Shouldn't be required for that grade of aluminium. Mine have been exposed to an aggressive coastal environment, unpainted and untreated in all respects,...Leave a comment:

I would not recommend flying a -540 engine without sealing the front of the baffles, I would expect overheating. There is also a lot of extra drag if...Leave a comment:

In which case, there is no known problem from Murphy Aircraft with using fuel sight gauges to connect the cross vent system. -
That is interesting, thanks for sharing!
Again, they have been unable to come up with hard test results to prove what was happening, and were forced... -
It would be good to know what the issue was....Leave a comment:

Jon - you have to admit, it's a big assumption everyone here is making. We have no firsthand sight or knowledge of the investigation and determination... -
I was just kidding around.
It depends on the gross weight for the class divisions, so for instance anything 1,500lbs gross to 2,500lbs gross...Last edited by Battson; 02-09-2020, 04:08 PM.Leave a comment:

If anyone videoed it, I couldn't find it. I shared the stills on the BH Facebook Group. -

I understand you are not a 'gravity feed' fuel system if you need pumps to keep the engine running. You are pumped. In that case, you run the risk of... -

Not impressed by the distances?? :P
We fly as light as possible.
If you can land your 4 place in 150ft at gross, then call me...Leave a comment:

So I think the conclusion is, if you have fuel injection - you NEED to install these vents to be on the safe side, or avoid unbalanced flight if you have...Leave a comment:

Sorry Jared - where are you measuring from? The Datum is all-important here, if we want to compared apples with apples across aircraft.
