Balsa Wood Plane
Back Fins
Pin the pieces of wood on there and glue it together, wait till it dries.
Wings
Same thing as before, only this time you may need to bend the wings upward with something To prop it up, glue the wheels on.
Body
This part you have to do twice and make the two parts a mirror image of the other so you don't have two sides that are exactly the same.
Glue
Glue it all together
Rubber Band
If you want it to fly then add the rubber band, put it in with a stick of wood at the end then have it hook on to the propeller.
Cover-up
For this part use Elmer's glue and glue piece by piece of the plane
Paint
Paint it however you like, just don't choose crappy paint like me.
