I just Recently got a Dragon Link system

so I’ve decided to talk about what Dragon Link is and how it works since it’s what I’ll be using in all my fpv flights from now on.

So what is Dragon Link?

When you’re doing fpv (especially without a GPS) it’s nice to have good video when your flying 2 miles out, but just because your video looks good 2 miles out does not mean that your going to be able to control your aircraft that far away. That’s what Dragon Link is for. Dragon Link is a long range system that allows you to control your model from very long distances. It transmits on the 433MHz (UHF) band and has a power output of  250mW to 500mW, a normal RC transmitter made by futaba, turnigy, spectrum, hitec etc… will run on 2.4GHz at about 100mW. If you’re just getting started and you’re not going to be going over 1KM then you don’t need Dragon Link, but if you want to go 3, 6, 12 or even 15 miles away then you need a long range system like Dragon Link.

How does it work?

With radios, the lower the radio frequency is, the longer your range will be without increasing power, so even if the Dragon Link put out the same amount of power as a normal transmitter it would still be able to go farther. DL (dragon Link) works with almost any transmitter that has a removable module or a trainer port, one nice thing about is that it if you’re using the turnigy 9X like I am and you have the er9x firmware, then with DL you can turn your 8 channel radio into a 12 channel radio!

How much does it cost?

One thing that I forgot to mention is that DL is not cheap! If you’re going to buy it new, It’s going to set you back by $270 from the DL website. It comes with everything you need including antennas, mounting hardware, receiver and plugs. Extra receivers are $100 each so I would just put it in the mode your want to use for long range fpv and keep your old module for all your other models. There are cheaper UHF systems you can buy, but with Dragon Link for the most part you get what you pay for, it’s very high quality, made in the USA (If that means something to you), the online support is good, and it should last a very long time.
