Review: Hitec Spectra AFHSS 2.4GHz receiver and Optima 7 module (part 1)
Part 1: a first-look at the Hitec Spectra 2.4GHz AFHSS spread spectrum system from Hitec.
This video gives a quick overview and asks why Hitec's system only uses about half of the available 2.4GHz band, while others such as Futaba FASST use the entire band.
See part 2 for a demonstration of the "scan mode" and how it can effectively sidestep other signals on the 2.4GHz band, such as video transmitters. This might make the system perfect for those who enjoy FPV flying.
