| Subject: | Re: CJ Nose landing gear brace |
I have not got into my landing gear yet and reading my Manual and looking at the
Parts manual, this how I interrupt the PT-6 Manual. On page 2-4 Fig 5 (for the
Nose Gear Brace) Detail B it gives you 2 dimensions.
1: 5 (+3) is for the Eccentric (off center / out of round) limit for the bearing
surface, I do not believe it is in MM either. Since I see no bushing in the
upper and lower Brace I assume that the parent metal is the bearing surface
so its a pass/fail inspection not an adjustable dimension.
Page 2-3 Par. 2.8 It allows the Ball Bushing (lower bearing attaches to strut)
to rotate in the joint not more than 686 N.cm. Also it allows it to rotate Deflectively
Not real sure what they meant but I think its the side to side limit.
Then the Clearance limit is for the bearing ball to the brace bearing surface.
2: The other clearance of 0.05 0.15 mm is the down and locked dimension which
is adjustable by adjusting the rod end of the actuator. This dimension is taken
between of the forks of the upper brace.
3: On page 5-6 Par 4.1 you can test you actuator for the proper stroke of 333
+/- 2mm as well as pressure/leak test.
I hope I helped and of course if I am wrong, I hope someone will help us both out
with their lessons learned.

Good picture.
But I am at a little bit of a loss. I asked whether Vectorwarbirds
would make hoses and fittings for putting in any of the oil shutoff
valves that you sell, and your answer was that it was too hard to make
kits for so many different kinds of aircraft.
So in order to avoid this kind of disaster down the road, could you
possibly suggest a good place to have hoses made that would connect to
the existing M-14 engine and also to your various types of shut off
valves? Would Kevin Kimball be a good person to go to?

Mark,
Any good aviation supply house can make hoses. I think you can even order
them from Aircraft Spruce giving them the length. The real problem is th
at the valves come with an AN-12 (U.S.) outlet hose fitting and our engin
es have a metric fitting of basically the same size but different threads
(metric) on the engine. We in turn use the stock hose or new US hose, le
ave the stock metric fitting on one end and then shorten the hose to fit
as the new valve makes this necessary and then install a new AN-12 hose
fitting that now mates to the valve. So metric on one end and AN on the
other.
Its not really a lot of trouble but you do have to know how to make up an
aircraft type hose. This means purchasing the -12 hose making mandrel so
that you do not cut a flap of rubber inside the hose and cause it to clo
se off. The hoses from the tank to the engine are not under pressure so
they are not prone to leaking, so really the type of fittings and hoses
we and the Chinese use are overkill.
If I was most and had basis mechanical skills, tools and knowledge I would
buy the mandrel and parts I needed and make up the hose myself as its not
really hard. Also of note is that you can use U.S. AN -12 Aeroquip 303 ho
se with the large Chinese fittings and we have done this many times. But
its about the only hose you can use with them.
Trying to make up a general kit for such a limited item (I have found most
people won't invest in excellent engine mods over gadgets in the cockpit)
is not cost effective given the many different Russian aircraft types so
we just don't do it. So as I said you must have some pretty good mechani
cal abilities or take it to someone who does. But in my personal opinion
and experience the oil tank shut off valve is one of the best mods that
can be done to the radial engine bar none.
Also of note is that our manual valves do not come with the operating cabl
e because people put it in so many various places because of gagets they
have installed in the cockpit, so trying to have a standard install acros
s the board just doesn't work. So once they figure out where they can ins
tall the push pull cable they just buy it from AC Spruce. The last one we
did we put the cable handle just in front of the stock starter switch (Na
nchang) so that when the valve is shut off the cable handle is up in front
of the starter switch blocking it. Also there is a starter interlock swi
tch on the valve so that it will not start unless the valve is fully open.
Thanks for your question and if I can be of help just let me know. But I
encourage everyone to install a shut off valve, its very cheap insurance
over buying a new engine or having one fail because of hydro lock and it
also saves oil. Bill Blackwell has installed many of these valves so he
is the best go to install guy I know.
Cheers and safe flying!

