I don't understand why TMGs aren't more popular.
'cos there REALLY awkward to get in and out of the average hangar. We had one for years until recently and it only came out on high days and holidays when there were enough people around to handle it. Also, they don't seem so good in the rough weather that our PA28 can handle. Oh, yes, and they only really come in to their own on decent soaring days.
I've seen the TMG hangars at Enstone and they seem a bit better, being purpose-built, not like our hangar.
Having said that, I was privileged to have a few goes in ours before it went, got 800' climb out of it with the engine off, up to the cloudbase, and I'm not a glider pilot, so I can see they're good fun.
