Nice job. Are those really "jets"? I mean do they actually have mineature gas turbine "jet" engines in them somewhere? Just curious.

Yes all planes at this show use small gas turbines. Normally powered with kerosene. Some can also use diesel.

The power output is from 15 Newtons (1,5 kilos) on the smallest turbines, and all the way up to around 400 Newtons.
The turbines rotate at over 100.000 rpm's, so this is high precision machines!
The picture of the sailplane shows the turbine on top.
BTW, this sailplane is 7 meters in wingspan!
