I absolutely love my 177 RG Cardinal. There is no other airplane I would rather have. The RG is quite a bit faster than the fixed gear models, and has a max gross of 2800. I have 978 lbs useful in mine,
and I can carry 60 gallons of fuel. She flies fast and efficient. Heres a photo of my panel in flight:

I'm at 4500, with power pulled back to 22 squared. She's trued out at about 145 MPH and burning 7 GPH and thats running very rich. You can see by the EGT, I haven't leaned it out in this photo. I wasn't 100% sure of that EGT gauge, and I was going pretty easy on leaning it since it was still farily new to me at the time.
Having said that, I get better than book numbers by a little bit. She has a powerflow and one of those fancy challenger air filters. I also run a three blade prop. I have been able to do 170 MPH true at about 10 to 10.5 GPH in this bird at about 24 squared.
This airplane fits my little families mission profiles perfectly. Having nearly 1000lbs useful load and the flexibility of 60 gallon tanks in a slippery and powerful airplane is something I never thought I'd find. My wife, daughter, and myself can all load up in the plane with plenty of bags for our trip and tanker fuel for safety and still not be at max gross, and we do it all COMFORTABLY. This is the only airplane I have ever felt comfortable, with plenty of elbow and shoulder room in. She doesn't even have the best paint job (its getting a bit rough), but I still get lots of compliments and comments just about every where I go. People seem to be drawn to them because you hardly ever see the Cardinal RG's anymore. And this thing looks soooo sexy in the air too
I might be a bit biased though....I do love this airplane:
