Well, if I'd of been paying attention, I could have rotated them and easily gotten
another 70 from them probably. But, I just got the new Goodyear Flight Custom
III's installed last night and then went out and shot some landings. WHAT
A DIFFERENCE! The GY's are 10 times the quality of the stock one's. The sidewalls
are definately far more rigid and the tread is thicker. The rubber seems
a lot "harder" too.
I noticed that the old ones had a "flat spot" when I was removing them. I just
thought "rough" was the way the RV's were suppose to ride. Now the plane really
rolls smoothly. It also seems to track down the runway much better. Wheel
landings are a thing of beauty, and I've almost got that three-point licked.
I was happy to note that my brakes barely look used! Since the brake incident
and subsequent replacement of the wheels and brakes, I have been ever vigilant
about staying off the brakes. I try to taxi like I don't have brakes. Guess
its paying off!
Yeah, I've been flying a LOT! I just can't seem to not head out to the hanger
after work and fly around. My Chevron av-gas bill was $2700 last month! I just
can't believe how nice the RV-8 is to fly. What a joy.
For those that are still slaving away, *keep at it*! It is worth all of the time
you invest in it...
Best,

put 70 hours on it already? You have been doing some serious flying! I've
got 84 on my originals and I've still got another 20-30 hours left in them. But,
they are not high quality tires.
>I'm ready to order new tires and tubes so I've talked to a number of other RV
owners asking their advice. I've always liked Michelin, but the RV guys near
me all recommend using the Goodyear Flight Custom III. They tell me the sidewalls
are much stiffer and thread is deeper and overall the tire is longer lasting.
Also, many local guys recommended the Michelin Airstop tubes. They tell
me they have no air leaks with the Airstop tubes. With my original tubes, I
have to air up the tires every 6 weeks. The Goodyears have kevlar in the sidewalls
which apparently stiffens the sidewall.

I might have been a little rough on Princeton initially, but considering how annoyed
I was at that prospect of having to replace them, I think I held back pretty
well: :-)

Just having to remove them to adjust the probe tip so that it wasn't touching the
bottom of the tank was a major ordeal. Since in a QB you can see into the
tank when installing them, they should be pre-bent to make sure they don't touch
or have an insulative piece of plastic on the tip.
And why the first three calibrations didn't take is completely baffling. I almost
didn't try to calibrate again for the forth time, but I was just so demoralized
at having to remove them and try to fit floats in, that I just gave the
calibration one more try. Whew, glad I did.
Anyway, I wanted to clear the air and that's why I posted my extended pirep on
the successful calibration finally. I sent the same report to Princeton, GRT,
and the GRT-EFIS forum as well.
I've got about 20 hours on them now since the successful calibration. They remain
about as accurate as I reported. They still give kind of wonky readings when
the tanks are full sometimes. The lower the fuel level, the more accurate
they seem to be. That being said, based on comparisons with the FuelChec DX
flow meter, I wouldn't trust the level probes more than about +- 1.5 gallons or
so (within 3 gallons of actual). But, that's good enough I suppose. I still
rely on the flow meter's fuel "remanding" mostly as it has proved to be reliable
to within .5 gallons or better.
BTW, the FuelChec DX has a really cool feature called the "Switch Tanks" warning.
You set it to the amount of fuel burn you want to keep your tank levels balanced.
For example, I have mine sent to 3 gallons. Every three gallons of fuel
burn, the FuelChec flashes a warning indicating its time to switch tanks.
I've found this really keeps the fuel balanced across the tanks. Its also an
excellent reminder every 20 minutes or so to check the fuel levels.
