I have both of these planes and for a second plane I think I would go for the Tiger. It is a little more forgiving, a little slower, and lands closer to a trainer than the Sportster. That being said, I fly my sportster all the time and my Tiger collects dust in my shop. The Super Sportster is just a great, honest flying basic aerobatic plane. It can be a very fast plane with the right engine.

One other really good second airplane to think about is the Astro Hog. It is in my humble opinion THE BEST second airplane design there is PERIOD!
