So the real question is: what is the true necessary throw for all controls
?? (This is for us that build our own control quadrants :-)
Can someone provide the linear control throw for:
Throttle
Propeller pitch
Mixture
thanks !!

Dan,
Way to go. Another super tool for RVer to use.
I used it to check on the RV accident. If you remember, I camped beside an RV-4
which crashed on the way home from OSH this year. Anyway, the plane was out
of gas, even though, he stopped and got gas. Below is a part of the NTSB report:
Fuel receipts were obtained from locations along the pilot's route of flight. Based
on these receipts, it was calculated that the newly installed engine burned
approximately 11.5 gallons of fuel per hour. The total fuel capacity of this
airplane was 32 gallons, of which, 26.7 gallons were usable. The pilot purchased
24.6 gallons of fuel in Iola, Kansas, at 1343.
WHERE DID THE NTSB GET THE USABLE FUEL OF 26.7 GALLONS? I seems to me that a half
a gallon per tank is trapped is much closer or maybe 31 gallons usable. What
say you RV-4 drivers?
Is this just a typo or does someone need to question the NTSB as to where they
got their numbers?

Either I cannot divulge where I got my information, or not sign my name to
this, but................. My RV-4 w Lycoming IO-360 had 32.2 gals of fuel
capacity when calibrated after the tanks were emptied. I was approaching my
destination airport about 1 1/2 years ago when the "6 P's" caught up with me.
And while it "was" Ph-leur of Pressurized Ph-uel Ph-lowing to Power Plant!
The real cause was Piss-Poor-Planning-Preventing-Proper-Performance. Enough
said! I did discover incidentally, that when you reach best L-O-D airspeed,
and lower the attitude from the cruise A-O-A, that the remaining 17 ounces of
fuel do ignite, and restore your confidence for about 44 seconds.
Fortunately, that few seconds made the difference, and I made a very nice landing
about
one-third of the way down the runway. Hoping that no one noticed that the
prop was stopped vertically, I let it roll to the turn off, and made it about
50' short of the fuel depot. I quickly jumped out, pushed the airplane into
an appropriate position, and grabbed the hose with an intensity that was
approximate to my blood pressure. Soon, the pump indicated exactly what I
suspected it would, 32.3 gallons. I am convinced that the RV fuel tanks have
very, VERY little unusable capacity. So, now that I have bared my sole, where
do
we go with this? And are there any other's out there who are willing to
sacrifice their reputations to validate my claims? I will let the proper
authorities know about this event--hopefully anonymously. By the way, I am pretty
sure you are referring to an accident that happened to my friend from a very
nearby airport. Like my father told me, don't do as I do, but do as I said
to do, Les Featherston

You are a very brave man, Les. And, since there is no such thing as luck,
very fortunate.
A similar incident (not about fuel though) happened many years ago when a
charter pilot flew above cloud over some very high and rough mountainous
terrain when the single Comanche's engine lost oil pressure and eventually
quit. They glided into the soup with the passengers praying and some near
panic. There was nothing else to do but wait ... at best they would descend
into a valley. He knew the mountains were engulfed in cloud. So, they sat
there in eerie calm waiting for the windscreen to suddenly fill up with the
side of a mountain. When they broke cloud at about 50' above ground, they
were on final approach to a local farmer's private dirt strip on top of a
plateau. The pilot dropped the wheels and landed. They, too, were not
lucky -- they were fortunate.
There are two kinds of pilots. Those who practiced the 6-P's and those who
will.

Les,
The accident I am talking about is N7XD. It was a man and his son who
parked beside me for this years OSH. I was with his wife who stayed another
day at OSH when she heard the news.
I have written a letter to the NTSB today so we will see if they say
anything. See below.

Subject: Error in the Accident Investigation Report NTSB
ID: FTW04LA199
Location: Collinsville, Texas
Model: DRZYMALA RV-4
ID: N7XD
Sirs,
I believe I found an error in your "Factual" report on the N7XD accident.
Quote:
The total fuel capacity of this airplane was 32 gallons,
of which, 26.7 gallons were usable.
Un-Quote.
While the total fuel capacity of 32 total gallons is correct, there is no
way that the 26.7 gallons usable is. As a RV builder, I have never heard of
a case where even one gallon per tank is un-usable. The worst case would be
30 gallons usable but more likely a number closer to 31 is correct. As fuel
is a major factor in this investigation, I believe that the correct amount
of usable fuel is important.
As a side note, I am the owner-pilot of the Harmon Rocket II (N561FS), an
RV-4 with a bigger engine, parked beside the RV-4 at OSH and was with the
wife when we heard the news.
Thank you,
