I’ve had several requests for the settings that I’m using for my Chocofly JS3, so I’ve measured them and set them out below.
Note that all these settings are very much a matter of taste/preference and reflect how you fly. I like to have my center of gravity as much as possible to the rear and love it when the glider comes down straight as an arrow with a bit of negative camber. I also only fly with minimal throw on the wing control surfaces when I can, but have larger throws available over a switch. On top of that I always define a “speed” (negative camber) as well as three “Thermal” (camber) settings (“small”, “medium” and “large”), where “large” tends to be a lot, but reduced towards the outer control surfaces of the wing.
My settings reflect the fact that I mostly fly my gliders in light thermals and on the slope. Others will have different settings and preferences. Also important to note that I’m still not 100% satisfied with these settings and, as with all my gliders, will continue to fine-tune them – the only way to get these right for you is to fly and adjust (not copy values from some vague internet blog ;-).
