfer models, but it looks like KE is gone.....
