Nice work! I think there are a lot of people that could benefit from something like this. It will be interesting to see how clean you can get a set up like this. It may even help pg pilots make the transition easier and I agree that the non head first idea sounds safer.
Thanks for sharing.

Is this video of THE hangglidingmichael or is their more of you out there?
If it is the one and the same, very talented flying.

I am usually trying to avoid it as it creeps into my flying technique, works against what I'm trying to achieve, and wears me out faster. Thanks to my GoPro, I know that I tend to cross-control in left turns more than in right turns.

Always learning...

A little cross control helps centering with both wings. For me I refer to it as High siding the bar in a hang glider.

Risking telling people what they already know, here is some explanation.

In aircraft with 3 axis control, cross controlling is ailerons and rudder in opposite directions, as in right aileron and left rudder at the same time. Used to keep the plane coordinated in slow turns, lose speed or altitude or in crosswind landings to line up both the flight path and the plane with the runway.

In hang gliders, cross controlling is moving your head one direction and feet the other, as in head right and feet left, without moving your center of gravity with respect to the control frame. Easy to do but not very effective in controlling the glider.

I think the 'bare' is a typo, caused by the 'B' being right next to the space bar, but I could not resist trying to include a little humor.

In a sailplane cross controlling is sometimes used to help stay in it and keep the yaw string straight which keeps us coordinated. The spin is then caused by a high AOA during cross controlling which we practice. We can use cross controlling to loose altitude on final if need be because we can control our speed in a slip with our elevator. True cross controlling in a hang glider for control doesn't work as demonstrated by many of my students.

Sailplanes, like most fixed wing aircraft, have three axis controls - rudder, elevator and ailerons, which control yaw, pitch and roll respectively. Hang gliders have control in two, pitch and roll, which results from your body's location longitudinally or laterally. I understand that in 3 axis control aircraft one can give a roll input and an opposite rudder input causing the aircraft to be banked left but yawed right for example in order to slip to lose altitude. How does one cross control a hang glider with only 2 axis control? I can see how a sudden, sharp twisting input can induce a momentary yaw input force but I can't see how that yaw input force can be sustained. Rotating your body cross to the relative wind creates more drag but how does it impart a yawing action? I will enjoy being educated on this as I have never understood how true cross controlling is possible in hang gliders.

>>bare thermalling

Either flying while wearing only your harness, helmet, and aftershave, or a typo. There's also 'bear thermalling', which is a spring-time phenomenon when the bears wake from hibernation and are extremely air-horny after a long grounded winter. Give them right of way, even if they are turning in the wrong direction in your thermal. It's also smart to give them your sandwich & beer in the landing area if they ask, considering they out-weigh you by a few hundred pounds and are sharp of tooth and claw. Which brings up the topic of 'beer thermalling', which is primarily a summer-time technique, also demanding right-of-way... Push out! /jd

at some sites, with much shorter and steeper "ramp", this can be really hard to do. Ascutney for example.

For sailplanes, cross controlling is how thermalling is done.

For hang gliders, cross controlling while thermalling is not good.

Anyway, in this hemisphere this is not the season for bare Thermalling.

Cross controlling may sometimes be necessary to keep the yaw string straight, but cross controlling is also a way to do an inadvertent spin.

Karl, Big Guy. What is "bare thermalling"? Is that a sail plane term?
(I guess I can use Google to figure that out, oh well)

My First Glider was a 225 Falcon. I remember that glider as being
a Climb Monster. I found my self as I CENTERED A cORE OF A
THERMAL, i WOULD PUSH OUT WHILE hIGH SIDING. WHAT
A RIDE! That Glider had Little in the way in it's ability to Glide very Flat.
I t also was "VERY SLOW". But what a: "CLIMB MONSTER!"

It seems to me like unless you're in the mellowest of thermals, there's lots of bouncing around and being knocked about. Some sloppy flying is inevitable. Cross-controlling does reduce your authority over the wing though, so you won't be able to center as well or maybe even stay in the lift. That's how it will cost you. Use more rudder! /jd

That's the video I was thinking about when I wrote about the no-wind launch. Imagine trying that in some high-performance competition glider with a polar much further to the right (i.e. faster stall, min sink, best glide, etc. air speeds). In the past I launched my T2C 144 and Covert harness from the same spot in the same conditions but took a half dozen or more extra running steps. These days, I'd just carry it down to the steep ramp rather than risk a downhill launch whack.

I have said this before and I'll say it again - If pilots want to improve their launch skills then they can easily practice on level ground and especially in the LZ right after they've landed (if there's no incoming traffic).
