S/N #3 has over 600 contest cross country miles, has had a midair, been attacked by a dog on a ROG launch resulting in a broken tailboom. You think about moving on to the next one but has treated me so well I have to give back.
The stab pivot point is a carbon rod joiner going through a brass tube in the fuselage. There was always slop in the area as the carbon rod diameter is .248" and the is at least.250". I machined a bushing from 1/2" aluminum stock reaming the ID to .2485.
New fin post and refitted stab made it look new again.

Made a new finpost replacing the JR 9411 with a Futaba BLS153. Lighter and just as strong.
Reversed servo with output drive closer to drive pin making for smaller linkage.
No play at all in the horizontal. Shortened the stabs 1/2" each side. This removed the microballon root filler saving weight.
New root rib 1/8" balsa.
