This AMD is a knock-off of JHH's Hawk. AMD is selling the Hawk and uses Larry Wolfe and Jet Hangar's name without paying Larry a penny.
This sounds like an assumption...I know, I used to think this way too.
However, the following was pointed out from the JHH web site:
The Jet Hangar Hobbies/AMD 1182 Hawk is the world's first .45-.48 size ducted fan
The whole slituation is pretty confusing for consumers. A lot of us don't really want to support intelectual theft, but there may be original designed and built Hawks being thrown under the "clone" umbrella" when they shouldn't be. But then again, maybe not.........
