I really don't like to knock Estes products but I have to make an exception with the skywinder. It's really not a very good representation of one of the most interesting recovery types in model rocketry, the Helicopter recovery model. unfortunately it's proven pretty unreliable and from much observation of many skywinder flights very easily damages. It's also a tail rotor configuration which is opposite of just about every HD model flying
If it's the only HD model you have handy I guess it beats a blank but it would be much more fitting for your exhibit to show a Rotoroc or Rose-a-roc type model. A little more difficult to build but not really anything all that special.
Fliskits has an excellent "Kit" rose-a-Roc out currently (there are a bear to build however). Rotoroc plans are available just about everywhere. If you need one let me know I should be able to forward something if needed. The Tasmanian Devil is another option in a fixed rotor type HD "qualifier" type. and there are a number of other "Maple seed" type Helicopter recovery types that could be shown.
Here are a few examples that may spark interest. If you do finish your Skywinder, I'd keep it as a static display model
