Ive always recommended the Sig Midstar as 2nd plane.
It has everything a good 2nd plane should have.

1. Its a kit.

2. Its rugged enough to take the abuse its likely to get.

3. Its aerobatic enough to hold your interest for a long time.

4. It flies great.

5. It is very good for landing practice. And landing is the
most important skill for you to master.

This is a plane you will learn to FLY. Most trainers only
teach you not to crash.
