RE: ParkZone Radian RTF
I fly mine at about 5mm back from the recommended. On another note I noticed the plane needed right trim so i weighed the wings on a gram scale and found the left one heaver then the right so I sunk a small piece of led on the cg mark in the right wing. Put the wing halves together checked the left right ballance. Flys great now. When the wind is up 10-15mph the guys in our club put a steel rod inside the wing joiner tube they purchaced from home depot for ballast. I have not tried it yet but they beat me out in a limited motor run contest when the wind went above 10 last Sat. that extra weight allowed penetration into the wind.
