>Also, Im wondering if because they typically do this head down in a cell, is it the wings simply can't be deployed for flight. Is there some "disconnect" mechanism? Can they do this outside of the cell?
There's a lot of science about how bees use their indirect muscles to fly, heat, and signal and it's all fascinating. The muscles are referred to as stretch-activated or asynchronous. Meaning they can react to neurological signals differently than our muscles. One signal starts them moving and they work against each other (horizontal and vertical pairs ) in an antagonistic way that keeps them moving until another brain signal comes along. That explains why a bee's wings can move faster than would otherwise be possible if one signal created one movement. Bees typically pre-heat their flight muscles before flying in the same way they use them to heat during thermoregulation. Bee's can send a slightly different neurological pattern to their flight muscles when they want to use them to heat. The heater signals put the muscles in " tetanus" locking them in place but consuming energy and making heat without moving the thorax - the restraint of the cell is not a factor. They can switch them to flight mode with a slight change in the neurological patterns which releases the locked mode and allows the thorax to vibrate and the wings to move freely. At times, one can observe the pre-flight heating on the landing board before takeoff or when a forager is leaving a flower. Bee's use their indirect muscles for heat, flight and vibrational dances on the comb, all of which are active states and deliberately under the bee's control.
