Thank you, Tim and Jock. An interesting reading.
BTW, the AGL height limit of 2000 feet for self-launching motor gliders seems to be a disadvantage as they will lose height while cooling the engine down and storing it away:
7.3.2.a Maximum altitude of climb after self-launch Motor gliders, after self-launching, must stop their MoP not higher than 2000 feet AGL, in the release area of the appropriate class.
