RE: adding to elevator width??
I have noticed at the field that the lighter versions of this plane flies better. The electric one looks pretty tame, around here, but I have seen one that was a nose heavy glow and it looked like a pain. I use to fly for fun some .15 QM racers and because of the fast speed, they were flown with just a little control throw, but landing I could actually slow the plane down pretty good because of the efficiency of the airframe. I had a high rate for slow flight so I would have enough control movement; not a bunch but more than the other.
