REFLECTOR: Reflector Digest, Vol 49, Issue 64 - Oshkosh Dorms

Sat Jun 28 15:00:34 CDT 2008

If you are still looking for a dorm room, I have a friend with a reserved
room from Tuesday thru Saturday who just found out he can't make it and is
looking to sell it. If anyone wants it, just email me at anriley at comcast.net
and I'll put you in touch.

The concord rg is a great battery.

The Hawker (Enersys) Odyssey is the same technology at half the price.  
I think Hawker's been making them longer than Concord.

If it is sunny, mid 90's or more in the day. Make sure you have good
hats and suntan lotion. Nighttime it doesn't really get cool, just
comfortable.

Bring rain gear!!

I'm still trying to talk my spouse into gthe airventure trip this year.

Se is very concerned that tents and dorms don't have airconditioning.

What can we expect for daytime highs / nighttime lows for the week?

Speaking of dorms...  all that are left are Ripon and Marian colleges.

Any one know of a reason to prefrence one over the other?

(snip): I noted early on that it took an unnecessarily high pressure to
release the lock because of the lever arm of the release spring.  I moved
the spring about 4-5" closer to the pivot, and alleviated that issue.

Al...How much free tension do you have on the cable when the gear is down
and locked...? Maybe there is too much free play on the lock side and the
over center lock is not releasing before the gear starts up....

Steve;

The cable is just 'snug' when the gear is down.  Reducing the tension force
in the cable required to unlock the latch insures its release in a timely
manner - if it makes any difference in that regard. I had calculated the
cable tension required to release the latch, and it was in the hundreds of
pounds (don't remember the number).  More than that required to lift the
gear - seemed clearly excessive to me.  This hasn't shown up as a problem in
anyones plane that I know of; so it was just something I did to reduce the
stresses on the system in getting the gear travel started.

I have no idea of your cooler configuration; but you'd want the exit at the
top so air doesn't get trapped in the cooler.  Given that - it would matter
which connection on the engine is the outlet.

Is there an inlet and an outlet on my oil cooler? I don't see any markings,
and I don't see why it should make any difference. Similarly, on my Lycoming
engine there are two ports for the oil cooler. The guy that assembled my
engine told me which one was the inlet and which one was the outlet, but I
forget now. Does it matter?
