Mr.PatternFlyer
Your opinion appreciates being majority. Someone thinks that Y-rod is difficult. That first reason is because the inside of fuselage of ARF can be hard to see.
Well, I will teach the way that linkage of Y-rod is easy for the people of being difficult.
First, the hole of 3mm diameter that it passes through Y-rod is made on both sides of fuselage near the tail.
Make a hole in accordance with the direction which Y-rod is passed through, the position.

Pass through the long plastic pipe of 3mm diameter from the outside of that hole toward the center box of fuselage.
Pass it through the other hole as well in this method.
Put 2 piano lines of Y-rod in the pipes each which passed to the inside about 1 inch each.
Pull it outside the fuselage with a balance doing two plastic pipes.
Then, Y-rod is supposed to be pulled in these.
If it is devised more, the hole whose it is thin will be able to pass, too.
