I also noticed in the video that they had hearing protection but it was on the ground next to the fire extinguisher. Reading the very nice detailed instruction manual[1]: To the avoid hearing damage, always use hearing protection when you are near a running turbine engine! Along with a couple warnings: A flying model with a turbine can reach higher flight speeds than ducted fan-powered models, because the turbine’s thrust degrades less with higher flight speeds. With attainable flight speeds of over 250 MPH, you can quickly run out if flying room. There is also a danger of developing control surface flutter or mechanical overload, causing the model to fail in flight. That said with a list price of $4,195.00 just for the engine I have to imagine it'll be a while before we see 100's of these in the air at random parks.
