Code 43 is just telling you that there is a driver that is not working correctly. Right click on the device in the device manager and click uninstall and remove that driver. Then, click on the articles tab at the top of this forum, then on 3GX and download 3.1. Install the software and make sure to install the drivers after the program installs. Also, make sure your USB dongle is NOT plugged in during all of this. Once the program and driver is installed, turn on the Tx, turn on the heli, wait for it to initialize then plug it into the computer. This should correct any issues.
