Did it -- bought the Cheetah

Alas...

I am now the proud owner of a 1978 Cheetah with 868 hours total time.
AA5A-0660. Starting the annual tomorrow. Maybe new cam & lifters. A
little XC & TLC this fall & winter, then next summer -- gone.

Jay -- save me a room (the Connie), and a beer. Maybe two.

Too cool.

Alas? If I could afford my own plane, I'd be a happy camper.

Anyone with a middle class income (even low middle class) can afford an
airplane. The key issue is what other things are you willing to give up?
Are you willing to drive an older car? Live in a smaller home in a
not-quite-as desirable neighborhood? Eat in (as opposed to going out to a
restaurant) a few more times a month? Set the A/C on 80F instead of 72?

That's what it takes. We all make sacrifices to some extent in the pursuit
of our interests.

Duane, if you're that far into the engine, seriously -- do the
160 hp mod. You will never regret it.

That's the second time I've seen a reference to the 160 hp mod. I
thought that Cheetahs came with 160 hp from the factory. Every one
I've seen was 160 hp (thought it was part of the LoPresti magic speed
upgrade). I recall that the Traveller was 150 hp. What year did
they change the Cheetah to 160 hp from the factory?

Just Curious,

John Galban=====N4BQ (PA28-180)

John,

All Cheetahs were 150 hp aircraft, competing directly with the 150 hp
172 and Cherokee 140/Warrior. 80/87 octane O-320 Lycoming engine.

160 hp is a mod.

All the best,
Rick

Negative.

Negative. It's an STC. A very common STC, just like the
Sensenitch prop on the '75-79 Tiger.

Never did, AFAIK. See:

I sure liked the time I spent in the Cheetah, so I'm sitting here
being a little envious of you. It was comfortable for long trips,
about as fast as an Archer/Cardinal on 30 fewer horses and the
visibility was outstanding. Only downsides that stick in my mind are
that despite juggling umbrellas, the inside gets wet when you have to
deal with rain as you get in or out, and it doesn't carry ice well.

The ice thing is for-real. The wing will lose noticable airspeed
just in heavy rain. (Although, I think perhaps pilots over-estimate
the amount of ice other airframes will carry, and the proper conclusion
isn't "take another plane" it's "don't go" if the "ice risk" is there.
Unless the other plane is known-icing certified. Just my opinion.)

If the inside got significantly more wet than a Piper, you didn't
have a big enough umbrella. You can tell a Grumman pilot by the
size of her umbrella *g*. We have 3 that size. I do experience
"Cessna envy" when it's pouring rain and I have to load the plane
on the ramp, but only then. When I flew Tigger home, my checkout
CFI referred to me as "Cessna-handed". It wasn't a compliment *g*.

Cheers,
Sydney

I am wary of the condition of the cam. The airplane has been flown ~50
hours this year past, mostly me before I bought it, but in the 5 years prior
it flew less than 50 hours total. There is more than a little potential for
rust and pitting. Then again -- it may be perfect as the owner declared.
(I insisted in pulling two cylinders. He refused, but reduced the price by
half the cost of the cam. I accepted that. There is a much longer story.)

With this annual, presently underway, I will have two different labs do the
oil analysis plus "ferrography", to see if they can detect any rust or
pitting of the cam shaft & lifters. If their analysis is good, and the
compression holds, I will not pull two cylinders to inspect, and "fly it
till I fry it", waiting for metal to appear. When that happens, then out
she comes, and yes -- a zero time engine and the 160 STC.

If the engine holds together, I will likely paint the old sweetie soon. I
am aware that painting Grummans is another subject entirely.

Thanks for your help. I'm off to the airport to tear the old sweetie apart.

Congratulations, good luck, and don't forget to join AYA if
you haven't. Next July in Wisconsin Dells

Yes -- Gino Dimenna our local AYA guy is on my case too. You will see me on
the list soon. I thought the next convention might be in Qualicum here in
British Columbia?

See ya !

Cheer,

Yes, I'm in Vancouver (150 NM north of Seattle), so we know a thing or two
about rain. Oh yes. We all have umbrellas in our car, in the front foyer,
at the office -- and in the Grumman.

To offset that is the comfort in the summer. An aircraft cockpit is like a
solar oven, and in this regard the Grumman is a real sweetie. Open the
canopy, and we are coooool. Pipers, which I use for training, are just
awful. I can't understand why people who design and build airplanes in a
hot place like Wichita, would build one without cross ventilation -- like
TWO DOORS.

and it doesn't carry ice well.

Ice -- there will be no flying anywhere near ice for this boy. The winter
here is +2C and 100% humidity on the ground, for about 4 months a year. We
routinely get carb ice while taxiing. I'll be in the coffee shop before I
risk wing ice. But thanks for the caution. The wing seems to be very
sensitive, I did notice that it flies different in heavy rains. Better get
out the wax, and make the old sweetie slippery again.

Best of luck with it. May you have many enjoyable years of flying it.

Thak you !

Duane

All the best,
Rick

Thanks (Sydney and Rick) for the info. I guess the mod is very
popular. I'd seen so many 160 hp Cheetahs that I thought they were
stock. I'm always learning something new around here!
