Dual Trim Switches?

Help

I flew a 'Top Hat' four way trim switch for thousands of hours and
never saw a second one. Anyone know where it was located?

Our emergency procedure for run away trim was to pull the circuit
breaker(s).



Switches like that are illegal now. You have to have passive fail systems
on trims and autopiots nowadays.

I'm going to the "Wings over Houston" Air Show at Ellington this week
end. Besides getting some cockpit time in the P-40 and P-51, I'll talk
to some of the current Heavy Iron drivers, with birds on display,
about what the trim is on the birds newer than I flew. From past shows
expect to see at least the F-15, F-16, F-117 and also Navy jets, Blue
Angels, etc. Probably some Chinese Migs that were kept at Ellington.

Its 62 years since I flew the P-40 and 58 years since I flew the P-51
so need the cockpit time to refresh where all the controls, etc.,
were/are )

Have fun!

Ask 'em if they have any LeBlond valve springs while you're there.

Have you contacted Old Rinebeck Aerodrome on the Hudson north of NYC.
They have lots of WWI birds that fly and other old airplanes and
engines. They might have the springs or know where you can get
original or aftermarket?

Also I saw someplace in my wanderings in some publication that there
is a outfit that will make springs to your specs. Ask around and look
on Internet and you may find the company.

Want to say they specialized in springs for race car engines????? so
you might follow that trail.

I'm assuming you are not worried about getting a certified engine that
old. Aren't there some waivers for parts that are no longer available
and that you can make?

I'll ask this week end if it looks like anyone can give good info and
advise.

Wonder if our 51 driver from up north is going to get gas money and
come to Ellington?

I was only joking!
Actually, there is a guy making replica vale springs. I really ought to
buy some as spares, but they;re over $100 each!

It's one weakness of the LeBLond and attempts to substitue with
everything from O-200 to Chevvy springs were abject failures. One guy
who has a few airplanes with LeBlonds and Ken Royces finally bit the
bullet and had a large batch made.
