I've been flying a CB-1 w/O320 for twenty years but have never flown a Classic. I'm sure there are forum members here that can help you with Classic flight characteristics. My Hatz is pretty much built to plans with no modifications except for dual tailwires which I added a few years ago. Its has no electric which keeps the weight down (917 empty). These airplanes are weight sensitive. You can really feel added weight in the way it flies. That being said, I have had 300 lb passengers with no problems. I don't think that you can physically over load the airplane or get it out of CG range.
I have a wooden prop that my Dad carved which limits rpm compared to a metal prop. But I still get 100 mph cruise at 2250.
Takeoffs are in the 300 ft range with around 1000 fpm climb at 60 mph. Landings can be 300 to 400 ft with good brakes. Wheel landings are easy because of the firmly sprung gear. Full stall three pointers will roll the tailwheel first. I believe the Classic may have extended gear to cure that.
Control pressures are light compared to factory builts, but not as light as a Pitts. Roll rate is faster than a Citabria. 1 G aileron rolls and point rolls are very easy to do with an entry speed of 110 to 120. Loops are very tight with an entry speed of 130. Stalls around 40 to 45 are straightfoward. Spins rotate fairly quick with instant recovery. The first time I spun mine, I didn't get the nose up enough. When it broke it spun flat for about half a turn then buffeted and spun normally. With a good break it spins nicely.
I have had many pilots solo the Hatz, from my teenage son to very high time pilots. All have had high praise for its handling.
While it is not a "hot" ship, it is a taildragger and does require attention until it's tied down. If all you have flown is a Cub, it will feel a little more demanding but not much. It feels more like a clip wing Cub to me. Most of my pre-Hatz flying was in a Fly Baby, and I had no difficulty transitioning at all. After I had flown the Hatz for three years, I was offered a Pitts S1 to fly and had no problem. I think this shows what a great airplane the Hatz is. Its a great all round airplane. Decent cruise and light acro capability. Of course the Classic will be a little faster and roomier.
I hope this helps.
