Neville,
Glad you are keeping the Hurri's alive! I have been flying mine. Cg is 4.5 inches from the leading edge at the fus. I built the wing and stab as per Roy's plans as far as the Incidence numbers go. The Hurri flies very well this way. My Hurri does not like a lot of flaps. I personally like to "Drag" my airplanes home using a lot of flaps. Not so with the Hurri. I'm flaring at about 25% power or so With little flaps. If you want to talk Hurri's, just PM me.
Take Care.
Chuck
