These are the easiest cheapest way to make control horns that I have found or seen anywhere. I was looking at a scratchbuild video on YouTube and saw what looked like a floss pick being used for a control horn. What a great idea. I went to the local Dollar Tree to get some foam board and what did I find? A 60 pack of these Aim brand "precision" floss picks for $1.00!
As you can see from the pictures, all you have to do is make three cuts with some scissors or wire cutters and viola! Best thing about these is the control rod holes are already there! Just cut to length depending on how much throw you want or leave the holes to make it adjustable.
I cut the bottom part at an angle to make it easier to poke into the foam when fitting. A little hot glue to fasten it down and you're good to go. Clean teeth AND cheap easy building materials. Can life get any better? Happy building everybody!
