By the way,
What s the best way to feed a servo wire through wing ribs. This was an ARF and didn't have a servo tube. I tied the servo wire to a fishing line and pulled it through to the aileron hatch. But, The J-connector kept catching in the ribs. What could I do to make the job easier and safer for the plane?
Here is what I have done over the years and works well.
Instead of string or fishing line I use a fairly stiff but bendable wire such as commonly called stove pipe wire. This wire is stiff enough that you can guide it in and pre bending as you feed from the wing root access hole(s) to the servo bay.
The problem in pulling the plug back through from the servo bay is attaching the string or fish line to the plug by tieing. No matter what you do it will bend sideways at every rib you bump into.
The solution is using the the stiffer wire, not string lineing up the end of the protruding wire straight alongside the plug then attaching only with shrink wrap. This will keep the plug perfectly aligned for the smallest holes as you pull then simply cut the shrink wrap away after pulling.
Every airplane does not of course need this of course. Some will almost fall through but for the occassional persnickety one this usually gets the job done easily.
