Unless you have enough elevator to cause the plane to not loop successfully anymore (with full ele, it should try to roll out of a loop, or do a polygonal loop (stall, catch, stall, catch) then there's not enough elevator. If the plane's well built, there should be no worry about damaging the wing, though this manouver can expose inadequate construction.... Sounds like you've got piles of rudder available.

Some aircraft may benefit from a bit of aileron, but it's not generally required. Can't hurt to try . I'm performing them with a .25 powered high wing flat bottom 3 channel trainer, rudder/ele only. When I apply full up elevator, it's loops begin to show alot of roll tendancy, as my elevator throw is excessive... About 35 degrees. It's the Aamco (Andrews) S-ray shown in my profile, a heavily bashed version of a trainer kit marketed in the late '60's, about as gentle a flier as you could ask for.... Unless you force it to snap!

Remember, though, this is a high-stress, violent manouver involving abruptly stalling one wing panel, and the craft will rotate 3-4 times quicker than it can with just aileron. There is no guarantee (ever) that your plane will survive (99%+ will survive )
