I don't have the Alien tech, but I do have the 4Hawks SR and I have traveled 3 miles out one way, without one dropped frame! Absolute Rock solid connection! I I could have gone much further, but I am not into distance flying and just wanted to experience firsthand on the reliability. I need a signal that will penetrate through the noise of a urban area, or any uncommonalities along the way. The 4Hawks are not powered/amplified, whereas Alien tech are. You can get two different styles of the Alien...2.4 and 2.4 - 5. If I was going to purchase them I would purchase the Dual band for future purchase proof use. Just a thought. Correct me if I'm wrong guys, but I think 4Hawks and Alien are about $100 apart.?You will definitely get stronger penetration and longer distance with amplified signals. I cannot truly speak to using the alien Tech but have read and seen many articles and videos. Both products are great! Anyone in this hobby/profession will tell you, it's not about what products you buy, it's about what you use it for. I haven't tried a soil tiller behind a tractor to cut the greens on a golf course just yet, and, although it might work, ? I'm not sure it would work as well as the product designed for golf courses specifically. If you've got the money and really want them, go for the alien Tech. Once you modify the controller, and need it for quick flights without hooking the alien Tech up, you can throw some whip antennas on. They have both styles, quick connect and screw-ons. Waldo-Pepper was ever so kind as to help me all of them and to understand them a bit. (?KUDOS!?) I amazed myself the other day after installing the .18 firmware. I took it outside for a quick test flight and after all the calibrations and launching it and doing a hover inspection, and to my pleasant surprise, I flew out almost 900 ft away from me before I realized I had no antennas nor the range extender connected to the remote! ?. All of a sudden I lost connection. I was confident in the ability that it would RTH, which it did flawlessly. I did find that with stock antennas I was not able to even achieve 2,000 ft. In an environment which I would normally fly in. That was my choice for getting this type of product. Hope any of this helps.
