Until some years ago, our club used to teach the first few lessons with
new students on TMGs (first a Falke, later a Grob 109). Finally we came
to the conlusion that this training was virtually useless for glider
pilot students because those TMGs handle so differently from "real"
gliders. Consequently we stopped all primary training on TMGs. We still
use them for simulated outlanding training with advanced students.

"True" self launching motorgliders are a different story. For a club
with no permanent tow pilot, a self launching two seater like a DG500M,
DG1000M or ASK21M may add flexibility to the scheduling of lessons.
