Andrew Jesky developed this pattern biplane as a natural progression of his Acuity design. This is the smaller (62 inch wingspan) version of the design. Compared to my 62 inch Acuity this plane has more wing area, is 7 inches longer and weighs 2 lbs more. I am using the AJ motor they paired with the plane, a HobbyWing OPTO ESC, two 4S Lipos in series, and an 18×10 wood prop.
