This is a troubleshooting video for those who have problems setting up. Cheers!

WARNING: BEFORE YOU USE FOR YOUR NORMAL QUAD, YOU NEED TO RESET THE TRANSMITTER. I DO IT BY TAKING THE BATTERIES OUT AND LEAVE IT FOR FEW MINUTES.

Brief instructions:
1. Plug one end of the audio cable (stereo/mono) into the back of the transmitter and the other end to the "Microphone" port of the PC. *** It will not work if the audio is plugged into the Headphone port of the PC.
2. Go to start on the lower left corner of the screen. Click and type in "sound" in the search bar. Select "sound" in the search results. It will open up the 'sound" menu box. Under the "playback" tab, double click on "speakers" and the "speakers properties" menu box will appear. Go to the "levels" tab and move the slider to the left to make the value around 40 or to whatever value that is applicable to your case until you get a stable connection with SmartpropoPlus and it detects all the channels. (Of course before this, you need to connect your audio cable and switch on the transmitter with SmartpropoPlus open.
3. After this, open FPV Freerider and calibrate the transmitter as normal and it should work now.

This is a good simulator. You will be able to improve your LOS, Acro and FPV skills. Please go get one to support the developer.
