How Low of an Idle?
I realize that there are various factors that effect reliable idle speeds. Prop sizes etc. I'm curious in general how low of an idle in RPMs does a typical .60 size two stroke glow engine get?

Seriously you can have a low enough idle that you'll dead stick in flight as the prop unloads and loads. My rule of thumb is low enough not to roll. On grass I let my wheels pretty much free spin. On asphalt I set my wheels to drag some

Depends on the engine too. OS engines can get down around 2200 reliably, while the cheaper Chinese engines like Magnum generally won't. That may not be a matter of quality though, since Magnums have more compression than OS's do and therefore it's harder for the momentum to push the piston past the top reliably.

I have always flown from a grass field, so rolling has never been a problem. I set my idle for maximum reliability. I cannot recall the last time my engine stopped because the idle was to low. I do see a lot of people making dead stick landings, with plenty of fuel in the tank. A lot of people seem to believe a very low idle is a good thing. I'm not one of them.
