The JJRC Blue Crab is one of those entry-level selfie drones that sell for less than $100. It’s a foldable toy drone that has the appearance of a book when its motor arms are folded down. The name Blue Crab was probably inspired by the drone’s pincer-like prop guards.
When Quanum released the first version of its DIY FPV headset last year, entry-level FPV headsets have quickly become very popular among drone enthusiasts. Gone are the days when you had to fork out at least $300 for a pair of Fatsharks if you wanted to do some immersive FPV flying.
