What a rude small minded person you are Krash. Just plain rude. Dont come back to the forum if you cant handle the responses YOU ask for. Omg what a tosser!! Maybe too much time spent "sloppin out the hogs" mate.I can see it is a waste of time using this forum. The hogs don't need slopped for a few minutes so here goes. Riddle me this Splatt man. If the Karma is so perfect why is it no longer being produced? With such stellar engineering bordering on perfection why have there been so many Karma's fly off's? "Quality and performance stands out a mile" ??? Fly's out a mile is more accurate! Are you a paid shill or an employee of GoPro kissing up to management?
Free thrust. Ducted fans are constructed so that the fan housing is a lifting body on its own. Air flow over the duct surfaces produce lift and is in addition to the lift produced by the prop.
Krash, over and OUT!
