The Starfire looks like it would be a fast flyer, but hard to say... One of my favorite planes is an old Hobbico Avistar of about the same vintage, and it's a great flying plane. I don't really know anything about the Starfire. I think that Hobbico makes some decent planes, but I have no specific knowledge of the Starfire...
The Cub, will fly like a Cub. What is the wingspan on the Cub? The EA-50 might haul it around if it's less than 80" span. I am a huge Cub fan, so that would probably be the first one I would put in the air.
What size is the webra?
Be sure to check and double check all the control surfaces, and plastic bits. My Avistar had some brittle control horns, and when the elevator horn broke in flight, it was a bad day....
I'd probably toss the old radio and fly them with 2.4. I am sure the radio batteries are no good at all.
