Final Assembly Steps
The model is almost ready for weight and balancing, but first lets add a couple of parts to complete it.
Glue the elevator to the Rudder as shown below. Use the centerline on the elevator to align it to the rudder. Make sure the Elevator Hinge line is to the front.
If one side of the Elevator keeps rising while the glue sets, use a small weight (I used a wood dowel as shown in the photo below) to keep it down.
Glue tailfeathers to model once they are set up.
While they are drying in position, it is ok to do the canopy rolling/gluing, getting it ready for the last construction step.
1st photo shows gluing the Elevator to the Rudder.
2nd photo shows proper alignment of tail to fuselage (AutoCAD drawing).
3rd photo shows using a piece of wood dowel to hold the elevator level while the glue sets. Notice how the rudder is supported between a tape measure and a roll of tape-holding it vertical while glue sets.
4th photo shows attaching the Tailfeathers to the model. Make sure to apply glue to the model, getting it inside the slits for the Rudder glue tabs!
5th photo shows the rolled nosecone ready for gluing.
6th photo shows the Canopy alignment lines on the nosecone/collar assembly. Use the centerline to align canopy when gluing.
7th & 8th photos show applying pressure to the canopy as the glue sets. Apply pressure to the sides as well making sure there is an airtight seal all the way around the canopy.
If there are any gaps, you will need to apply a glue fillet for aerodynamics, if the air gets under the canopy, it will cause a breaking action, and the model will drop like a rock!
9th photo shows airtight seal between canopy and nosecone.
Last 2 photos show Top & Bottom of strong/lightweight finished model!
Model is approximately:
25" long
11" wingspan
Tail is 4-3/8" Tall
Weight before balancing is 42.63 grams!
Next step is weight and balancing model for flight!
