Something no one is taking into consideration is your abilities, and/or luck. remember that your second plane just might be another trainer should your first one (God forbid) be destroyed. Also, the while the planes mentioned are good second planes for some, they are not good for all.

A "typical" second plane has these two features: A semi-symmetrical airfoil, and a shoulder or mid mounted wing.

You might be ready for a low wing plane right after your trainer, but don't put the horse before the cart.

A VERY good one to consider is the Great Planes Easy Sport.

A stik can be good, but look for one with a semi-symmetrical wing.

And don't be too anxious to lose the rubber bands. Remember, in your second plane, you're learning new things. Every learning process has it's bumps, and those rubber bands will ease some of them.
