I just acquired an old EPO plane that I would like to spackle, sand and paint to try for a smooth finish. Doing this just for a fun challenge, and my goal is to make this plane look like it's not a foamie. I'd love some input.

What would you suggest I do to get the plane smooth for painting; some sort of spackle that will not crack and fall off?

I bought some Horizon Hobby Woodland Scenics Foam Putty and plan to spread it on the EPO foam, then sand it smooth.

The reason that's not done more frequently is weight. That plane is going to weigh a ton when you get done, and will have lost all of it's low speed maneuverability.

If you want to try this, DON'T try it on a plane that you like!

There's actually stuff specifically made for putting a smooth coat on a foam surface. Damned if I can remember what it's called. I have a bottle in my workshop. It's some silly name. I bought it at a local "Michaels" generic-hobby store. Works pretty good. Retains a little flexibility so it doesn't crack like spackle would.

Good advice, thank you.

Beacon makes a product called Foam Tac foam finish which I have never used, but sounds like exactly what you are looking for.

The same applies to all flying machines, even 1:1 scale.
