The 4*40 is a good choice for a second plane. Able to be trimmed as a primary trainer (can be your FIRST plane!) and able to be adjusted for Fun-Fly or Pattern aerobatics.

Its not the best at any of those... but there's few planes capable of being competitive in Fun-fly, move the CG and change the controls a little... and its competitove for Sortsman (maybe intermediate..) Pattern. Then change the CG and its a trainer again. All with a sport plane built EXACTLY by kit instructions and powered with a mild .40.
