Meant to say, " raise the nose of the plane a foot or two" above the normal level flight attitude. Steve

Another "outside the box" idea is to raise the nose of the plane by a foot or two. That would certainly get the master cylinders to the highest point in overall hydraulic system. One might then have

This is all rather academic and I don't like the concept of discarding papers merely because of their age. As a Canardian I am more concerned as to the affect of these 'new' fuels on my aircraft and

Thinking outside the box there Chrissi. The problem is that the lines are routed thru the fuselage and attached in numerous places. Don't see any way to reinstall the system as an assembly

I have the infinity retracts so my highest point in the system is just above the trunnion where the gear swings. My master cylinder is in the plans position. I pressure bleed my brakes, even with

Marc, I know this is a really dumb question but I'm going to stick my neck out anyway and ask, if using a pressure bleeding system where no pumping or actuation of brake apparatus

Hard to trust reasoning that is completely wrong headed. I noted that TEL *damaged* 1920’s metallurgy (as still made into the late forties), whilst two of the papers cited dealt with engines in

As metallurgy has improved since the 1920’s the valve/conditioning justifications may no longer be relevant. And perhaps it was bullshit back then too! Hard to trust corporate backed profit driven

I just saw this discussion. Has there been any data on the effects this new fuel might have on our epoxy tanks? Jim

Hardly zero evidence of lead bromides being significant in valve seat lubrication. Take a gander at; Godfrey, Douglas, and Richard L. Courtney. “Investigation of the Mechanism of Exhaust Valve

Evidence either way is elusive. Personally, I believe there is more evidence to support banning fast food, anti-freeze and vaping as an environment hazard, but alas they have staunch well funded

About two weeks ago, canard pilot and friend Petra Sobotka was killed on the job flying a crop duster. Some of you may remember she came to Kanab, RR, Oshkosh and several other Canard events in the

None of those documents seem to address the questions of what will replace rhe function that lead provides for…. yes, octaine/compression is critical, but if the lead was always optional, the why

Hi Marc, please be careful with statements like “identical octane level”. Superficially, this may appear correct, but even fuels like 100/130 and 100LL, despite being nominally the same are NOT

Folks: I have to believe that we've discussed this in the past, but it bears repeating. A customer's plane has been beating the crap out of me for the past 5 hours of paid work time (and I HATE

Folks: During the discussion after my presentation at the Columbia Fly-In, the topic of Fuel grade requirements came up (I have no idea what tangent caused that, but whatever). Given the new 94UL,
