You might be better off with a an RV-9...I believe the 9 has an even more eficient
wing for cross country work...Really only want a 7 if you intend to do aerobatics.
You can still put a 180hp motor in it but put a Catto fixed pitch prop on it to
limit it to 160hp.

My 7 sucks in turbulence....any airplane that is this light (empty weight 1103LBS,1550
loaded by myself, full fuel and a bag) will get bounced around more than
a 3K lb Bonanza. I use to fly my 7 from LA to Salt Lake city. I have over 85
round trips to be exact and with my autopilot, sat weather, sat radio and tcas
it is an awesome machine. My 7 would do the trip 563NM in 3.5 hours average
and burn 26 gallons of fuel with a 180HP with fixed pitch. Not to shabby.

I'm getting ready to order a RV-7 within the next few days. In reading the many
posts comparing a RV-9 to an RV-7, I think I'm comfortable going with the 7.
Before ordering, I'm wondering if anyone on the list flew a Bonanza or Baron prior
to moving to the RV-7 since I have over 1,000 hours in these aircraft?
Essentially I'm trying to get an idea of what I've read on the list referring to
the RV-7 having lighter control forces than the RV-9. How would you compare
the RV-7 to a Bonanza? Lastly, my basic mission is flying around the area, hence
the RV-7, but I do about 1 cross country a month.
With an autopilot, are the lighter control forces a non-issue in cross country?
How is the RV-7 in turbulence compared to a Bonanza?
Thanks!

Question.......what does the Catto prop have to do with reducing the HP of
the engine?

Depends where the prop is pitched...If you pitch a FP (or ground adjustable) prop
to make say 2400RPM it the engine will be making a lower power...I read somewhere
that a O360 Lycoming at 2400 makes 160HP...need to check the power graphs.
If your FP prop is allowed to go to 2700RPM there is your 180HP but then to reduce
power in cruise you will have to partly close the throttle...This is an inefficient
way to run the motor due to increased pumping losses...I.e max mpg will
be got with the throttle wide open.
That's partly why C/S props are popular because you can increase pitch and keep
the throttle wide open.
