You might want to get hold of one (or more) of the "flight manuals" floating around on the net. The version I have has the following:

Below is the NTSB report of Boriak's accident. I read in an aerobatics newsletter that he was inverted after the accident and couldn't get out until the canopy melted.

NTSB Identification: NYC07LA ...

But is the system only going from 40 to 55atm after the main valve is shut off (and not before)? If so then it seems there must be a leak somewhere downstream of the main valve.

The pressure goe ...

I can't recall how the Yak-50 air system is set up... If this were a 52 I'd almost think (going under Brian's theory) that the main and reserve bottles were swapped. This would account for a big pre ...

I've ordered off their ebay store and corresponded with Steve via email. Highly recommended.

There was a post a while back about brake cables. It touched off some discussion about buying from the suppliers vs. making your own. I assume 68" is standard. Here's the post:

Take a look at "An Introduction to the M14P for Flat-Engine Pilots"
by Fred Abramson. It should answer many questions:

Well, just have to toss this in. These threads remind me of this classic monty python skit:

Most, if not all, aircraft with M-14p have the quick drain. If you get a hydraulic lock (drain was closed, etc) then the only/best remedy is to remove the plugs.

Hey Guys,

I was flying f ...

If I follow the logic here correctly then you could check for either a leak or a restriction by cycling the gear on the ground. Put it up, verify the 20 drop on the gauge then if the pressure slowly ...

This is sort of interesting. They have recent sat photos of the area in which Steve Fossett disappeared. Using something called "HIT" you can scan a small section then check a box indicati ...

Here's more info. They describe it as going in "nose first" but the aircraft appears to be very intact:

Contact www.m-14p.com. They've got them and just about everything else.

It doesn't appear that anyone asserted the pilot was scud running, etc. You might be referring to the photos and captions which seem to come from the owner of a nearby property. He sort of implies t ...

Contact your destination FSDO and find out what they require. Might also be useful to cover your bases by contacting departure FSDO.

I appreciate all the input. I'm attaching a diagram of the compressor for those who are following but don't have one at hand.

Always a fun topic. So the issue is the compressor is a bit lethargic. Maybe making about 40atm and taking some time to do it. After landing and using the brakes a bit I might only have 35 when i p ...

Another photo.

A little more info. this is a rough translation from russian:
