Sounds silly doesn't it? The top of the unit has some decent real estate. The parachute won't block the GPS antenna assuming it won't be made of metal. I'm only tossing this in the air... Hypothetically, a deployment parachute triggered based on these events would be nice: Low zero battery warning if greater than a certain height (say 5 feet, gimbal arm tolerance). Hard impact (like an airbag, if acceleration is this and deceleration is this, please deploy). Loss control from prop damage or loss (say the IMU cannot balance fix itself for greater than 3 seconds). Little warning appears on the FPV. Turn on "find my phantom". Happy customer I guess DJI have more on their plate..
