Dennis,

Thanks very much for that. I have not got into what it looks like yet but I

suspect that it will be the same as on the Sukhoi, same designer. It is

buried on the lower portion of the firewall and as with anything else in

these aircraft it will either be really easy or really hard, there is no

middle ground )

Brian,

That is most likely the case with the standard M14P which has M9F fixed

timing magnetos that are timed at 14-16 degrees before TDC. On the Housai

(if I'm not mistaken) and just like the M14PF, both have centrifugal advance

mags and are timed after TDC, depending on the number stamped in the boss of

the magneto under the cover.

Brian, Dennis;

Not sure what this has to do with air bottles except maybe air vs nitrogen but here is my 2 cents worth; Please keep in mind that I just arrived home after an evening of pleasant conversation and too much very good rye whiskey.

Ignition Timing;

The Huosai with a 25 deg auto advance mag. is set to approx. 7 degs (CRANKSHAFT) BTDC or 7 X 0.787 PROPSHAFT. Too tired to fitgure it out.

The M14P if you were using a 25 deg auto advance mag rather than the M9F would be set at approx. 1 deg (CRANKSHAFT) BTDC or 1 X 0.658 PROPSHAFT. (Hell, I can figure that out)

Either engine will start using N2 provided that it starts in the first one or two attempts. After that there is no hope. The reason is that the starting charge (air or N2) is injected on the power stroke. Ignition takes place in a different cylinder which is picking up AIR from the intake system. If the start fails and all cylinders become contaminated with an excess of N2 then you might as well go and have a drink cause it ain't going to start no how.

Cheers;

Walt

Yes, it is an OWT! It doesn't need to be repeated regardless of how the oxygen is being used.

Walt,

The M9F mag is a fixed mag and the engine timing on the M14, according to the manual, is 14-16 degrees before TDC measured at the prop flange. On the M14PF 400 HP engine, they typically have M9-35 magnetos which are centrifigal advance/auto advance. Their timing is set based on the stamp in the boss of the mag under the cover. Most all of the -35 mags I have seen have 34,35,or 36 stamped in the boss and are timed in the 4 to 6 degree range after TDC. Here's the chart that I use when setting the M9-35 mags.

23 2BTDC

24 2BTDC

25 1BTDC (Walt, as always, it right on the money even after too much very good rye whiskey)

26 1BTDC

27 0

28 (1)ATDC

29 (1)ATDC

30 (2)ATDC

31 (2)ATDC

32 (3)ATDC

33 (4)ATDC

34 (4)ATDC

35 (5)ATDC

36 (5)ATDC

37(6)ATDC

I also completely agree with your analogy on N2 and starting.

Remember 79% of what you are breathing right now is N2

Yes that is true, but I prefer not to mix what I breath with 100LL and then light my cigar! -)

Can anyone tell me the contact name and number for the outfit in CA that can

check the air tanks?  I know this info was on the list recently But I cannot

locate it and was not smart enough to write it down.



Always Yakin,

Hi All,

 I have located a company here in the S.E. that will  hydro and visually inspect the air tanks for $50.00 each. They did my CJ  tanks last spring 

 and I was happy with the results.

 If you want FAA papers with the tanks the price is  $95.00 each.

 They will accept UPS etc. and return them the same  way.

 So price will be $50.00 each plus UPS both ways  plus FL sales tax.

 I have no affiliation with this company at  all.
