Not so long ago, purchasing the ground equipment for First Person View (FPV) flying meant that you had to decide between a tripod-mounted monitor and wearable goggles. Recent developments have removed that fundamental decision. New systems, like the Fat Shark Transformer HD ($249), give you both viewing options with the same equipment. Actually, the Transformer offers three viewing possibilities. I suspect that this adaptability is the root of its name. Great test on tested.com

What is DShot1200? DShot1200 is an ESC protocol similar to DShot 600, but twice as fast with lower delay. There are some benefits in using DShot1200, and special hardware is required to run it. Just like DShot150, DShot300 and DShot600, the number “1200” in DShot1200 signifies the bit-rate in kilobits per second. So in theory DShot1200 is 2 times faster than DShot600. DShot1200 would be faster than Multishot too. Multishot has a varying signal length between 5us to 25us depends on throttle level, while DShot1200 has a constant, fixed signal length of about 13uS. Unless you fly really slow with Multishot with low throttle, it’s more likely that the delay would be between 15us to 25us (50% to 100% throttle). More on oscarliang.com
