Yes, but a driver’s license is hard to get, and even if you spend a few hundred thousand dollars to get one, the ATC seems to have a limit. You can always find a reason to stop, and if you get permission, you can fly low.
Is cheap, below 100 w can fix (small 50 w is actually about the same), maintenance is not difficult, as long as had managed to airlines, but basically buy is a pile of scrap metal, because there is no open low in our country, where you have to apply for, let alone the cost, first is the high rate of examination and approval, however, even if passed, is not only to spend a lot of money,
And most of it is a month or two later, trouble to death!
