I think you are measuring the C.G. from the wrong place...

If I recall it is from the LEADING edge ( I never seen it cited from the trailing edge but I could be wrong... ).

You have an almost identical setup as mine, and I find the C.G. to be very good, though as suggested do dial in a lot of Expo ( 50% ) on the elevator for both low and high rates.

Also make sure that the motor is angled up more than the default or the plane will pull the nose down when you advance the throttle.

I have no washers on the top standoffs and four washers on the bottom standoffs. This is about right.

Re: Weight

No that sounds right.

Take the battery pack out of the plane and hold the plane... it will seem very light for it's size.

The battery adds close to 14oz or so, so you're plane is right where it belongs...

The wing loading is VERY good, and it tends to float in for landings... the hard part is getting it to come down!


Re: Prop

Remember that your 13x8e prop will draw more power than the 12x8e prop I'm using.

With that motor ( I'm running the same thing ) I'm quite happy with a 12x8e prop.

Pick up a 12x8e prop and try flying with that... You can always switch up later if you find you want more thrust ( which I doubt! ).

The 12x8e also keeps the motor cooler... though I always wait 5 minutes between flights to let it cool down.

Nice setup you have there if I do say so... heh...
