Fuselage, part 1

Before setting out to build the fuselage I decided to do some planning and lots of reading. My Chicken Hawk will be powered by an electric motor so I had to make some changes to the fuselage in order to accommodate a battery, an ESC, and a different motor form factor. The plans also depict a control mechanism that I will replace with two 9 gram servos and a receiver. Because I don't have access to the plans of the modern kit, my only option was to closely examine picture on various build logs and articles, as well as draft some ideas before starting to cut any balsa.

My modifications were simple. I replaced the bottom covering between former F1 and F3 with a hatch and an opening for the battery. I also refashioned former F2 with a larger opening. Moving former F1 forward by 3/4" gave me more space for the electronics and eliminated the need for any extension to the motor backing.

Heeding the advice of others, I was very careful marking and cutting the fuselage sides. I used two 4" wide 1/16" thick stock, and taped them together with double sided tape, then taped the edges together.



I marked the fuselage outer lines using a technique I used way back when I first started this hobby. I use a pin glues to the end of a dowel. With the plans firmly held to the balsa sheet I mark the lines with the sharp end of the pin, tight curves with more points and long lined with fewer jabs. Once done I trace everything with a straight edge or curve ruler.



Both sides cut and perfectly matching.


The build article posted with the plans on Outerzone has some practical tips on how to build the fuselage. I followed the recommendation to start with former F5 then proceed with F3, F4, F2, and F1. Finally do formers F6, F7, and F8.

Covering

Image
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...

Top wing

Image
I started with building the top wing then the bottom wing, and included some picture and comments as I progressed with this first step. I followed the exact same process when building the bottom wing. For each wing I traced and cut the set of four LE and four TE sheeting according templates. I made the templates out of packaging cardboard. The top-wing templates are visible in top right of this picture. The bottom sheeting (3 pieces) of each wing panel include the LE, TE, and wing root sheet that I glued together to form a single piece.  Closeup of magnets holding 1/16" balsa sheeting. Spar and ribs. Left wing with-top sheeting attached with clothes pins. The top sheeting was glued in three stages: TE then LE, and finally wing tip. I used water to dampen the the top sheet, mainly LE and wing tip, to help form and curve the sheet to the ribs. The plans call for the top sheeting to have the same dimensions as the bottom sheeting. I found that if I extended the overall width by 1/8...

Electric power and controls

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...
