Additional framing will allow the cap strips to create the airfoil shape

Wingtip gets raised 1/16" to add wahout and help with curved tip tissue covering.

The Delfin is as finished as it's going to get. There are several more details that could have been added, but I decided not to. I'm hoping it still performs without them .
 
4.13.08:
The upper wing and cowl ring have been attached. The cabane struts are next.
 
4.02.08:
Aded photo of engine 'graphic' to be used in place of built up engine.
 
3.30.08:
Covering begins. The scheme I'm showing repressents those used during the Spanish Revolution. Red strips of tissue are glued to the  adjacent piece with an overlap of 1/16".
 
3.25.08:
Mock up of wings and struts.
 
3.23.08:
Engine cowl is added (temporary so covering of fuselage can be completed), an cap strips for the tail feathers has beed added and sanded to shape.
 
3.21.08:
The main framework is complete and sanded. Next is adding cap strips to the tail feathers, and building the engine cowl from built up balsa rings.
 
3.13.08:
Stringers added to fuselage. Underside 'chin' stringers are balsa strips 'rolled'  into a curve by passing a round pen barrel along the length producing a 'built-in' curve.
 
3.09.08:
Fuselage box complete, stringers are being added.
 
3.06.08:
Fuselage frame begins
 
3.02.08:
Built upper wing
 
3.01.08:
was able to work on the upper wing and rudder. Cap strips need to be added , and the center section of the wing has been built also - just no photos yet.

I'm scratch building this project from Michael Heinrich plans - enlarged from 16" span to 1/24 scale, i.e. 17.25" span. Because of the larger size, I've chosen to add cap strips to the top and bottom stab to provide an airfoil shape. To do this, I needed to add additional stick framing to the stab so there was enough structure to hold the airfoil shape once complete. You can also see that instead of using single curved outline shapes as called for on the plans, I've 'chased around' the outline with strip stock. The final outline will be sanded to shape. It's certainly not as pretty as the drawing, but it's quick.
