For most of that trip were you over landable terrain?The River Ranch to Wauchula run is about 1 hr. I think it was 49 miles.
I was in fuel conservation mode and averaged about 5600 rpm.
The course was really easy - I got on Art's tail and wouldn't let him shake me off!
Slightly south of due west according to my dollar store compass.
We may have cut-the-corner of the restricted airspace ever so slightly.
It was REALLY close for me on the way back to RR - I put 5.9 gallons in a 7 gallon tank with 5-7 headwinds.
I won't do this again with less than 10 gals aboard.
Look into Spot at www.findmestpot.com .I certainly wouldn't have wanted to put it down.
Not terribly friendly terrain.
I am, much like you seem to be, pretty conservative in my flying.
I am reluctant to cross water or broad forested areas.
So I try to pick 'oases' where I might be able to put down and move between them.
When I could see a bad stretch coming up, I'd add a couple hundred feet of altitude to increase my margin.
That said, I wasn't overly concerned about the terrain.
Fuel, yes. Cloud cover, yes. Head winds, yes.
I enjoyed it and would encourage you to give it a try once you've built confidence in your new motor.
A couple of things I'd do differently next time.
Fuel capacity obviously.
A better briefing on what we would do as a group if someone had a forced landing. Depending on pilot health, what exactly would we do?
A second bird with GPS capability. It occurred to me on the flight back that if Art (midget) had to set down, I'd be in a world of hurt - both pinpointing his location and finding the closest airport or safe spot to land.
