Know what looks really crappy? a 400 dollar bag of splintered balsa A trainer that you've put together yourself takes on a most beautiful sheen-especially when the baby takes off flies and lands-all in one piece! like the others said, cover in a fun way that pleases you. Sometimes you can do somethings with balsa to enclose the cowl for a scale effect. If it has wndows, and a pilot figure, or tint them. Build in a bit less dihedral if the kit shows an obscenely unscale like amount. ps the aerostar is kind of good looking for a trainer and flys nice. PPS if you make mods to your trainer kit make sure that proper cg is maintained.
