Re: Light-Sport Aircraft Yahoo group Can cruising the Rotax 912 a bit below 5000 RPM actually INCREASE we

I have been using Ethanol fuels (10%) in our 912's here in the phoenix metro area for about fifteen years or more with zero problems.  Also zero problems with water in the fuel.  The Rotax engine is design to run around 5300 rpms all day, every day and could care less.  Rotax 912 engines obtain volumetric efficiency at high rpms and were designed so.  Lugging the engine at low rpms is not the best trying to save it? Those flying 50 to 100 hrs a year may die before the engine does. Keep the r's up in continuous cruise and watch the temps, high oil temp is the enemy.

And you'll save several dollars per hour in fuel costs! :)
