Hi!
Rubber mounted wing is much better for a newbie!
In a crash the wing will get lose and hopefully will not destroy anything.
The only modification you have to do is drill holes in the fuselage for two 6 or 8mm dowels and glue them in.
In the pictures below you can see the dowels, in this case they are 6mm "Easton" arrow shafts, and let them protrude at least 3cm out from the fuselage on each side. Use at least six rubber bands!
