Doesn't sound like you need to worry about engine life, either, unless your TBO
is Real Soon Now.

I've owned my Stemme now for 5 years and have logged around 850 hours (327
flights) on it.Â* I think I've used around 80 engine hours during that time which
is about 15 minutes per flight (start, taxi, takeoff, and cool down).Â* I tow the
glider from my hangar to the apron before rigging.

And yes, I fly with a different mind set than I did in my LAK-17a:Â* I must be
within range of a runway suitable to make a normal takeoff at all times.

cold engine develops more power.

The typical self-launcher puts maybe 5-10 hours a year on the engine. If it
only lasts 200 hours before a major overall, that's 20 to 40 years! The Stemme
is usual for a self-launcher because it's also a good airplane, and 200 hours
might be only two or three years.
