I would like to announce my latest free App - the PRE-Flight Virtual RC Controller (for PRE-Flight Drone Simulator).
Convert your Android Smartphone or tablet to a full-featured, 12-channel, wireless Controller for PRE-Flight Flight Simulator. This free downloadable app will allow you to control PRE-Flight models without the bother of cables, configuring, or even waiting for your controller to be delivered to you.
Operate the Virtual RC Controller with your thumbs on the control pads - as you would a normal 2-stick controller. An optional, on-screen (in PRE-Flight) transmitter display shows your control stick positions. All controls are fully user-cutomizable - you can move them around the screen and even re-size them to the most comfortable configuration.
You'll quickly find that the PRE-Flight Virtual RC Controller is more accurate and faster than your old USB Controller (actual performance is dependent on your hardware specifications).
