I didn't like the heavy duty looking linkage for the ailerons and flaps, so I used a standard 4-40 clevis set up. One side is adjustable and the other is soldered on. I also did not like the giant metal control horns, so I made some from PC board. You will look a long time for the hardwood blocks that are supposed to be in the ailerons to mount the control horn to, they do not exist, in fact there is nothing inside the ailerons. I cut a hole for a block of balsa and used epoxy to secure it and the control horn, I'm very happy with the installation, much cleaner and sleeker looking. I'm going to have the paint matched for touch up purposes later.
The stock control rod on the right is pretty beefy looking, more like turbine jet stuff.
PC board horn with balsa block, you can see the aileron is hollow, all of these will need a mod in this area
for any kind of control set up.
Finished installation, nice a clean.
