Futaba T8J vs. 7C

[Zachary]

I am building a DJI F450 with naza m lite with gps. I plan to do fpv and add a gopro camera. I want to do long distance flying in the long run. Which radio would be better suited and what is the better system the FASST and the FHSSA? PLEASE SOMEONE WITH experience please help? Thank you so much Zachary
