Hi,
I am looking for a way to slightly improve the inverted flight performance of my Cermark Javelin II. Inverted flight needs a bit to much down elevator for my liking. I have played around with the C.G and after putting a little more back the inverted flight improved a bit. Putting the CG even more back will make the plane to critical for me.
I also gave the engine a bit more right thrust and down thrust by adding one spacer behind the engine mount (haven't test flow it yet)

I was thinking about the ailerons now and hope you can help me out with some insight on the following:
How does the trim of the ailerons (both a bit up or both a bit down) effect the plane?
And more specifically, would giving both ailerons a slight bit of 'up' trimming positively influence its inverted flight?

Thanks,
Jock
