Chicken Hawk, 3ch RC biplane

I set my target AUW of 453.6 grams, or 16 ounces, for the Chicken Hawk according to a build article I read on the February issue of Model Aviation. The article was written by Bob Benjamin and described his impressions of the Chicken Hawk kit available from Retro RC. By sticking to the original plans posted on Outerzone I managed to achieve an AUW of 416 grams or 14.7 ounces. This weight gives might give a bit of a margin to use slightly higher capacity LiPo batteries. The power plant I am using includes an E-MAX CF2822 1200Kv motor, with a 30A ESC (slightly over-sized), driving an 8x6 propeller. The measured power draw is just over 9 Amps, which yields about 52 Watts. The overall power to weight ratio is between 57 Watts/Lb, which seems more than sufficient to drive the Chicken Hawk. Wing loading is 8.95 ounces per square foot, and Cubic Wing Load is 7.0. I have a similar weight and wing span foam plane with the same power plant, which also gives me a good idea of the expected fight ch

Fuselage The fuselage received two coats of Sanding Sealer with light sanding using a 400 grit paper before each coat . After the first two coats I applied the orange Silk Span trim patterns. I wet the orange Silk Span with water from a spray bottle, positioned it carefully, and removed any trapped air bubbles. Once satisfied, I applied Sanding Sealer to the orange Silk Span to fix it in place. When dry, I ran another light sanding of the entire fuselage and applied the final coat of Sealer. Battery compartment cover. I added a "CH"emblem on the right side of the fuselage made out of black iron-on covering. I printed a template with the size and font I wanted and cut the lettering with a sharp hobby knife. Wings I followed the test covering process I did on the balsa frame and covered the wings with clear (white) Silk Span. Once the edges where dry, I followed with light sanding and a coat of Sealer. I added the orange color trim following the 1963 patterns. Just like the fus
