Avro 504 N/O 1/20th scale electric

a formed piece was glued on the inside, as a base for the cover, also shown in rough form

and the total nose put together for some more photographs

and the right side, this time without visible flaws.

The dummy propeller fits into the crankcase hole.

As I was writing at the time, when posting in the old HPA, I was begining to question how far was too far, in terms of detailing.

Making the strut end plates was a new one to me, especially since they would be functional stress taking parts.

Some CAD work to define the hole positions and a plywood jig for the starting holes of 0,5mm

[g_kandylakis]

mass production...

8 wing struts, 4 cabane struts, 12 in total, 2 ends, so 24 final parts needed.

[g_kandylakis]

drilling to final diameters, done by hand for each hole, in 0,1mm increments.

Some flattening and rough cutting

[g_kandylakis]

and sanding to shape, using tube guides for all the rounded edges. Jeweller's work...

[g_kandylakis]

back to some normal aeromodelling... Covering...

A simple base was made to hold the wings steady while covering the lower side.

[g_kandylakis]

Dope and thinners, using a thin piece of balsa to apply uniform pressure to the area being glued.

[g_kandylakis]

trimming the bottom side edges

[g_kandylakis]

top side follows.

Pre-shrunk tissue used everywhere, makes the task much easier.

[g_kandylakis]

and some finished wings

[g_kandylakis]

tissue shrinking, a simple base to allow full ventilation

By George,George!
I'm impressed beyond words by your meticulousness, patience and capacity to take pains!
I will have to lift my game, to be worthy of contributing to HPA!

[Prosper]

I'm glad you're re-posting this immaculate build, George - for purely selfish reasons: I want to be reminded of how you made the rib tapes with stitching .
