| Subject: | Two cooling questions |
It has been the accepted wisdom that if the heat muff is on the pipe,
then air should be flowing through it to keep it from overheating. I
never tested that, but I would just take the heat muff off if I
wasn=99t running air through it. I think this is why all heat
selector valves are two way rather than just on-off.
I would just leave the cooler as isyour vernatherm should keep
the oil from being too cold, you can go for drag reduction later.

Subject: RV-List: Two cooling questions
The airworthiness inspection my RV-6A will be next week, so first flight
will be soon after that. I'm wondering about cooling the engine. The 2
main things that steal cooling air form the engine are the oil cooler
and the take-off for the cabin heat.
1- I certainly don't need cabin heat in Arizona in June. If I block off
the opening in the baffles that is plumbed to the heat muff, no air will
circulate thru the heat muff. Is that OK? Will that stretch of exhaust
pipe get too hot? Is that what most folks do in the summer?
2- I did the oil cooler installation on the baffles behind cylinder #4.
I used the Stewart Warner 7 row oil cooler, so I expect it to be pretty
effective; that is, I doubt it needs the full opening that it has. Will
I do better to block off, say, 1/3 of that to start with, or should I
leave it wide open and just see what happens on the first flight?

I've been using retreads for a lot of years with zero problems. The
retreads seem to last a lot longer than first-run tires. Kinda like the
lifespan of original car tires Vs. replacements Vs. retreads. The
Monster retreads will last a lot longer, but for the recreational pilot
.... well, they'll dry-rot before you get to use up all the tread ....
and they're heavy.

Walt,
While you might not plan on doing any night flying, look a little
farther into the future. When you might want to sell your baby. Most
pilots fly at night, any airplane not equipped with nav/landing/strobe
lights would place it at the bottom of a buyers list.

Configuration reminder:

SamJames cowl/plenum
AeroSportPower built XP IO360B1F6
9.2:1 pistons
AFP injection (Flow balanced to .1gph per AFP instructions)
LASAR ignition (MAP monitor on #4, CHT monitor on #3)
Vetterman Dual crossover exhaust with heater/mufflers
MT three blade MTV12B183-59 propellor
During the first few minutes of operation (essentially through climb-out and throttle-back),
my number one cylinder indicates a higher CHT and EGT.
Neither the CHT or EGT raise to a dangerous level and both return to normal upon
establishing cruise settings.
My number one cylinder also has an injector restrictor that is 5% larger than the
other three in order to balance fuel flow for leaning purposes.
This has occurred seven out of the last eight flights. The missing one is kinda
in the middle.
Data capture is through an AFS3400EM at 1 second intervals. I have data and graphs
if someone wants to look-see.
I am wondering if I might have something in the fuel injection distribution spider
that is partially blocking one line below a certain flow rate.
Any other thoughts,

Matt,
After my original el cheapo tires wore out in about 70 hours, I tried Goodyear
Flight Custom III's (from Desser Tire) and got about 465 hours on the first set.
I make lots of short flights so probably average two or tree landings per hour,
all on pavement ( and very few of them smooth). I'm on the second set now
and I really like 'em (except for the price!)

As a contrary viewpoint, build the plane you want, not what you think
someone else might want. I don't fly at night or in bad weather, so I'm
going no lights, no gyros. Save a few pounds and few hundred dollars.
I'm not building to sell, I'm building this plane for me.

Which ever tire you buy, do not under any circumstances get the Dresser bra
nd no-leak inner tube. Spend the few bucks more to get a name brand. I had
two-flat tires on landings that-were the result of- the very-low-
quality-of-the tubes.--The first-flat (right side)-was due to "
checking" or rotting of the side wall of the tube-and the 2nd (left side)
-was due to a seam letting go. The second tube also exhibited checking /
rotting.- I sent the second tube back to Dresser and-let them know I wa
s not happy with the quality of their tubes. I asked them for 2 new tubes a
nd tires and to pay for the repair of the wheel pants. They credited my car
d for the cost of the tubes only. =0A=0ABackground;- I bought 2-tires a
nd Dresser no-leak-tubes and installed them at the same time during the D
ec 07 annual.- The first flat occured- late 09 and the second about a m
onth ago. Between the Dec 07 annual and now I dont think there has been mor
e than 30 landings on the tires.-7WT is hangared. --=0A=0AReuven-

Hmm, I have been flying my Mooney on the same Desser leakguard tubes for
over 3 years. Yes, I had one for nosewheel that leaked as much or more
as conventional tube, but that stopped when I replaced that one tube.
The mains have been fine from day one. I operate in Aridzona, which is
about as hard on tires and tubes as you can get, with runway temps
approaching 150.

| Subject: | Using flaps for takeoff |
I just had a conversation with a gentlemen from our airpark who said during the
last flyin all the RV-s took off with some flaps. I had been told previously
the flaps in the RV were drag flaps only and did no real good for lift. I also
did my transition training a few years ago with Mike Seager and he did not
have me using any flaps for take off. Since I have not tried it (yet) I was wondering
if some of you are using flaps for takeoff and if you can tell any real
difference. Would love to hear your thoughts.

