Welcome to the exciting world of Electric Ducted Fans (EDF)! The HyperFlow is a new EDF design created by Great
Planes using the latest technology to fit onto smaller EDF airplanes. The HyperFlow was created with ease of use in mind,
as well as superior performance using either a brushed or brushless motor. Great Planes offers several different motors
that you can use to tailor the fan's performance to meet your needs. This EDF can fly airplanes as small as 10oz [280g] to
airplanes as big as 35oz [990g] depending on the chosen motor. Flying speeds can vary from 55mph [88km/h] to
approximately 90mph [140km/h]. You can now fly modern jets and fly them in a realistic manner–
fast.
