YS 160DZ

I have parked a couple of pictures on RCuniverse of what I am using. These
pictures were taken by me of the Japanese models at the recent CAOCC event.
I have a stack of pictures on my hard drive I only need to find a place to
park them on the net so that everyone can enjoy them.

One of the pictures shows how most of us crimp the fuel line. The clip
remains on the model. As soon as you land you lean only and engage the
spring loaded clip. You can't loose it and it is always there. No more
excuses for flooded engines. I normally leave mine engaged until the engine
fires and then I disengage it. 

I have also posted a picture of a prototype Hatori exhaust which is very
short. This is a great solution for people who have to remove their pipe
when disassembling models.

Merry Christmas all

Another you  guys could do is put fuel tubing over your hemostats, that way
you would have a less of a chance of the hemostats, ripping your your fuel
tubing!

I'll throw my two cents in.....
Like Troy said, I use the Tettra ball valve (non-filtered)  ( I run a stand
alone filter separately).  My setup consists of a total of 4      90 deg
Tettra elbows; one two way ball cock valve (nonfiltered); one YS check
valve; and two fuel filters.  

I set my fuel tank up with a standard two line system.  I then run the vent
line from the tank, out of the side of the fuse via one 90 deg elbow, then
insert the check valve (so air can enter the tank and not allow fuel to vent
out if you have to turn the plane over) then run it back into fuse via a
second 90 deg elbow.  Then I continue the vent line forward to an
inconspicuous location and cap it off with one fuel filter to allow the tank
to vent and not allow any debris to enter the vent line.(I fly off of
grass) 

For the pick up line, I run it to a new exit hole just above the exit hole
for the vent line via the third 90 deg elbow, then insert the ball valve
then back into the fuse via the fourth 90 deg valve.  Then proceed forward
with a fuel filter and onto the engine.

To fuel, just simply plug your fuel jug to the line immediately behind the
ball valve and then remove the fuel line behind the check valve to vent.  (a
little tip: I space my holes approx. 3 in. apart for the elbows, and I put
the "vent elbows" on the bottom as to not allow the overflow from the tank
to run on the ball valve.)

Now I know some of you may not like this setup....ie.  doesn't make for the
"neatest or cleanest looking" setup...... you have to drill 4 holes into the
side of fuse, etc.  But, what I do like is this:  There are no fuel dots to
lose!  Also, as we all know, YS's can be a bit balky at times with flooding,
especially in the Summer!  With this setup, you can easily turn the fuel on
and off as you please.  And you can also see any bubbles / fuel flow coming
through the pickup line heading to the engine. 

I know there are lots of setups that work just as well and are perhaps
easier and certainly cheaper, but this setup has never let me down. 
Opinions will vary, but I like it! 
Anyway, enough rambling.  
I would like to wish each and everyone of you and your families a very Merry
Christmas and a Happy New Year!  I hope Santa brings you all that you wish
for!!

Yes Jaz they work well also.

I know that K+S makes them for Heli use. These are excellent but I have not
found a really good source for them. I have a handful of them.  They are
better than the hemos. 

I just came up with a solution that works and have stuck with it. It works
great and I never have had flooding problems....It makes it a plug and play
situation. I know Tettra makes a "ball" valve that can be closed. T-Bone
uses this and others too. I have not tried one as the results if it fails
are a pain. Its almost impossible to have a fuel plug fail The worst thing
is in 4 years of using this setup...I now have 3 fuel dot sockets that are
missing the plugs. One plug is at Triple Tree I'm sure eaten up by the mower
by now. One plug is at a NATS practice site " Cocamo" or something like
that. And another was lost in California at a contest. I usually toss the
fuel plug "dot" into my pocket and upon landing re-install it.  This keeps
me honest and I don't loose them.

Granted the type of Hemos you choose will make a difference. I had my lovely
wife get some good ones from the hospital and they won't damage the fuel
lines either. I think they are Vascular clamps not positive....But
regardless The plug in the line is better in my opinion. I tried the clamps
and was always banging them against the side of the model. The plastic
keepers as Jason points out work well also...

I just found something I really like and use it.

What about those plastic fuel line "pinchers"...? They use them on pylon
racers but I forgot who makes them.
