Obviously you either havent flown aerobatics much or you have never taken the time to set them up correctly. A properly set up Extra is one of the easiest airplanes to fly. If you doubt that then I suggest you download the current IMAC unlimited sequence and imagine trying to fly it with an airplane that is difficult to fly. The only difference between a trainer and this sort of airplane is that an Extra has no self righting tendencies, it will go where pointed but is very predictable and forgiving. The fact that an airplane will fly 3D at all is proof positive that it is no harder to fly then your average aileron trainer as long as it is correctly set up. As far as you wanting to make an airplane heavier, that is just plain rediculous except in the case of a sailplane where ballast is used for windy days for better penetration ( Higher potential energy equalls more kinetic energy ) but this is onlt because it dosent have an engine in front.
Oh Gawd...
You're dealing with a relative novice that has little experience, not an IMAC flyer.
His plane is over specs by a very small margin, he's never had to deal with 3D aerobatic planes, nor those that have inherent instabilities designed in for tumbling, snap, etc. purposes.
You CAN obtain very light Extras that loose many of the idiosyncracies of a normally loaded Extra, but that is beyond his scope. That is why he wants to STRENGTHEN things, as his landing skills are not up to it yet.
I've followed the OP through many such threads as he has progressed, answering his questions all along, and there have historically MANY MANY times such as this where he is focused on something too advanced for him to think about.
Your advice is like answering an overweight rider who asks about making his bike lighter to make things easier, by telling them about Carbon Fiber bike frames... it's a specious response in this case even though technically correct.... the bike rider needs to loose the weight not the bike.
Ameyan needs to fly more and stop fretting about a .2kg weight difference.
The context of these posts is important, something you've overlooked.
