We're taking our first long trip in our k and I love the plane too. We'll put 2500+ miles on this week and have fun doing it, the 182 I used to have would be torture! I've flown everywhere from flight levels ifr to vfr at 10.5 this trip with solid performance everywhere.
The wife HATES flying, and she's even mentioned how solid the mooney feels. I think she's almost starting to enjoy it.
For me, I had to force myself to go fly the 182, don't have that problem with the K, I'm always looking for an excuse to go somewhere, to the detriment of my bank account.
Coming west this week we trued at about 190 at FL180, down low I was showing 170k ground at 10,5 VFR and I can't remember the true, about 175-180 I believe.
I run conservative (I think anyway) on my leaning and was running about 1500TIT and 14gph on the flow meter for both. Can't complain about the economy. If I trail flaps I can keep the cht's in the low 300's and not see a noticable speed difference. #3 on my airplane will creep up a little, need to see if it's the probe or just airflow.
Did I mention how much I love this plane? She's currently on the ramp with every cover known to man on her. Pitot, nose cozy, cabin cover, double tie downs
