Wood removal

Greenie for Levent for showcasing a potato peeler. I need to steal the kitchen one and replace it now. I never thought to sharpen one, let alone use it as a balsa tool! Something else to keep in mind...if the cutting edge of the blade is at an angle to the travel of the blade, then it cuts easier. In other words, hold the tool at an angle to the stroke. Consider this is how the guillotine was improved...the chop became more of a slice.

Please excuse the cartoon image. I hope it shows well enough that the travel of the pushrod needs to be tangent to the arc described by the control horn. Typically the pushrod travel is parallel to the tail surfaces. In fact, the pushrod travel doesn't need to be parallel to the control surfaces, just as long as the travel is tangental to the control horn arc. Taken to the extreme, the pushrod could be at a right angle to the elevator, and as long as the pushrod action is centered on the tangent, the elevator swing remains the same.

If I have described it well enough, then consider that the un-even swing, or arc of travel of the control horn end can be manipulated to create an imbalance of travel such that the elevator can actually move more in one direction than the other. I have used that in the past to give more "up" than "down" such that pulling up creates an agressive up, and pulling down is less aggressive. This is good for getting away from  the dirt (or concrete), making tighter inside loops than outside loops, but then creating a softness when pulling out of the bottom of loops, or the apogee of a climb and dive.

Great job, OhBee,
That sure is cute looking. Any chance you traced parts so it can be replicated? I look forward to seeing the completed model.
