Which port should be pressure to the oil cooler and which one return on
an O-320? The one I think is pressure is to the right of center on the

right?

| Subject: | looking for a prop |
I need to replace the prop on my RV4. I have been flying a constant
speed up
to now, but it has become uneconomic
to maintain/repair. I am going to try lighter/simpler for a change, so
I=92m
looking for a wood prop suitable for a 160hp O-320.
Any recommendations based on actual operational experience would be
appreciated.
Also, if you know of one currently for sale please let me know.
Thanks,

I had an Aymar Demuth on my O-360 RV-6A. I converted to a three blade
Catto prop
and only picked up about 3 mph so either is an option.

I concur, I fly an Aymar Demuth, he custom builds them to your plane
and type of flying. My cruise is very close to Vne. Cruise is much
faster than what Van publishes, and climb is still better than Van's specs.
BTW, why is the constant speed uneconomical? I have never owned one.

Great post, LimaTango!
I have two quotes posted on my cork board at work:

skywards, for there you have been and there you will long to return."

| Subject: | Flying without gear leg fairings |
Hi all,
I have been flying my RV-6 without wheel pants or leg fairings since October
when it first took to the air. I had my wheel pants fitted but not the leg
fairings. I am wondering if anyone sees a reason why I can't fly with the
wheel pants on, and the leg fairings off. At least till I find another day
I can spend working on it to fit the leg fairings. Too much flying to do
and not enough days to work on it.

| Subject: | Re: CHT's and EGT's Spreads? |
I thinking about these very questions myself and went to the Skyranch
Eng Manual for some guidance.
To summarise for cruise:
Normal EGT range: 1200-1600 F no mention I have found for maximum
Oil Temp: 160-245 F with minimum continuous 165
CHT: minimum 150 F, normal 350-400 F (435 for turbocharged)
The Skyranch recommendation is to impose a secondary redline on CHTs of
400 F for normally aspirated engines, leaning should result in CHTs
below this.
The issue with uneven temperatures is possible uneven cooling of the
cylinders leading to cracking. The proposition is that large variations
between cylinders implies uneven airflow around the cylinders. The
recommendation is to balance the temps with baffling/deflectors.
This makes sense to me and it is the reason I am fitting individual
cylinder CHT monitoring.

There is also a secondary pressure out port, at least on the 320-E2D I have
that came out of a Cardinal. It is right above the oil screen housing next
to the breather port. I'm using that one because it already had the hose
fittings, but mainly because I couldn't get the #$%&*@# plug out of the
center hole.

Tim,
I flew my 6A for several hours with just the wheel pants. No leg
fairings and no lower intersection fairings.

>>>
Sure- your carbon signature will be higher- put on the leg fairings and enjoy
the efficiency improvement! Better yet, try a leg fairing on one side and a
pant on the other. You never know, you might like it like that- somewhere on
your plane should be a big sign that says "EXPERIMENTAL", so whatever floats
yer boat.

(we now return you to your regularly scheduled ?: Can't think of any
particular reason not to fly with your pants on and your leg thingies off, unless
it
has something to do with the mile-high club or somethin'...)
