You can have some of the same "issues" with a lightly loaded 3-D plane too, CG, thrust lines, incidence,ect, you might still have to tweak a light plane. Of course I'd rather have the lighter plane too, then stall recovery would be much better, gives you more confidence to come down low to the deck, you dont need as much power & the engine has a lighter work load. But, put on enough horses in any decent 3-D plane,weight aside,it will still hover, harrier,TR,ect... Carden makes some of the heaviest giants scale planes, you should see them 3-D like crazy in videos, they have engines that can do the job, however, when it quits, thats where the difference is. Save all the weight you can, it is worth some effort, but some of the points made here are-- well---a bit excessive.
