RE: Strap it or screw it on?
As minnFlyer said, set it up for both ways now, but I would reccomend using rubber bands while you are on the uphill side of your learning curve. The trick is to use enough bands, but not so many that you remove the reason for using them in the first place. There will be plenty of time for solid mounting of the wings later on, but right now the name of the game is being able to fly it again. Hope this helps.
