Got mine today as well. Yeah, the wing screw heads stick up a bit. They're not recessed/counter sunk.
I just setup the mixing on my DX6i -- since it's programming is limited, I just setup the Flap switch for the "launch" mode with the landing position setup with a down 30 value, which translates to about a 1-2 deg down elevator just by eyeballing it.
I also mixed (mixer 1) the aileron with the throttle so that a max throttle, there's also about 1-2 deg of right rudder, and that mix is activated by the flap switch. This way, my launch setting is: max throttle, flap switch down (landing). When I flick the flap switch back to normal, the control surfaces go to neutral.
Not sure how this will work out, but it's the best I can do on the DX6i, and this is really my first hand launched glider, so we'll see when I get back from the field...
PS: I basically set it up based on Matt Andren's RCG post on how he set it up for the DX8:

I hope I didn't go overboard with the mixing. His advice is to start low, and go higher.
