so I bought the 2.4 and 5.8 Sunhans amps and I run them on my P3S in quite satisfied with the performance when paired with my DBS antenna. I got 13,000+ feet with this setup through 1500 feet of land and lots of houses/ wifi networks then the next 11,000+ feet over the ocean before I lost video and initiated RTH. Just wondering, how much am I leaving on the table because I did not buy the gold Sunhans amps? I know nobody can give me a feet I could expect answer; but my question is, just how much better are the golds? And are they worth it?
