Based on how similar this plane is to the Twister, I would just leave it where it is, fly it and go from there. No point in putting a bunch of effort in to move the CG back when it doesn't need to be.

I just finished mine tonight: YS170, Hatori pipe and header, Hyde ARIA mount (this adds nose weight.)
Futaba 6014Rx, BLS451's on ailerons, BLS351 on rudder 3421SA's in stabs.
15x12x4 APC and True Turn spinner.
It is so nose heavy it isn't funny! I sure hope it needs to be at 185mm because it's going to take an effort just to get it there.
I have not weighed it yet. It sure feels light... but only the scale will tell. I was planning to use an 1100mah A123 battery unregulated.
I may be forced to change the spinner... but I'll see how far back I can get the battery. Also a 2 bladed prop may weigh less...
Quality is "okay" but not stellar. I am quite happy how it turned out however. Incidences etc seem to be a-okay.