Thank you for this well thought out and accurate answer TGB.
Your answer gives me, as well as everyone else, a clear picture of the
issues at hand.
Kevin Kimball sometimes reads this list, so I will take a wild chance
here and post a question to him that maybe he could answer.
I notice that Kevin Kimball Enterprises sells a kit called the M-14P1
that converts all the M-14 fittings to accept AN type hoses.
Can KKE sell just the adapter fittings necessary so that a person can
run a complete AN hose from engine to oil tank, with AN fittings every
step of the way. From engine, to shutoff valve, to tank. ALL AN
fittings? No metric to AN hoses necessary???
Thanks,

Mark if I remember correctly you have to buy the whole kit from Kimball
to convert. But that might have changed. I have converted my AC to all
AN pretty much. Just makes it easier done the road. I just bought a AN
-12 nipple and had it welded on the stock inlet tube, pretty easy.

| Subject: | Re: CJ Nose landing gear brace |
Looking back over the info in chapter 2 I see the .05 -.15.A small feeler gage
should tell the story. Measurement is done with no air pressure I believe.
K
Seems to me that there are three ways to hold the gear down in in order of priority
1. The locking pin/ball in the actuator
2. air on the system
3. NG brace over center
My guess is the reason for the small tolerance is to get the brace over center
but not enough to close that gap and bend something when the air is on.

Dennis is correct, partially. I used Kimball cutoff valve but had an
aviation grade pump built for the sump. I have pictures and will post
them when I can recover them from a computer in my hanger. When I have
my valve closed, the air start button will not operate because of a
micro switch set up. The only way it the prop will turn is if the oil
shut off valve is open engaging the micro switch. I have seen Girt's
photos and my set up is a bit different. Works nicely and reduces the
oil from leaking out the exhaust, etc. I notice little if any oil on my
belly after a flight now. Oil loss/consumption is down as well. Girt,
how you doing?

Set up at 2250 RPM and 75 MM manifold pressure, entry speed for a loop is
165 kts. with a 3-4 g pull. For aileron rolls, it's 135 kts pitching up 20
degrees before rolling. Don't know about hammerheads although I would
imagine 165 kts would be appropriate. Snap rolls are not recommended.

The TW does not seem to have the same layout in some regards, so we had to
make some interesting bends.. but I burn less than a quart an hour flying
hard acro these days.. so I am pretty happy with the whole setup.. I plan
on replacing the scavenger hose with something a little more rugged, but
quite frankly, it works great.. lol
Will see you at Waycross GoatBoy.. looking forward to flying more this

| Subject: | Re: Acro Speeds for the CJ |
Those speeds mentioned will surely give you more than enough smash to do both those
maneuvers comfortably. Once you are comfortable with your plane the speeds
can come down. You can loop the CJ no problem at 250 clicks. I like to use 280
and 3.5 to 4 g's. The hammerhead entry is fine at 280 clicks but sometimes
I like more speed to give me a few more seconds trying to figure out if I'm purely
vertical. The hardest part of a good hammerhead is the speed to kick the
rudder and push fwd and left stick. (Don't do a hammerhead to the left unless
you are comfortable spinning the CJ or tail sliding). I've occasionally done
my patented hammerspin in either direction. It's not a pretty sight. Also, I've
found the CJ (at least mine) has great pitch authority at very slow speeds.
Try pointing it straight up and as airspeed hits 100 clicks pull straight back,
it'll swap ends nicely. Barrel rolls I use 280 clicks and a rolling 1- 1.5 G
pull and hit 45 nose up 45 degrees off heading continuing rolling to 90 degrees
off heading with the nose inverted on the horizon then 45 back at 45 nose low
hitting the horizon again as I level the wings back on the original heading.
(Navy method). Immelmans and 1/2 cuban 8s are the same speed as the loop. For
an immelman I prefer to be a little faster because the plane is so god awfull
mushy in the roll at the top.
I suggest not much more than 11L of oil if you are going to beat up the overhead
stuff (especially hammerheads) or you'll have a lot of cleaning to do
~Wiz
A four point roll (never pretty in the CJ? needs closer to loop speed and more
nose attitude than 20 degrees on the initial pull up/

Bill Blackwell set this up for me years ago and I was either the first or

helicopter. This was a monstrosity that had 2 W1820s mounted on each side.
"A flying transmission system built for failure". These valves were used
for the same purpose. Evidently Bill picked these up from Davis-Monthum.
I don't remember if Bill ever set this up as a kit or not.

| Subject: | Re: Acro Speeds for the CJ |
Not a good idea to do whip stalls/ tail slides. The CJ's tail really isn'
t built for it. Be careful with Hammerheads. The CJ does not like to per
form them very well. To the right only and you want to lead early with ru
dder before she stops flying. You sort of fly around the corner.
Be careful with spins. The other day I was up with full tanks (I have the
big tanks 59 gals), a good 200 lb GIB with chute. During spin entry, I
left the power on. She was spinning nicely, after 2 turns, when I releas
ed the back pressure - the stick stayed in my stomach and she continued to
spin. After about a 3/4 turn I pushed the stick forward, noting it requi
red about a 2 or 3 lbs of force. With the stick neutral and opposite rudd
er, she recovered nicely. This was the first time I've ever encounter a
flat spin in a CJ.
Checking with a guy who did spin test for the FAA and the Aero Shell guys,
it seem you'll get yourself into a flat spin by leaving the power on duri
ng the spin. More so if the C/G is well aft. I had done my little routin
e- which I normally do at a set power setting. I had added the spin at
the very end and forgot to reduce the throttle.
I normally enter my barrel rolls at 135 to 145 kts. Four point rolls abou
t 150 kts, starting with nose up about 20 degrees. It seem to prefer doin
g them to the right. I don't normally do snap rolls, but I slow the airpl
ane down to below 80 kts before executing.
Always do a good preflight inspection before and after the sortie. Make
doubly sure things aren't running lose in side. You really never have to
pull more than 4 Gs to do any maneuver. And it's a very good idea, to ha
ve someone with you on that first flight, who's done acro in a CJ before,
particularly if you're a FNG. :-)

Subject: Re: Yak-List: Acro Speeds for the CJ
Set up at 2250 RPM and 75 MM manifold pressure, entry speed for a loop is
165 kts. with a 3-4 g pull. For aileron rolls, it's 135 kts pitching up
20 degrees before rolling. Don't know about hammerheads although I would
imagine 165 kts would be appropriate. Snap rolls are not recommended. ..

| Subject: | Re: CJ Nose landing gear brace |
I intended to get the book out and reply to this today but did not get
there. There appears to be some mis- conception on this subject.
There is only one function that positively locks the gear down. That is the
over center position of the drag link ( landing gear brace in Chinese
terminology).
The ball lock in the actuator is there for the sole purpose of maintaining
the drag link in the over center position. This serves the same pupose as
the over center latch on many US gear systems and, if I am not mistaken,
also on the Yak 52.
All of the gear up load applied through sideways motion or rough ground is
carried directly through the drag link not through the actuating cylinder or
the ball lock.
In fact, if the nose gear ball lock (in the CJ) were to fail, rough ground
and bouncing could move the drag link out of safety and collapse the gear.
The extended piston rod would end up looking like a pretzel even with full
down air pressure.
The over center measurement of 5 to 8 mm ( 7/32" to 5/16" ) and the contact
surface clearance of .05 to 1.5 mm (.002" to .006") are both established by
adjustment of the actuator piston rod fitting.
If all set up and working properly the gear should be safe with no air
pressure.
Walt

| Subject: | Re: Acro Speeds for the CJ |
Pappy,
Good clarification on the tail slides. I wasn't advocating that it should /could
be done. I would NOT do one and would avoid them at all costs with that skinny
long aft fuselage.
I disagree with the 4 point roll and 20 degrees nose up. I find order to hold it
at each point, defining the maneuver, the nose will be buried by the time you
get wings level. Then again I don't like to stomp on the top rudder or push
when I'm inverted. The dihedral wing is just punishing.
I agree about leading with the rudder before A/S decays for the hammerhead and
I find the CJ likes them just fine. It's only when you are off the vertical that
it gets sloppy. Gotta learn to be patient as the turn starts slow and accelerates.
If you don't feed in aileron and a little fwd stick it wants to go over
on it's back.
Interesting about the spin. I would say we all have some pretty random
CG's with all our Mods not to mention the removal of all the original gear and
it's up to each individual to get a proper weight and balance before launching
into any acro. In any case, gutsy move spinning in that configuration.
Absolutely, no loose gear and a good FOD check is in order.
I've got many hours and more than enough in fighters and I spent more than a few
flights with an experienced CJ guy in the back before I felt comfy.
BTW, what the hell is a whip stall?
