We presume that the Aerobat will bebuilt byexperienced
modelers but due toitssimplerapidconstruction,the
Aerobat may appeal to less experiencedmodelers as well

Onesix-footroll will beenough to coverthe Aerobat,but if
you wish to add trim colors or other designs, you will have
to purchase more than just one roll

dust as possible leftfromsanding the model This can be
done with compressed air,a vacuum cleaner, a brush or a
tack cloth.
Now the Aerobat 40 wing and tail feathers are ready
