How come all the gilders that I see now seem to have lawn mower engines that pop up from behind the pilot?
Because the ones higher up haven't needed to deploy engines yet
Makes a nice alternative to ending your day landing in a field and if your home club has unsoarable conditions you can always motor to a good area then back home for tea. You don't need a licence for them provded they are not powerful enough to launch the glider (if they are then they become a SLMG). Obviously they are much more expensive but for some it's worth the compromise.
The rest of us however get to visit the farmers and do the "where am I, who has a key to the gate, and can I get a car+trailer here" fun.
