The ailerons are fine and the roll rate is perfect for me. Doesn't seem to be any adverse yaw either.
If it's nose heavy would it want to stall in a 45 degree inverted climb when chopping the throttle? Wouldn't it require quite a bit of down elevator for inverted flight? Right now it requires almost none.
Now, I got 2 incidence readings last night and I'm wondering about my meter. The very first time I checked it, it showed 2 degrees negative on the main wing. Now, I wanted to keep checking to make sure things were correct. Subsequent readings were in the 1/2 range.
I will check it again tonight because I really don't think its the CG. My instructor from when I was training flew it as well and he thought the CG was fine.
The plane is certainly flyable as is - just not to my liking
Downthrust:
This was one of the fuselages with the firewall glued in backwards. I wonder if it the thrust line of the firewall is off. I drilled out the hole for the throttle pushrod myself (like others have said to do on here when this happens).
