The WM Extra I mentioned is only running an OS 1.6 and single batt pack I fail to see how you could run it any lighter without some serious design changes and theres not much to the WM Extra.
The GP Extra is heavier and I have seen it on gas just sit there and float. When it stalls it just mushes over.
The Edge will float in if you let it and thats not when it snaps.
i see what your saying but I cant believe that the case in all instances.
I have a Giant Stinger that is a porker and it has none of those bad habits doesnt matter how you fly it so some of it is wing design.
