The HpH ones run as long as you have fuel left - maybe 30-40 mins at a reasonable power setting. Time to overhaul is 50 hours, which at the rate I use mine is going to be somewhere between 10 and 20 years. Cost is said to be a few hundred euros - it's basically looking at the bearings.

I believe the overhaul time is 25 hours, at least for the HpH gliders.