I only use flaps on takeoff when I have someone in the back seat. I'm
certain the tail comes up more easily with a little flap.
As to whether it improves runway performance in terms of shortening the
required field length or not...are you kidding? It would have to be a
REALLY short field before my -8 started having to worry about it.

Way back before the turn of the century when I got my free ride in the
factory RV-8a here at Arlington, WA with Bill Benedict, then general manager
of Van's, I remember him commenting that although it wasn't necessarily
recommended procedure, he "did it like a Cessna" and put in a little bit of
flaps on takeoff. I don't recall his reason, if he gave me one.

I'm not sure with RVs, but....wouldn't flaps (ie 10 degrees) be used for
soft field takeoffs and no flaps for short field takeoffs (ie clearing
trees at the end of a short field)? That's how it works with Cessnas
and I assume Pipers and Mooneys as well. That's the way I was taught
(in our Cessna 140), but maybe that's old school thinking ;)

Well, I can tell you that in a Cessna 170B and up, flaps shorten takeoff
roll and clearing an obstacle until DA is more than 4500 ft. The old
ones used 20 degrees until the 172 added a notch for 10 degrees and that
was what was used. The Mooney uses 15 degrees of flaps for all takeoffs
unless crosswind is too strong to handle with flaps, regardless of DA.

I can see how 10 degrees might lessen the takeoff roll due to being able
to lift off at a slightly lower airspeed. Can anyone explain why the
obstacle clearance would be better with flaps down? There is more drag,
so wouldn't rate of climb be slightly less? I suppose if you climb at
just above stall speed, your ground speed would be lower, thus taking
longer to get to that tree line? So, why do instructors teach flaps for
soft field and no flaps for short field?
What does the POH in the 170B say about soft and short field ops?

The reason is the same for most airplanes, Vans included. More lift.
To Tim=92s question that included the statement =93all the RV-s took off wi
th
some flaps=94
Well it=92s hard to get all pilots to do anything the same let alone us
non-conformist =93don=92t tell me what to do=94 Experimental pilots. I have
never
heard of a flap that was =93drag only=94 seems near pointless, might as wel
l
avoid the weight & complexity of flaps that do not produce lift (and drag).
The entire RV product line is extremely versatile and can take off with no
flaps in most environments. The RV-10 is the only Vans design (I don=92t kn
ow
about the RV-12) with a 3 degree flap take off setting to improve hard
surface take off performance. That being said adding some flap to all RV
models should shorten take off roll. How much is needed or ideal depends on
the plane, weight configuration, runway surface etc... Most important is
that you as a pilot remember the flaps are deployed and do not exceed Vfe.
So Tim give 10 degrees a test to see how it makes a difference on your ship
.
Then try a little more and a little less.
For me flying my RV-4 & RV-6A both with 180 Hp I never used flaps on takeof
f
unless I was practicing or had concerns of clearing obstacles. In those
cases I usually kept my hand on the throttle and finger on the flap up
toggle as a reminder to retract flaps when able.
Good luck,
Robin

I can't speak for Cessnas, since I have very little time in them.
Every other airplane I have flown is designed to get off as soon as it
can, that is at the lowest speed with which you can be assured of
flying under good control. I have not flown any airplane which takes
off without using flaps, if it has them.
The RV-6 I do know about and have quite a few take offs. Here is my
take:
the first 10 degrees (1/4) flap is mostly a lift gain and very little
drag added at low speed. You also get a new MAC line which gives you
a higher angle of attack at a given deck angle. If you go further
than 10, you start getting mostly drag and little or no add to the
lift. As I see it, your choice is to use 10 flaps and get off a
little sooner, or use no flaps and roll a little longer. I believe
the plane will accelerate better once the wheels get air under them,
so the obstacle clearance will be better, too. Lastly, the deck angle
is lower with the ten flaps and you can see better for that point in
the take off where you are just lifting off. Retracting the flaps is
the first thing I do after take off. before boost pump, RPM, or
throttle.
Consequently, I always use 10 flap for take off, except in a severe
cross wind (above 25K). In that case I am going to "pull it off" for
take off with a raid rotation. If you use any flap in that condition
it may crow hop toward the down wind side of the runway. Very
difficult to control..
A lot of RV guys don't use flap for take off and I don't think it is a
big deal. I do recommend every one try it, and try some stalls at 10
also. I think you will find the plane has a much more solid feel at
low airspeeds with the flap down a little. My personal observation is
that those folks who don't use flaps are operating at a lot higher
airspeed than I am. That's ok too. If you are going to not lift off
until you have 70 knots then why would you use flaps? Same applies
for landing.
I will offer that my tires last longer than most. Personally I
believe this to be because I try to touch down at 45K, and take off at
the same speed.
I don't think there is a good solution for everyone. For those who
don't fly much it makes sense (to me) to use higher speeds and longer
take off rolls. That is not for me, however.
For most of us, the RV normally accelerates so fast that this one or
two knot difference in stall/lift off speed is hard to even notice any
way. You will really notice it at high altitude hot day max gross
weight.
I hope this "one man's opinion" helps. Everyone sees it a little
different.

