I chose the one that included a typical remote control. Then I attached external antennae to the remote and purchased additional (for the time being, they are simply sitting there). I added RHE firmware to extend the range; I was able to fly up to 1000 m with it, but only 300 m without it before losing FPV. I suggest getting an extra battery for the remote control and computer. For some reason, they suggest HRB: Because the battery charge lasts 2 to 5 hours, and add, it is unnecessary to wait until World Shopping Day, November 22, when prices are significantly reduced. You can prevent the scenario where the remotecomntrol is empty while you are out in the field with charged batteries thanks to the battery in the remote control. Such a battery was taken by me; it is typical but a little bit thinner and easily fits into the computer. When using fake batteries in place of the original x3 cells, the calculator can only fly for a maximum of 15 minutes rather than 20. The conventional remote control is good; it fits comfortably in your hands and has a loop so that you can hang it around your neck with a string. In comparison to the pro version, the screen is bigger on the regular remote. In order to avoid crashing the computer and to prevent it from taking off on its own in an uncharted direction, you will need to dive deep into a few intricacies. If you are a novice buyer, it is best to look at new eBay and make sure before purchasing given the abundance of offers on computers for sale there.
