Ron,

I reduced it to 6º (per plans is 12º), I maidened it last Sunday, and it flyes perfect, predictable, have no fear to reduce it...
I don´t have much experience and have not flown any other Hog, but this is a plane that doesn´t produce any stress ehwn flying...
What engine do you want to use?? I use a Ys63, more than enough, not unlimited vertical but loops can be veeeery large..
I hope this helps..