I do not use flaps for takeoff. I was not able to to measure any difference
in takeoff with no flaps=2C 10 flaps=2C and 20 flaps. This was over 12.5
years ago.
I will use 10 flaps on SOFT grass fields. I do not think it reduces ground
roll on grass but I feel that it may reduce some of the weight on the mains
.
If anyone has some data that shows a difference=2C please share it. Also l
et us know what model RV=2C HP=2C and prop.

Hi all:
I'll be traveling to Cedar Rapids Iowa on the 3rd of July and plan to be
there until the 12th. I'd like to fly my airplane to the Cedar Rapids
Airport (KCID) because it's closest to where I want to be. I understand the
main runway is under construction and it's only a moderately friendly
airport (TSA security issues). I'll deal with that if I can find a place to
keep my airplane there. Anyone have some recommendations as to what FBO to
use there? Do they have some hangar space I can rent for 8-10 days while
I'm there? Or would it be best to go to one of the smaller, uncontrolled
outlying airports? If so which one? Any help would be greatly appreciated.
Thanks.

As others have said, they definitely add lift.
I came to a purchased -4 after ~200 hrs in a Swift, with flap settings
of full or none (never used for T/O). Never thought to try T/O flaps
through 7 years of flying that 1st -4, and through about 3 or 4 years of
flying the 2nd one. Then one day at a neighboring strip's flyin, I
forgot to retract them (full flaps) on T/O. I was off much quicker than
expected, and seemingly near pattern altitude before the end of the
strip. Felt like departing into a 20kt headwind. Since then I've played
with them several times, but just for fun. Even with only 160 hp, it
would take a really short strip to make flaps seem necessary. On the
obstacles issue, I'm no authority but I'd assume that the reason
flaps-down gets you over obstacles better is that you have an improved
climb *angle*.
Anyway, I can't see any reason to avoid using them on T/O, except the
surprise you might get if you aren't prepared to be off the ground so
quickly. Try it; you might like it. :-)

Hi Gary,
Living 6 miles form Van and watching him fly frequently, I guess the
best evidence for using flaps is to watch him takeoff, almost always uses
flaps and consistently shorter takeoff roll then most others.

POH for a C170B last produced in 1956? Surely you jest. It had a one
page 5X8" two sided FAA approved flight manual. You climb at Vx, which
for most planes is flaps and gear down. Best angle of climb, which is
what you need when obstacle is near. The FAA short field definition
rarely meets real world...paved runway, just short distance to obstacle.
Most real world short fields are also either soft or rough fields and
flaps are needed. Just my experience in 700 hours of flying 170B in
Alaska. Instructors teach what the FAA dictates to pass the test. I do
happen to have a C177B POH handy, which calls for 10 degrees for normal
takeoff and 15 degrees for max performance takeoff:

Hi Dean - my plane is at KCID. Runway 9/27 is closed but the taxiway (now
8/26) is open and plenty log. 13/31 is also open, for now. It will close,
I think at the end of July. The runway thing is no problem, just no
taxiways.
PS Air is the more friendly FBO for small airplanes. I'd call them and ask
about hangar space. They are good people.
Good luck,
dave

Intake leaks are easy to find. clean out your shop vac real good and
set it up to blow instead of suck.
Stick the hose in the intake and seal with shop rags. Spray soapy water
all over the intake system and look for bubbles. Two most common leaks
are the intake coupling hoses and the are where the intake comes out of
the oil pan ..... that's a swaged part, and to fix correctly requires a
swaging tool. I've seen them fixed with JB Weld to silicone sealer though.

The only flat tires I've had in 4,500 hours of flying were with Michelin
