RE: Boomerang XL CG

I found the recommended CG very/too conservative. So much so, that I stalled on landing damaging the front U/c (JetA1) at quite a low angle of attack.
Talked to Ali about it and he said that CG is far from critical and to start reducing the ballast out the front until I felt comfortable. This happy state occurred when I had taken 500grms out the nose and battery area.
I would suggest you fly cautiously at first and keep the landing speed up until you are confident that she will hold your normal landing AOA without a stall. I took out 200grms a time. After that she flatters your flying something rotten!
My other caution is to check the piece of ply holding the canopy at the back. Mine did a premature release in flight. To be really safe - I would cut away the existing epoxy and replace with Hysol.
