This is my attempt at the Catalina, made in the nineteen eighties ( and using the wrong shade of grey for the wings). Apart from the decals I think the kit itself remained unchanged during the many years of production.
It's a great model but the main problem is that it's a chronic tail sitter. Another snag is that the main undercarriage legs are wide, thin and a bit fragile, so they won't take too much weight. A bit of a balancing act is required, or alternatively some stronger legs.
My effort has worn well but the varnished white has started to acquire a distinctly yellow tint. I used humbrol enamels and varnish at the time. If anyone has found a good way of avoiding the yellowing I'd be glad to know.
