Default u-can-do 60 flight characteristics?

I'm novice flying a u-can-do 60 with FSii91 (2 degrees right thrust) and 15x4w APC prop (9500 rpm max). The plane balances inverted at 5 inches with no added weight. I use single rate with 20% expo on all surface controls with elevator +- 1 inch rudder +- 2 inches and Aileron +- 3/4 inch travel. No significant problems with over controlling the plane. I do find some of the flight characteristics outside of my expectations and would like to hear your experiences and get some advice.

1. The plane requires more than a little down elevator for level inverted flight.

2. I lose a lot of altitude turning with the ailerons. Previous planes Kadet Senior, Something Extra and 4* required only a little up elevator to hold altitude. The u-can-do seems to need a lot of up elevator to maintain altitude.

3. I end up with too much up elevator on final approach turn (needed to prevent losing altitude too fast). When I level the plane off I have to remind myself I'm holding a lot of up elevator.

4. The u-can-do is very sensitive to wind on landing. Sometimes it will float in and just slip to the side with wings level. Other times the tail shifts suddenly and or a wing will drop. Without wind it is a breeze to land with no bad habits. I usually keep 1/4 throttle until about 1-2 feet over the runway to maintain control authority.

5. No problems with trims for straight and level flight.

Pilot problem, setup problem or normal operation? Note: The pilot concedes the need for more experience.

Thanks,
