First of all a "HEAD" is not a pilot. Neither is a "SHOULDER + HEAD" glued to a flat surface under a plastic canope. I'd rather leave the "pilot" out entirely and say it's being flown by "SPACE GHOST" or the "FLYING DUTCHMAN."

I think the question was originally addressed to finding a really scale looking pilot. For starters you can't really have a good looking pilot without at least the semblance of a cockpit. For example, the pilot figure should extend below the depth visible from the outside. The next thing is to realize that a good looking pilot is almost as much of a task and any other part of your scale finishing job. You wouldn't expect to be able to paint and weather your gorqeous warbird in an afternoon, so why imagine that you can do up a pilot figure in 10 minutes. Here's what it really takes:

An easy way out (well sort of easy) if you happen to be building at around 1/6 scale is the excellent "GI JOE SCALE" figures by Elite Forces. For example, this American WWII pilot.

Naturally, these are too heavy for most RC planes so they will need to be stripped down. For my Fokker EIII, I started with the Luftwaffer Pilot (looked the most Germanic) and kept only the head, gloved hands, leather jacket (with modifications), flying helmet and goggles. Then I stuffed it with cotton and put some wires in. And put my Rx battery in the chest area with the wire exiting through the jacket sleeve. Then if I were as artistic as Tom (NEO), which I'm not by a loooooong shot, I could have done something along the lines of the following:

In the end, my pilot looks pretty good unless you look straight down 'cause then you realize he has no legs -- there just isn't any room for them. The way I've got things worked out, the pilot even moves slightly when I move the rudder and elevator.

In short, if you're just flying a fun-fly plane, who cares if you have a pilot figure or whether you use a troll doll with pink hair. But if you aspire to have a "serious" scale plane then you should spend as much time on the pilot as you do on the dummy engine or landing gear doors.
