Hi guys,
can anybody tell me if a second air bottle could be fitted in series
with the existing 11 litre bottle
in the rear of a 18T, or possibly a larger, say 20 litre bottle.
My problem is that I can only store 40 Bar and unless I catch it on the
first few blades ( still learning how much priming to give her) I barely
have enough air for a second attempt, and It occured to me that 40 bar
but 20 litres capacity would solve this problem.
Also I think I remember reading about somebody making carbon fibre high
pressure 1000psi vessels to replace the Russian units in the USA,can
anybody help on this subject.
Thanks & regards

| Subject: | Yak 50 priming drip |
Guys,
Thanks for all the input. My usual procedure is to prime and
pull through on first start-up. We noticed the drip while doing
an annual with the cowling off. I hadn't noticed it before. We
weren't starting up, just looking for things
like...well...drips. The drip was on priming, not pressurizing.
Tim,
I've had my 50 for a year and a half. I bought it from Michael
Lloyd. Some years back, I also had a 52.

John,
You got a nice bird from Freezer. (Lloyd). We hated to see him part with it but
glad it stayed here in the states. (he has a beautiful Glasair III now) We recently
had a Yak-50 go overseas!
Welcome to the -50 community!

Bruce,
If you're only storing 40 ATM's, the pressure relief (pop-off valve) is
the problem. Not the size of the tank. Adjust the pressure relief
valve to release at approximately 55 ATM's and it should shut off at
around 50 ATM's. There is more than enough air in the existing bottles
to start the engine. Before you hit the start button though, try
putting in 4-6 shots of prime, THEN get out and pull about 4 blades,
putting the prop on a compression stroke. Then go back inside the
airplane, repressurize the system side, pump 2 more shots of prime,
stroke the throttle 2 full strokes fore and aft and then move the
throttle to about 1/4 to 1/3 open. (Do not touch the throttle again
until after it starts.) Now hit the start button. The engine will
typically start on the 1st or 2nd blade. Use the primer pump if the
engines needs more fuel. Do not pump the throttle.

Bruce,
The short answer is yes, your can place a SCUBA tank in line, many guys
here have such a installation. But the reason they did it is not
totally the same as yours. They did it so they could have air not only
for themselves but also for anyone else who might be having problems.
They carry a soft line long enough to reach to a aircraft parked beside
them.
The long answer is there is something wrong with your starting procedure
or your equipment. I can get 5 to 6 start attempts before I am down to
the critical point which is about 16 ATMS. You may have a leak in your
air system. How long will your 40 ATMS last if you just open the main
air valve and walk away from the aircraft?? Minimum acceptable is that
it should take over night for the air to leak down. Another thing might
be that your QDF-1 valve may be going bad. The one in my aircraft would
not "pop" below 40 ATMS of air pressure. I changed it out and now it
will pop and very slowly try to turn over the engine at 15-16 ATMS of
pressure. The only other thing might be that you have a leak in the
start system somewhere. Check you hose from the QDF-1 start valve to
the start spider on the engine. I am assuming that you have good
compression, excessive blow by and leaky valves will cause problems
also. If your timing on the start spider is not correct you just might
be loosing air there also, does it turn over properly when you to to
start it? Or is there a lot of air noise in the clys?
Hope all this helps. I carry the above valves and hoses in stock if you
should need them. I also have all the wheel and brake parts.
Always Yakin,
Doug Sapp

| Subject: | Yak 50 priming drip |
I've flown three 50's and have never seen that happen, including the 700
hours or so I have in mine. I would take a hard look and make sure it
is not a case of it leaking somewhere else and then running down to the
lowest point and then dripping. Start at the priming hose itself,
especially at the fittings at the end of the hose itself. Then where it
connects to the manifold tube area. If you do not see it there, my
guess is that you should look at the lowest intake manifold tube and
look for a loose oil drain cap. I have an oil drain kit coming from the
low cylinders that puts a fitting and #4 line into each of those drain
caps. When I prime, the fuel runs to that lowest area and then OUT of
the drain itself. If I leave this drain closed, ZERO fuel comes out of
anywhere. Thus, I suspect you've got a leak in one of those caps, (or
lines if you have this mod, especially if you are using solid aluminum
tubing which was what was used by some people that installed this mod,
which is NO GOOD AT ALL!).
I'd advise you to not ignore this leak. It is not a good thing, nor is
it normal... No offense to Dennis meant.

| Subject: | Yak 50 priming drip |
Sorry to disagree gents, BUT! I have primed the snot out of my 50 and
have NEVER had fuel leak out of the bottom of the engine. Out of the
exhaust ... Sure... Especially when priming and then pulling the prop
through. I've had it come out of the intake drain lines especially with
the drain kit installed and the valve open.
I have even had it come out of a CRACK in one of the INTAKE TUBES (hint
hint).
I disagree that it is normal under any condition. Take a look at how
this system works. It would have to get down, back out the blower, and
then down to the carb to come out.

I have had it when priming too much. Be careful when priming. You may
start a fire. I have already started a fire once. I was very lucky to
have friends with fire extinguishers in the neighborhood. No damage
thanks to their rapid intervention! The fire I started, was entirely my
own fault, being unexperienced with the Yak.
IMHO, when the engine does not start easily, there's some problem. For
best practices, try to have someone with a fire extinguisher in the
neighborhood when starting. Of course, this is not always possible.

Mark,
Be advised, someone is doing the same thing to you. Pulling emails off
the yak-list and sending out hate mail about your business practices
under the name email name of "Mad Dog" (reminds me of what I am drinking
as I write this) . My spam filter caught it and I deleted same. Had the
sender included specifics, perhaps I would inquire further.
Gulf Coast is in my backyard and the people I worked for did a lot of
purchase and install business with them. 2 points: 1) our problems with
their installation always got resolved but (2) it took a persistent and
concerted effort on our behalf to effect that outcome. I can also say
the same about our dealings with the other Big Name shops in Florida.

Well, I can tell you what I am doing for The Project. I have replaced
the wobble pump with an electric fuel pump. I plan to use a solenoid
valve from the output of the electric fuel pump and before the
mechanical fuel pump to valve fuel into the primer line on the
engine. It will be actuated with a spring-return switch. Turn on the
aux pump and hit the primer switch to prime the engine. No more
primer pumps and no needing three arms to work the wobble pump to fly
the airplane should the mechanical pump fail.
Just another idea for you.

Of course you're right, Mark.
Nevertheless, I started a fire once, after priming too much. I still don't
know how or why, since the engine was not hot. I did not have any (known)
leaks. Since then, I always try to have someone in the nearby.
