DW Crash,

The 25 lb. spit is not a problem. It is the Super Tiger 3000 that is. I admit a heavy bias on this issue that has been formed from years of viewing Super Tiger flameouts wreck airplanes. That engine is junk and I have never seen one run reliably. Junk.

Now for comparison my spit is a heavily detailed scale machine at 27.5 lbs. I am confident that one could be built below 25 lbs. using the balsa tail lightening changes. I don't believe any of the postings saying that somebody has a Y/A Spitfire at 21 or 22 lbs. They either have a bum scale or they have not put adequate lead in the nose to get it to fly well. Something is wrong with that low weight. You have to put the lead up front to get a good flying plane. Running short on lead will give you a plane that constantly hunts up and down in a pitching motion. No fun to fly at all. I've tried it.

At 27.5 lbs. with a DA-50 up front my airplane is like driving a little sportscar around the sky. It will loop from level flight. It has a somewhat heavy wing loading that you have to respect more due to the high speed stall, but the slow speed stall is not a problem at all. Iknow that my clipped wing tips, which drops me to an 80" wingspan overall, is my main contributor to the high speed stall. You cannot pull it in too hard on the back side of a loop or in a turn at full throttle. It will quit flying and scare you to death as it plummets to the earth. Happened to me twice and I am lucky to still have the airplane. My situation is unique because I cut the wing. I don't know of anybody with a full wing version of the Y/A Spit that has ever experienced this. (Picture below shows the wing profile in a hard bank) Leo
