heavypayload

Need some help with my heavy lift drone project! Have thought of using T motor's u15 motor, but have difficulty finding suitable components that can handle such a motor. What I'm wondering is if you have any experience matching powerful motors with suitable flight components? Which parts do you use?

I am currently planning to build a glow engine rc plane. I need help with the frame design. What airfoil shape(example: NACA 2412) would suit if i need good thrust as well as suggest me a glow engine supporting the thrust required for the frame as well. I need a payload of around 4kg or less...
