| Subject: | Fuel Level Senders |
Bear,
Kelley Monroe and I put in the bladder tanks last winter...of course winter
covers most of the months here in Minnesota, but I digress.
Kelley spent countless hours trying to solve the host of issues concerning
accurate fuel gauge readings.
The chase started with the correctly sized resistors at the sending units;
the calibrating of gauges through the known fuel levels...drain and
measure...drain and measure.
He spoke repeatedly with the bladder designer in AZ...and the manufacturer
of the sending units...this is not a foam in the tank issue.
We considered preparing an article for the Red Star but did not get it done
yet...your inquiry may be a good reason to formally write about it.
Bottom line, I have come to accept that the fuel gauges provide me "notice"
of "you're at 20 gallons and dropping" per side readings.
I have not and cannot get the sender to provide me with a real time reading
from the top of the tank to "bingo".
Kelley is in Chicago until Monday and thus off line. When he returns, I'm
sure he will add and correct (encouraged) my posting.
I love having the longer range tanks for the peace of mind factor...and you
will as well.
Merry Christmas to all Yaksters

Who out there has the new bladder tanks in their CJ? What fuel senders are
you using? Are you having any problems with the foam causing incorrect
readings?

If you opt for a fuel flow instrument, like for example the JPI FS450G.-
Once you have the K factor calibrated, you will know within less than a hal
f gallon of the remaining fuel in both tanks.- ANY fuel gauge should be c
onsidered only an estimate or approximation of the remaining fuel in the ta
nk, including the CJ's fuel instrument as well as the Yak 52's fuel instrum
ent.- The JPI will not only display fuel remaining, it will display the f
uel flow at the current power setting and the time to empty at the current
fuel flow.- Interface it to a GPS, including a portable GPS like a Garmin
396 or 496, and it will also calculate fuel required to destination, fuel
remaining when you arrive at your destination and finally miles per gallon.
- With Miles Per Gallon, you will see precisely what affect your throttle
and prop control positions have on MPG at various altitudes.- This I fou
nd to be one of the most valuable additions to not only Yak's and CJ's,
but to any airplane.=0A=0ADennis- =0A=0A=0A=0A=0A_______________________

Dennis' solution is the best way to go.
We have the fuel bladders on our Yak 52 in France.
There's no simple (affordable) replacement for the original fuel gauge
system (senders + device).
The original fuel gauge system (at least on the Yak, I don't know about the
Nanchang) is of high quality.
It does NOT work on a capacitative basis.
We've looked for a decent replacement, and the best that we could find of
the same quality would cost more than 10000 euros (more than 12000
dollars?).
Only my 2 cents,
Jan
PS: for those in Europe who might wonder and ask: the installation of these
fuel bladders on our Yak 52 has been discussed with the Yakovlev Design
Bureau.
YDB agreed because there's no change in balance.
The restriction YDB imposes is to not have more than 120 liters when flying
aerobatics.
The French authorities agree with the Russian point of view and so they
accepted it as an exception for our plane.
This does not mean that it's allowed for everyone in Europe (not even in
France) to install them without asking.

Hi Todd,
I don't have a prop to offer but I do have a brand new Whirlwind Large (19"
dia) composite Spinner for a three blade prop. It is my spare spinner and
its comes standard with a smooth primer finish and ready for paint. This
spinner can be adapted to most any 3 blade prop/engine combo. Whirlwind
sells is for $1350.00.
I will welcome a fair offer.
If interested, please contact me off list at cd001633@mindspring.com
Thank you,
