I have a hacked Flysky gt3c that is great. I want to expand the usable channels now that I am more familiar with it but have run into a problem. I thought the firmware allowed for 8 usable channels, but I am unable to assign channel 7 or 8. The firmware only allows me to assign up to 6 channels which are already used. I have 8 channels set in the global setup, but only 6 show if I try to assign a specific button to a task. Is the firmware limited to 6 usable channels?I know how to set them, if I can find them, just need to know if they are there. Thanks to anyone who can help.
