I set my Great Planes CG machine to 78mm and added some more weight. Went rummaging through the parts bins and found this little nose cap which, along with the washer, weighed up exactly the same as the weight I was going to add, plus its a little more forward. Looks good and solves a problem, win/win!!
Plane without the spinner but with today's added weight:

With the spinner instead of the added weight:


Now, I may add just a bit more to get the nose down slightly but so far it looks good. I have to swap out the rx for the new one with the gyro so the final CG will be after that.
Rex, you said you adjusted your throws, what are they now?
I think I might move the aileron control rod position down two holes, the second from the top seems a little severe, more likely for 3D ing the plane.

Grossman56,
My high rate is 18mm, middle rate is 15mm and my low rate is 9mm up/down. Take-off will be on low and I can switch up if need be. I haven't moved any control horn setting yet. Rudder is per manual and felt ok. Using rudder with aileron made the turns more stable and smoother. I have the lemon 6 ch rec and haven't used a gyro yet. Never have used a gyro so maybe don't know what I'm missing.
Best Regards, Rex

I have to set my gyro up this weekend, I'll post a breakdown of how I did it. If usually have the gain set to the knob so I can increase or decrease it while flying, usually starting at about 25 -30%.
What I really wish is that the cowl ring was removable and not molded with the fuse. A plastic nose ring with sections like the Corsair had to add weight if needed would have been a much better way to go.
Now, we could 3D print a cowl ring designed to do just that but the surgery to get it on the nose might be an Elbee job.

Grossman 56,
I was thinking the same thing about the cowl. I'm going to measure it and if it gets torn up, I can make a new one from balsa or ply. A 3d printed one would be great too. May get to fly again Saturday to see if re-balancing helps.
