Hi All,

I am new to LOP operations and am looking for some help.  I spoke with some IV-P owners in oshkosh about this and just wanted to get some more info and clarification.

I understand that i should run ROP until altitude, then i can run LOP. The CHTs are supposed to be 390 or less and the TIT 1650 or less. So since i have not made the "big pull" before, i would like to know how exactly is the best way.  Do i set the cruise power, say 30" and 2500rpm, then slowly turn out the mixture... Watch the temps rise ( how hot does it get before it starts to go down again?) and then keep leaning until i get the TIT back to 1650 and CHT to 380ish or below?  How fast should the leaning happen? I understand i dont want to get the chts and tits really hot, so i presume i should be leaning relatively quickly (half a mixture turn per second?)

Has someone ever made a little video with their point and shoot camera of this process while up in the air?  This would be handy for someone new to running LOP.

Thanks all,

Dico
