The RealAir Citabria has been around for a while, but its flight model is certainly not dated.  It was way ahead of its time, and it is still one of the best flying sim planes available.  Anyone interested in taildraggers should try it. 

 

On the subject of ground handling, I built and flew large-scale (1/4 and 1/3 scale) radio-controlled taildraggers for over 30 years and did a lot of experimenting with the longitudinal positioning of the main landing gear.  It's a trade-off:  If the main gear is positioned far forward of the plane's center of gravity, then you have a decreased chance of prop strikes or nosing over, but the plane can have an extreme tendency to ground loop or to bounce back into the air (just like the German Me109). 

 

On the other hand, if the position of the main gear is moved rearward, then there is much less tendency to groundloop or bounce, at the expense of an increased risk of prop strikes and nosing over (like the Citabria and the Spitfire - the Spit needed a mechanic sitting on the tail to prevent nose-overs during engine runups!).

 

(Disclosure:  In real life I've landed a Piper Cub, but I must confess that I've never flown a Citabria, Spitfire or a Messerschmitt Bf-109). 

Taxiing a B17 with a crosswind is fun especially with that huge vertical stabiliser surface!!!

If an accu-feel and accu-sim user, try turning accu-feel on in the cub (off by default) and play with the settings such as the side forces slider. You can then tune the ground handling side forces, bumps and the rest of it to your realism/immersive needs.

 

Also for ground handling I believe its worth having the ground friction fix for fsx (availiable in FSUIPC I believe) that will also play a part
