I just bought new Yuneec Skyview goggles from Ebay. I was able to get them for only $40.00 shipping included. I have a Samsung Galaxy S10e with a usb c to hdmi adapter. It works great and is extremely clear. It's quite a new experience flying my spark fpv. Having spotter is a must. Just wanted to share that the price of the goggles have really made it affordable for the spark.
