Step 1: Back Fins
Pin the pieces of wood on there and glue it together, wait till it dries.
Step 2: 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.
Step 3: 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.
Step 4: Glue
Glue it all together
Step 5: 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.
Step 6: Cover-up
For this part use Elmer's glue and glue piece by piece of the plane
Step 7: Paint
Paint it however you like, just don't choose crappy paint like me.
