I think most of us (myself included) would tend to pick the trainer that we learned on as our favorite. Mine was a Midwest Aerostar 40 built from a kit.

I still REALLY like that airplane and sometimes throw a radio back in it and fly the heck out of it. That thin will fly upsidedown as long as you want it to, does respectable rolls and stall turns (for a trainer).

I consider mine an "antique" since it was built about 15 years ago and most of the covering is still original!

Having said all that, the Kadet LT40 (or any of the Kadets for that matter) are also right up there with the best.
