The 700X STD is upgrade version from protos max v2.It  was born from a passionate group of engineers and pilots trying to make a machine that's really something special.  We wanted something that could easily fly several hundred hard flights with nearly zero maintenance.  Something that looked stunning, but had a focused purpose for every element in the design. We wanted to create something that you can't wait to fly everyday. Without inhibition. The Protos 700X STD is a stunning feat of engineering at an incredible value.  We hope you enjoy it  as much as we do.
