Fuselage Construction - Continued

>> Back to Page 1

Well, I guess not totally completed.. Here I added the wing hold down block, which I tapped with a 1/4 thred and used THIN CA to harden.

Fuselage is completed!  Once sanded it looks great.  Spent about 4 hours to complete.

Added triangle stock to beef up the firewall, and added the floor for the fuel tank.

The fuse is completed, but a little rough, needs sanding.

Next I worked on the "tail feathers" on the plane.  The leading edge of the vertical stabilzer, horizontal stabilizer, and trailing edge of the rudder were sanded round.  I did that by cutting a 1/2" piece of PVC pipe down the middle, and glueing in a piece of 100 and 220 grit sandpaper.  Worked great.  Then I notched out and drilled holes into the two elevators, to epoxy in the music wire that joined them together.  I also notched out and drilled a hole into the bottom of the rudder to attach the tail wheel arm.  I used CA and fiberglass tape to make sure it will not come out.  Finally, I sanded the leading edge of the elevator, so it was beveled and could move freely once hinged.

Getting closer, I need to glue in the control rod tubes to the fuselage, they were later trimmed flush with the side of the fuselage

More Wing Construction

Thought I was done with the wing - not quite.  I had to drill the holes to attach the wing to the hold down block - for the nylon bolts

Next I drilled the hole and epoxied in the 1/4" dowel that holds the wind into the airframe.

Sig also recommends that you use fiberglass tape on the wing joint.  First I tacked down the tape with spray adhesive, then soaked it with thin CA.  Then sanded furioursly for a smooth finish.

Here is one deviation from the kit - CAPSTRIPS on the ribs, which were recommended in the Covering RC Airplanes book I just bought.

COVERING

This is me holding my newly covered wing.  I am using a read and black trim scheme with red/white checkerboard trim.  I am using Hangar 9 Ultra Cote and Easy Cote.    Here are some shots of the covering process thus far.

See the final photos on it's maiden flight on 8/13/05!
