The mix of different planes here is not surprising, whatever you do save weight wherever possible.

The biggest enemy of a good hovering plane is weight. I flew a .25 size 3Der for a while with a .40 and standard equip. I did another of the same plane with a hot and light .25 and light equip doing everything to save weight. The second plane was 9 oz. lighter. The second plane flew and hovered 100000 times better than the heavy one!!!! After a few flights I was backing it down in the hover to exactly the height I wanted!

Keep it light!
