A First Answer to the Challenge
Solo,
Here are three very basic, easily-buildable single-engine designs that meet your criteria. They are all ST-10 size models, which means they should have a nice "feel" in their hands. Not too small, like a BT-20 or ST-7 design, and not too large, like a BT-55 or ST-13 design. All of these use a standard 36" x 1/8" rod for launch.
The fin pattern is slightly modified from what RockSim offered. They are larger, and they are 1/8" thick balsa. That should also be a plus for small fingers, in that it has a bit more ruggedness when being handled.
