The 140 is a good airplane. It's easy to fly, long enough wheel base that it straightens easily.
The 0-200 is a good mod, as is the alternator STC and the gear extensions.
It flies the same as the 120, except you have flaps. You can slip it the same.
If you've been flying the 180, 185, etc, then you understand the propensity for the spring gear to...spring.
