I made my own Y4 frame tricopter with help of Nora flight controller, Please help me to set the initial parameters settings. Any particular link is there to follow arudupilot?
Use this software follow it’s simple step-by-step instructions. Do not skip any step. You will learn a thing or two 
Thankyou for your reply @amilcarlucas , But my doubt is particularly in frame selection, Here in mission planner no option for Y4 Frame, So i asked arudupilot documents for reference. please tell me the frame selection parameters.
If you used the configurator you would have seen this and you would have known how to answer that particular question.
Anyway, read this and select QUAD Y4A
You are not saving time by not using the software.
