The Zinger airplane

Step 6: Tuning it up and finishing

now test it to see how it flys and if it flys OK then your done! but if it doesn't then follow the rest of this step. so you tested it and it sucks then fold up the sides of the wing as shown and then it should fly like a charm,but if it doesn't then you can fold up the back point to make them flaps then your done!!,and if that still doesn't work tell me and ill see if I can find a cure all righty?
