Dale showed up at Day One of the Knights of the Round Circle 2022 Bob Palmer / Dale Kirn Memorial Stunt Contest at Whittier Narrows.  He flew his Monoline stunter for us again.  Mind blown…

Joe said that the plane shown had a custom (nylon?) barrel cam instead of the usual brass cam. I didn't ask him why.... This plane had a .19 engine and the lines were long.

He also flew a 1/2A with a Cox Black Widow and the "promotion" foam wing skins.

I remember Joe flying Dales Thunderbird at that VSC.  It was interesting watching hin on the controller.   D>K

It is kind of odd, but I think of it this way:

A standard setup takes two lines but only one hand, but a "Stanzel" setup only takes one-line but two hands....

Joe said that if he makes a lot of consecutive loops, he then holds the plane level and twirls the finger gizmo (nut) to get it centered again before the next maneuver.

I saw him doing some pretty good square loops with the little .19-powered job. I'd bet the T-Bird was a lot more impressive

There are monoline handles that need only one hand to operate (not like Stanzel twisted wire type).  I wonder if anyone has used one of these single hand handles on a stunt ship.  If so, it would seem that the handle would have to have some sort of strap or clamp to the pilot's forearm to operate satisfactorily to get through the pattern.

Flying Monoline is waaay diferent.  I tried it in high school.  It's difficult to balance the force of twisting the line with the resistance of the control surfaces(there's a spring inside the cam mount).
I did manage to get in several flights before breaking up an airplane.  I gave up.  It does work better for speedflying.  One line has less drag than two.

I've helped several kids and adults learn to fly. With a couple of trys they could all do level flight in just 2 or 3 flights.

The big problem there is that moving the hand an arm in sync with the plane because you can get the same movement with both hand movement and arm movement.
The problem comes from the controls responding to moving your arm relative to the plane and/or using just the wrist to move the controls, or both together.
Even with help I had trouble showing them how you can start a loop with just arm movement, sort of leading the plane.  BUT it was tougher to learn that you had to add some
arm movement to follow the plane while you were bending the wrist to move the elevator. ds Otherwise, the plane would neutralize the control as it caught up with the hand motion.

That's why, if one tries to teach someone it really helps to demonstrate with a dry run that it's easiest to learn that when the plane goes "over the top" of a loop the pilot has to use
both arm and hand to keep the elevator up to complete a loop.

Like ther sports, once you learn how to do the basic moves it's something that never goes away.

Keith,

Not sure what type of handle you are referring to...possibly one like the picture I saw in an old magazine? It had a curved rack where there is often an adjustment bar on a standard handle. There was a carriage that tracked along the curved rack with a pinion gear and likely a pair of bevel gears to change direction 90 degrees to point at the plane. The one I saw looked a bit fragile?
