This is the "Discovery" long-range frame. It is a strong redesign of the #minilongrange frame from Dave_C The goal was to design a frame that would fullfill the following conditions:

4" inch size (in my view the best compromise between size and flight characteristics

"one level design"

3s li-ion battery setup

light-weight, yet stable

I design frames for fun - each one goest through 4 phases, which are documented on Youtube. There you can also find lots more details about the frame:
