atmospheric layers and tiny planes (especially micro radian)

if you dig into my 7 pages blog, you will see that i have been deep into tiny planes. from that, and my previous experience in free flight, i have learned that there are layers (even indoors in large hangers) that, like blankets, separate the air and sometimes behave different-and therefore drag the plane into that. especially the small 1s.
and with the micro radian, https://www.rcgroups.com/forums/show....php?t=2089760 that is indeed a sailplane, this is more noticeable. with it, you will see that for instance, it climbs at different angle depending at which height it is: typically at launch it climbs at 30 degrees at half throttle, then at 10 meters (33 ft) it increases its angle, and then at some 20 meters (66 ft) it increases it again. and when gliding down, the angle changes too, and when approaching the land it sinks even faster and becomes buoyant, like if floating in boiling water, to the point that even stalls. not only that, frequently the wind changes direction from layer to layer, even dramatically, like at 1 layer you see it blowing from the north and next blows from the southeast. this is more noticeable with fog, that sometimes is seen as a blanket covering a field-or at certain height-and little bit beyond suddenly disappears.
just keep this in mind and try to adjust-and enjoy the vagaries of the weather!
