DKY,
I have owned 2 of these back in the day,1 std version an 1 comp version. The comp version was a little lighter by 1.5lbs as the cores were cut out and lightend,really did not notice that much difference in flight.The planes did fly very true and predictable.Getting the CG right was a lil issues but came around on both of mine.(WARNING)-very fragile in the landing gear mounting area,one mishap and glass work for sure.Check and reinforce in that area.They came out at about 43lbs on the comp and about 44.5lbs on the std version.All in all a good solid performer,lil heavy for my taste,but solid.(THIS IS JUST MY OPINION AND WHAT I FOUND)
Good Luck!
Dave
