I loved the TB20. Especially after all the 20 yr old 50's designed Piper/Cessna stuff.
We had one at MB in 94 and although it was second-hand (D'Oh) it was great I thought, I loved the seating position and the different switches. It made anything that came before feel like a HD Holden. I admit it evoked a real love / hate relationship with some of our students / clients, but so did getting out of the VK and and into a Pug 504. It was a bit faster than most things with the same donk and the "hard -to-land" mis-nomer was because it had a higher wing-loading than most of the ancient **** we'd all be flying before. And I might add, if you ever got into an Aerostar of Metro II, is was good famil. for those types in that sense.
So yeah, not foolproof, but fun, I thought. TB20 anyway, never did the sisters.
