Title: Convair 58-9

Giving this a shot.

Settled on 1/200 airliner scale. Hopefully haven't bitten of more than I can chew, but we'll see.

Also if motivation strikes I'd like to build the shorter rc-80 alongside and maybe a 1/350 scale on as well.

The double fine on the outboard engine gives it a Thunderbirds vibe. 😎

One weeks worth of anti-procrastination:

Minor revision. I left a tab on the main cross section to help align the tail fin, but realized it made shaping and sanding the rear fuselage difficult. So just had to cut a chunk out and invert it and will now have the tab on the fin itself.

Productive week.

Started with the engines. These engines have flat sides and a bulge on top and bottom, thought I'd try using 2 half pipes:
(https://live.staticflickr.com/65535/48073316887_092f618053_m.jpg) (https://flic.kr/p/2gf5jga)Untitled (https://flic.kr/p/2gf5jga) by BTSpolygon (https://www.flickr.com/photos/159490316@N06/), on Flickr

That ended up not working too great so had to fall back to plastic frame + putty:

Better, but then I dropped that and broke the bee stinger exhaust and had to re-do the whole thing again - leaving the core out until the last setp:

Turned out much better:
(https://live.staticflickr.com/65535/48073260783_9062cd9e74_m.jpg) (https://flic.kr/p/2gf52zR)Untitled (https://flic.kr/p/2gf52zR) by BTSpolygon (https://www.flickr.com/photos/159490316@N06/), on Flickr

Not willing to do that 3 more times so I turned to good old resin casting. Using something called oyumaru - it gets soft in boiling water and can be reused afterwards. It's perfect because I only need 4 engines, I'll keep the master somewhere and re-use the oyumaru later:

Lego to the rescue again:

Not perfect, but a bit of sanding and it'll be alright:

Hope to have it ready for paint by the end of the week.

Gotta start thinking about colour scheme now, I'm thinking Eastern Airlines maybe Delta - I don't know much about 1970's airlines.

Beautifully cast engines, BOAC livery would look good.

Great work!

How about Air Canada? CF-SST.

Lookin' great so far.   :smiley:

Particularly like the way you're doing the engines. Might be an option for one of my own bilds. What type of putty did you use?

I use Tamiya Epoxy Putty (Quick Type), I've tried others but I like this one the most.

Great suggestions - still cant decide though.
I think I will just leave it to an informal poll, if anybody would like to cast a vote or offer a suggestion post it here in the next say 24 hours.
So far we have:
Air Canada
BOAC
Eastern
Delta

If no clear winner I will devise a way to randomly pick one.

This is looking really cool,

I agree with kericks comments, it really has a Thunderbirds/Fireflash vibe to it.

Look forward to the final reveal

I have to try the "oyumaru with Lego casting frame" trick. Thanks for sharing!
