hey, since the windtunnel is small (40cm) ill have to buy these micro plane wings:

http://www.parkzone.com/Products/Def...rodID=PKZU1080 <- this is the whole plane , this is just the wing section: http://www.wheelspinmodels.co.uk/i/62360/

you said about size of the wing...is the fact it is small going to affect lift, ignoring the wind speed. Also, the wing seems to be quite thin.
