Anyone here care to explain why my spark keeps on disconnecting? Wherever the camera is live it is laggy and is delayed. Not enjoying the product so far.

This is getting out of hand. The "not image transmission signal" is literally popping up every 4 sec

Have you checked the antenna positions, are you always directing the RC towards the Spark and is there a direct line of sight or are obstacles in between? Or are you flying in an area with many other WiFi networks?

FPV video latency?

What device are you using? IOS  or Android?

iOS. I calibrated the IMU and it worked last time but now it is a permanent problem. Is there a way for me to send this in? Or return

It is now just a quadcopter with no camera.
