Issue with applying custom mixer

I’m creating a custom mixer and airframe for a fixed-wing aircraft with distributed propulsion along the wing. Firmware compiles without error and I’ve been uploading it using QGC. The airframe seems to show up in the standard plane group. However, when I select it and apply the change the original airframe is selected in the airframes tab again. Is this a UI issue or is my airframe not properly applying?

Hi @kylelambert

To my knowledge the easiest to check if the custom airframe is applied in the firmware is to check the SYS_AUTOSTARTparameter that is saved on the autopilot. If it corresponds to the value of your custom airframe then your airframe should be properly applied and it’s just a UI issue
