Flying Monoline gave you about as much control feel as using the Aramid lines for a two-line system, or flying yur 1/2A Cox RTF with the supplied thread lines.

Very mushy.

Dale Kirn was one of the few who could make Monoline look good on a stunt plane,

One of Stanzel's seling points was retaining control when the plane came in on the lines. My opinion? If you lose tension on the lines you have other things to worry about.

There were some real advantages, for example if the plane pitched up the line would be twisted into some "Down" elevator input, so long as you held the slider in the same position. This is also why you see the pilot hitting the slider with the palm of his hand now and then - when you do an inside loop, for example, the line has to take that same full turn to stay in the control center position. And you have moved the neutral position of the slider about three inches closer to the handle, so you have to twist it back to the center of the spiral.

Unlike a two-line system where you just swing yur handle and keep the same control setting throught the maneuver, with the Monoline you have to keep moving the slider as the airplane goes through its maneuver, or the control goes back to neutral as the plane turns.

All this makes Monoline ideal for c/l speed. You don't want any pitch instability, Monoline adds a bit of stability all by itself. With two lines on a speed job any twitch of your hand will deflect the elevator increasing air drag, and lowering your speed. Doesn't even have to be enough to see, it's there.

A properly trimmed speed plane will "Groove," and maintain its five to eight foot altitude with no control input. Once you are "Grooving" you can take your hand off the slider and make no more control inputs all the way to the airplane landing.

But sport and stunt? No Monoline for me, thanks anyway.
