akschu:
What you describe seems to be caused by 2 things:
1) Flat bottom airfoil
2) Rearward CG
There's not much you can do to get rid of the 1st unless you change your wings or airplane, about the CG you can have it a little nose heavy, it should land faster and stop "ballooning" so much.
If you want fast, side slide landings I recommend a World Models T-34 Mentor, I have it a little heavy and it lands hot!
I'll see if i can upload a video somewhere so you can see how it performs, maybe you'll like it

and for it's price you can't go wrong!
Cheers
