hi everyone i have just finished the sonerai but have yet to fly it, it is fitted with all standard radio gear and covered in solatex i had to ease the le a small bit to allow a 4oz kavan tank to fit without fouling the wing fitting, the only problem i have and would like some advice on is the c of g it measures 60mm on the plan but seems too far forward, using the 30% rule it should be 72mm which seems better, anyone know which it should be. thanks, John
