I saw that thread. He is doing a great job there, looking forward to seeing the end result.

I thought of trying the 3D printer avenue for this plane but I ended up going down the foam path (except for some parts) due to the following:
- Localfiend is doing it
- it would take me 10 times longer (not that good with Fusion 360 yet... getting there but a plane like this is a major design job)
- i'm still not convinced that plastic would be any better than foam weight-wise and sturdiness-wise

I started doing some pieces like wheel pants, pilots and scale details (radial engines, struts, etc) in plastic and found their weight is significantly more than foam counterparts every time (they look a lot better though).

Also, one of the best things with foam is that you can restore its shape with hot water, glue it back together, and get away with a minor paint touch up.
Plastic on the other hand will crack or shatter making it harder to repair. Fair enough you just print it again... but the hardest/longest part in building planes for me is not the build (I can typically build and glue everything in a week or two), it is the paint job!

Anyway I reckon I'll try it with a simpler build soon (got my eye on a YAK 54)

Looks beautiful Mario!
I agree with you about using foam as the medium. Plastic just isn't as forgiving. It's a great medium for a static model or certain detailed parts but in saying that I'm sure his plane will fly just fine. Most probably like how a balsa plane performs.

Looking good. The Bulldog is a great subject.
One of the RC magazines had a plan as a pullout around 12 months ago. I almost bought it for the plan but didn't. Kicking myself now.

Looking forward to seeing yours finished.

Paint job complete.
Next step is WBPU protective coating and decals.
I'm pleased to see it's coming together just fine

What AUW and wing loading do you think it will be?
