Pitts Special from 2" foam...Photos

This is my latest creation from 2" foam, cut using a hot wire. It's a semi-scale Pitts Special, created from plans and photos I could scavenge from the web.

Wingspan: 28"
Motor: IPS twin B
Prop: 10-8
Battery: ETec 700 3S1P
AUW: 8.5 oz
Weight without batteries: 6.8 oz
Airfoil: Eppler 472 (fully symetrical)

I flew it for the first time today in high winds. It handled the wind quite well. On the first few flights, I didn't like the way it handled in loops, but I later discovered that I had the CG way too far back. After moving my batteries forward, it handled quite well. Inside loop and outside loops are easy. I rolls nicely, but I wish I had made the ailerons a little larger so that it rolled more quickly. One thing that is a little odd is that if I give it a lot of rudder, it turns, but it also wants to dive at the same time (anyone have any ideas?).

I can't wait to try it without the wind!

Here are some photos:
