Posted: Wed Oct 18, 2006 2:20 pm Post subject: Who sells instruments?

I'm setting up the panel now on my  F51 project so the subject of instruments

 came up. My Housai engine will need  at least a tach, oil temp / pressure gauges.

 Anything else recommended and who  sells these gauges please? Anything sitting

 on a shelf gathering dust in good  serviceable condition? I'm in the market for decent

 flight instruments too. I see what looks to be a tach generator sticking  out from the 

 air start distributor.

  

 I've a starting procedure question  too. After you've pulled the prop through, primed etc. 

 you hit the starter and that engages the air solenoid and  shower of sparks ( incorrect 

 name I think) simultaneously. As the  engine begins to start, the mags get switched

 on and briefly the air, shower of  sparks and mags all are engaged together. Do you

 normally need to have your left hand  free to play with the throttle through all of this ?

 ie, would it be very important for me  to configure the starter button/switch and mag

 switch to be activated with only one  hand during the process? Thanks.

Dave,

 I have  all the engine and pneumatic instruments you might need, also valves, etc,  etc.   If it's in a CJ I have it.

  

 Actually having 3 hands would be handy some times.  I'd configure it  somewhat like the CJ or 52.  

  

 

Always Yakin,

My thoughts exactly. Put the shower of sparks/airstart button just to the right of the mag switch. Configure the mags to switch out board so that when the engine fires with the thumb of your left hand on the button you can flip the mag switch outboard with your middle finger. If you prime the engine and pull atleast four blades after priming it and cracking the manifold/throttle lever (Russsian term "the advance"), you will not need to jockey the throttle to get her fired.

David;

  

 Doug Sapp will have a tachometer to match the  tach-generator on your Huosai. If you wish to use a triple guage for oil  temp/fuel press and oil press rather than individual guages there are  options.

  

 1. The Chinese/Russian guage requires two matching  firewall mounted transmitters to convert oil and fuel pressure to an electrical  signal for the guages.

  

 2. The standard AN triple guage has direct  reading pressure guages. These should be connected using MIL   H  8794 hose (Aeroquip 303) for long life. I have found these  much more reliable than the

 Chinese/Russian units.

  

 Both types use a Wheatstone bridge circuit for the  oil temperature with a matching probe sending unit (different of course for AN  or Chinese).

  

 The Huosai uses auto advance mags so the ignition  is set to BOTH for starting. The M14P uses a fixed spark mag so ignition is  energized after the boost coil (not shower of sparks) start.

Giday Doug. Thanks for the note. Walt  Lannon said in his note that the 

 Huosai does not need a boost coil  like the M14P so why would three 

 hands be a good thing? Not trying  to be smart here...just trying to  understand. 

 Steve Culp sold me a boost coil knowing full well I was  installing a Huosai 

 engine so I automatically thought  about the positioning of the  switches.

 Unfortunately, I've never seen the  inside of a CJ or Yak cockpit.

  

 Are your instruments of Chinese or US  origin? I'm trying to keep this project

 looking as original as possible as a  1930 replica. Chinese markings

 on the panel may detract from this  but of course we have to consider compatibility

 of the connections etc. If you have  engine instruments which might be useful 

 for the project, please say condition  and price etc. I'm ready to deal.

dave,

    

   Actually the HS6 has a booster coil on it also (usually mounted on the engine mount on the left side).  The difference in starting procedures between the M-14 and HS6 is in the mags not the coil.  If you start the M-14 with the mags on "1&2", she can easily kick back during the start.  This sometimes shear the coupling on the compressor (the most likely to happen - too me anywa  y).

David;

  

 I did not say that the M14P does not use a boost  coil. All of these engines do. I tried to point out that there is a difference  in the mags that dictates different start procedures.

  

 I mentioned boost coil only to advise you that it  is not a shower of sparks system.

AAAAh. Now I'm starting to understand. The  Huosai uses a booster coil ( and earlier I wrongly 

 stated that Walt Lannon said one was not necessary) as does the M14P, but  because of the 

 auto advance features of the Huosai mags, ...ie ..retard at zero to low rpm,  the Huosai mags can 

 be turned on before the boost coil/ air solenoid switch is engaged. So,  ..I guess, only two hands 

 may be needed if one is required to frig with the throttle for any reason during  startup.

  

 Sorry to the list for this quasi off  topic drivel and thanks to all who have contributed advice. 

 It's not easy building something from  scratch, but the Fairchild 51 has some significant position

 in early aviation in Canada and the USA. The  advent of a reasonable cost 285hp radial makes

 things like this an achievable  proposition and I'll likely be the only one on the planet flying  one.

 Besides...who else will be able to  fly in with more beer than you guys  can drink, eh?

  

 Anyone with aforementioned  instruments for sale, please contact me off list    dstroud(at)storm.ca (dstroud(at)storm.ca)

 Thanks.

Unless you have the proprietary TSO'd CJ Parking Brake mod, or have the a/c chocked, you will need a hand on the throttle, the start button and the brake handle (unless you have a very large, multidextrous left hand!).

Hi David

 You DO need a boost coil with a Huosai because  there is no impulse coupler on either M14 or Huosai mags. You start the Huosai  with both mags on. It will not start in reverse like the M14 because of the  advance in the mags. If you have chinese mags start with both mags on. It won't  start without the boost coil.

Guys  

Do you mean to say that you should only start the M14 with one mag? ….not sure if anyone does that hear in OZ

David Stroud......contact me off list (mlbjr(at)earthlink.net (mlbjr(at)earthlink.net)) to discuss American  instrumentation for the Housai Engine.  And yes, you can hand prop the  engine w/o the shower of sparks operating.   Marcus

Although it can be started on one mag, it should be  started on both mags.  I have started the M14P with standard M9F  magnetos and a bad booster coil wire.  Here is how I did it.  Prepare  the engine to start as you always do including pulling the prime through about  3-4 blades.  Then start the rotation with the air start as you would  normally do.   When the rotation reaches its max speed, flip the mags  on to 1 + 2.
