My brother has flown one of these on a tether. They are deafeningly loud and put out tons of heat so you need special clothing and it needs to be cool downed after use. Have to fly low to the ground or over water where you are better off with other means of transportation. Not to mention this thing runs out of kerosene in 10 minutes. Not practical for consumers in the slightest.
