The Fun Tigers are a little heavier than most profile ARFS, I have heard alot of stories of the horz fin folding up on them too. The covering on them is the sticky back kind and that probably adds to the weight. I didnt like the way the did the servo mounting in them either.....They sell an ARC version of this plane, haven't heard much about them....overall...now this is just my opinion.......comes in low on the "fun factor" scale.....G
