Whippet I/H Frame: Parts, Build Review, Tuning, LOS, & FPV!

The Whippet I/H Frame from Detroit Multirotor is probably the best thought-out frame I've seen. Every component seems to have its place and fits easily on the body. The "stretched X" (or "H") shape makes its pitch/elevator feel much more in-control and makes this quad look different than most of its competitors. The LOS flying is a different experience too. It rolls more quickly than it flips.
