I got a couple more tanks through mine yesterday. The walls have improved with practice, timing is a little more critical on them than it was with the Funtana. Harriers are great, with or without spoilerons. They may be easier without the spoilerons. I programed in ailevators and that inproved the already good roll control in a harrier. The ailevators improve roll control in a hover also. That was another thing I didn't care for with the Funtana, very little aileron effectiveness in a harrier or hover. The Funtana was very squirrelly in high rates with max throws on the control surfaces, even a quick turn would cause the wing to quit flying. It was almost inpossible to loop in high rates and even in low rates if you pulled elevator quickly the wing would snap. In its defence it would alway start flying as soon as you let off the controls. The Harrier is just the oppisite. Even in high rates you have complete control, you can make loops as big or as tight as you want and it never snaps, flying around is like flying in low rates only quicker. No squirrelyness at all. But when you move the sticks to the extremes, the Harrier can be as wild or wilder than the Funtana. The Funtana is for sale as of yesterday. On the last flight yesterday, I flew until I had had enough fun, landed, handed the transmitter to my son and said, "you should have enough fuel for a while". Several minutes later he was in a harrer about 80 feet up and the engine surged. I said " did you do that" and he answered "yes". A couple seconds later the engine quit. He said" I didn't do that". He dropped the nose and got it flying, but no way could he make the runway. He landed as lightly as possible in the uncut hay about 100 feet away. When we walked out and picked it up there wasn't scratch on it. The covering is tougher than it looks. The Harrier is holding up well to the hammering of the .82 with the exception of the wheelpants. The axle is inlargeing the hole in the outside edge. A small 1/6 ply plate on the inside should fix that. All in all an exceptionally fun and versital airplane.
