ORIGINAL: Super08
I use a program mix now set to a spare switch to give me a safe high idle for flying and doing stunts without fear of it shutting down. With a flick of the switch it goes to my set low rpm for landing. I do get a little bit of change with my low idle, but not a great amount. I would guess it is from changes in engine temperature.
BTW very nice Sundancer
Some IMO use a switch to set the idle which in my opinion is practical for IMAC flight, but not necessary with a well adjusted engine. I have my idle at around 1600rpm and had 2 dead sticks in over 150 flights on the DL50 because I accidentally turned the ignition off.
