I have heard the mention of needing lead in the nose to achieve CG... don't bother.

I put a 3 inch spacer in to ensure my battery does not go as far forward pushing the CG back even further.
Outboard of the nacelles, feel for the panel lines for the LE slats. I'm balanced on that panel line 3 inches out from the nacelle. (at least 2 inches back from what the instructions say)
I may push the CG back more...

I'm using 4S 4400 and 5000 mah 20/40 C Sky Lipo packs from Nitroplanes. (because I have a lot of them)
Appx 4 min per charge high performance... 7 min at 50% throttle (which gives decent performance)

Result: A smoother flying model that handles inverted much better. Looks like the horizontal incidence is set for a nose-heavy model as the elevator is visibly down for level flight.

The only bad thing about this is you can easily cause the plane to rotate and stall even with full down elevator if you apply power too fast. It lifts off fine at 50% throttle (stock fans and ESCs)

Don't add unnecessary lead for CG. If you are paranoid slowly move the CG back from where the instructions indicate. I moved the battery back 1 inch at a time using styrofoam block spacers.

It can easily handle more weight and I plan to Y in a second pack on the CG for more duration.

Just be a bit careful applying throttle at low speed.

I'd rate the plane 9/10 value.
RX-ready (which also doesn't have a battery) Estimated capable of 105 mph straight from the box.
