If you choose to fly your Micro Owl as a glider without a motor, your owl will weight only 14 grams, perfect for that gentle ridge lift and slope gliding, slope soaring, even on a shallow embankment she will take flight with ease. Using a 5 inch propeller coupled with a micro 2gram 50000Rpm geared motor which provides unlimited vertical climb on a 1s 100 to 150mah li-po battery. Perfect for close proximity flying ( backyard flying ) with over 10 minutes of joyous flight time on a single battery charge. Virtually indestructible due to its light weight and carbon fiber reinforcement, the Micro Owl design is based on the owls airfoil development with large wing area resulting in low wing loading and a low aspect ratio, which contributes to maximum air time allowing slow graceful flight. Ultralight weight of 24 grams, Micro Owl is laser cut using contest balsa wood and carbon fiber for structural strength. Studying Barn Owls for many years and their graceful slow flying characteristics has lead my passion and love of owls into designing the Micro Owl. Taking elegant ultraslow flights with the Micro Owl is truly a peaceful experience.

Climb high, cut throttle and enjoy an ultra slow glide back to earth with full control. Full throttle input will accelerate the owl sky high with virtually unlimited vertical climb. With over 10 minutes of flight on a single battery charge providing only 1/4th throttle for flight, the micro owls design truly flies with little effort with incredible slow speeds. When your wing has a higher camber, it also has a higher lift coefficient, meaning it can produce more lift at a given angle-of-attack.Īlthough we cannot mimic such dynamic wing articulation in flight with radio control airplanes, the integration of the owls airfoil has been successfully achieved with the design of the Micro Owl. With such massive under chamber airfoil design, the wings act similar to flaps on an aircraft. Owls in comparison to other raptors have large wings relative to their body mass and thicker airfoil with massive under chamber along the inner root chord ( greater and median secondary coverts), which allows them to fly unusually slowly.

With massive under camber and wing area, the owl like airfoil has high lift performance with a nonlinear lift increase due to the presence of a separation bubble on the suction side. The wing geometry of owls in particular is characterized by complex variation in parameters such as camber, twist, sweep and dihedral. ( flowstate)īirds of prey primarily control flight by pivoting and articulating the shape and direction of their wings and tail.
Micro Owl offers just this, providing an ultra slow and graceful flight giving you that space between you and your body, between you and your mind. To walk a Zen path is to do everything with grace. Translating nature’s strategies into design resulting in maximum air time with slow graceful long flights.
