I have always been inspired by unique and different multi-rotor configurations. One of my favorite configurations has always been the Y4. It is similar to a tricopter but removes the complexity of a servo in favor of a fourth motor. 

The frame is cut from 2mm 3k carbon. The frame accepts up to 65mm props and has clearance for the most common whoop and toothpick style canopies. 

Specs:

Frame Type: Y4

Size: 110mm (front motors) by 100mm (front to back)

Material: 2mm 3K carbon fiber

Weight: Approximately 6.5 grams

Supports most 11xx motors with 65mm props and whoop AIO style board (25.5mmx25.5mm)
