Ok, completed phase three build.
Short acceleration run in kitchen shows it has power.
Double 3/16" rubber bands give it some go power. Still need to weight and balance for flight, but looking good so far.
Finished weight before weight and balance: 4.3 oz so big time heavy weight, but the 9.5" prop does move it good.
Inside fuselage look at balsa wing and fuselage support 1/16" thick supports. Four pieces create a "box" to handle flight loads:
Attaching Wing Skins. Just slide on and then insert tabs into fuselage before gluing along entire length with fuselage wing. This creates a fillet glue joint on top to give it strength and helps with airflow:
All three of the builds so far. The paper one is not going to last long, any handling and it just caves in:
Here is a close shot of the 30" Wingspan 4.3oz bird:
Well, have other projects to do. Did order a roll of tracing paper to see how it will work.
Might need an electric motor to get this one in the air after weight and balance....Going to be HEAVY!
