RE: how do u install a servo on a foam wing?
If it is flat foam and you want to put it on top just use sticky pads and put tape over the top and down the sides to the wing.
Method 1:
If it is a flying wing set servo on top.
Drop line around with pen.
Cut with xacto that has tape around blade at the same height as the servo thickness.
Clear away foam inside square with small screwdriver.
Try to place servo in. The tabs will make indents on the foam.
Slice those with the blade. Slice where the wire wouldn't go in too. Slice out a part where the servo head and arm moves.
It all takes less than 2 minutes once you've done it a million times
Servo will fit snug in hole and thin clear packing tape over the top holds it in fine.
Method 2:
Use 100w soldering gun with wire bent shape of servo and bends to stop it going in too far.
Place business cards around lines and use gun.
Takes 5 seconds but awhile to get the wire setup right.
I can post pics.

RE: how do u install a servo on a foam wing?
I usually use a dremel tool with the "Multipurpose Cutting Kit" #565.
I use it like a router, it can carve all kinds of cutouts, slots, you name in in foam faster than you can think about it. I use it for servo cutouts, spar slots, fuel tank compartments, and pretty much any other time I need to cut a hole in foam. I find it's a lot faster, easier to control, and doesn't create the smell of an iron. But the foam dust created can be a bit annoying, so keep the vacume handy.
For screwing down servos, I cut in a couple of wood rails, and then cut a servo-sized hole between them, and screw on the servo. I do this on my bigger planes. It might be too much weight added for a park flyer though. I've just glued the servos in to the foam as well (after cutting the holes), it really isn't a big deal. If you need the servo back out, it's usually pretty easy to cut the glue with a long knife blade. You can also wrap the servo in making tape first, then glue it in. Then, when you remove it, you hack up the tape, and the servo comes out.

Yep, I've done the hot-melt glue thing, and it works well.
But, some hot glue will get hot enough to melt some foams. (you did say low-temp, I know). So test on some scrap foam first.
Also, in cold weather, hot melt glue can get brittle, so it's possible that a sharp jolt could jar the servo loose. I had this happen several times (flying combat, sharp jolts are more common than you're likely to experience though)
On some park flyers, the GWS contact cement glue works great for mounting servos. Someone else mentioned the double sided foam tape, I think? You can get mounting tape at the hardware store, the 3M stuff sticks really well, I've seen it take foam with it when pulling off.
