Good luck. Around here, the service hasn't been that good. I bought from
them when I first started building Scooter way back in 1992 and quit buying
from them, after a bit. Then, I started buying from them again around 1996
after they assured me they had changed. Yeah, sure. I stopped again. I've
found their service, pricing, shipping practices, etc. not up to par with
the other companies I've bought from. Today, I use Wicks for most of my day
to day stuff. I only use Aircraft Spruce as a last resort when I can't find
an item somewhere else. Maybe the new location in Georgia will help. I got
better service out of those folks than the ones out west. I must admit that
I do like their catalog. I use it for ideas before buying from somebody
else.

--> RV-List message posted by: "Donald Mei" <don_mei@hotmail.com>
Just a couple of thoughts not strung together with any particular coherence:
One of the benefits of a Ryton sump and runners goes beyond the weight
issue. Plastic does not conduct heat like metal. The Ryton runners will
result in a cooler charge than any metal integral sump/manifold. Although
certainly not as cold as an external manifold.
Another exapmle of Magnesium in aircraft engine is the LOM inline engine
thats somewhat popular with homebuilders. The crank case is made of
magnesium.
Someone mentioned titanium. Only problem with that is it is heavier than
aluminum.
(Titanium 40% lighter than steel and 60% lighter than aluminum)
titanium is used to replace steel
magnesium is used to replace aluminum
Aluminum, like magnesium will burn. Its just harder to get it to start. In
practice its not an issue, but aluminum will burn. The space shuttle solid
rocket boosters burn aluminum.

I have to agree with Jim. I've had horrible service from ACS. I'll pay a
premium somewhere else just to avoid them. I'd much rather give my business
to the small shops and individuals that seek our business, rather than
expect it - Abby, Stein, both Bills, Paul, Duck, B&C... it's a long list.

Scott,
I'm sorry but someone misquoted you. In the Operating Limitations for your
aircraft one of the first paragraphs states that the aircraft will be
operated in accordance with ALL the operating rules of FAR 91. FAR 91
includes the subpart on maintenance. One of those paragraphs in that
subpart states that all discrepancies will be corrected between inspections
and a log entry will be made. Another one says that all logbook entries
will be in accordance with FAR 43. The parts of 43 that cover logbook
entries is FAR 43.9 and 43.11.
I'm sory that I can't get more specific at this time but our office is in
the middle of moving and my regs book is packed away. If anyone wants more
specifics let me know and I will be able to do so next week.

I would at least install one of the old "style" ELTs for now. They aren't
that expensive and have a better chance of helping you out if something does
happen than if nothing was installed.

For those of you that like engine puzzles give me some ideas. Engine is a
Lyc IO-320 in an RV-9A.
Here's the symptoms and some findings.
During flight #4 cylinder starts showing a high EGT (about 1470) and a low
CHT (about 320). All other cylinders show around 1360 EGT and 360 CHTs.
All other engine parameters stay normal for temps and pressures. There are
two other symptoms. The fuel pressure starts to drop off but comes right
back up once the electric pump is turned on. This has no effect on the
cylinder temps though. Once the high temp was noticed mixture was enriched
and all temps on all cylinders went down but the #4 EGT slowly started
creeping back up. Push the mixture in more and temps go down across the
board again but then the #4 EGT starts creeping back up. During the
approach to land there are lots of exhaust popping. (lots of fuel in
exhaust).
After landing, compression checks on all cylinders showed 76-78 over 80. A
visual inspection of the exhaust values showed nothing wrong. A wobble
check of the #4 exhaust valve indicated everything was ok. The fuel
injector was pulled and found to be in good condition. The top taken off
the flow divider and everything was clean. both the fuel filter and the
gascolator screen were clean. The only thing found so far was the fuel line
coming from the servo to the flow divider had slipped off the heat shield
and was sitting directly on the exhaust pipe. The fire sleeve was charred
but the fuel line (teflon braided) showed no damage and was clear.
I have been working with these engines for some time but this is the first
time I have come across this one. Anyone have any ideas. I am beginning to
wonder if just re-routing the fuel line might fix everything. Maybe a
bubble got into the #4 injector line causing the #4 cylinder to go lean??
By the way, this is a Bart engine. He has been contacted and we are going
through different things there also but I wanted to get some more ideas.
Thanks,
Mike Robertson

Bad spark plug on #4 cylinder? Plugs can go bad without fouling. They
should be pressure tested at every annual. Try running on each mag next
time. If it's a bad plug the cylinder will go cold when that mag is
selected.

Any way you can swap the thermocouples? Example - swap no 2 CHT & EGT leads
with no 4. Just to be sure it's not instrumentation... then you can move
on to engine troubleshooting if necessary.

remove the fuel injector from the cyl ams swap it with one from another cyl.
it it is the problem, the problem will follow it. they have to be cleaned
sometimes. the popping sound is a sign of too lean mixture. could be from
retarding throttle too fast too. tom kimsey

Anyone have an opinion on the G307 switch from Ray Allen? I'm not sure I've seen
one before but I like the fact that the "hat" trim switch is rated at 15 amps
and can take the load of a direct hookup to their servos. But at 6.5 inches
tall it seems to be on the long size.
Also, I ordered Van's flap positioning system. If you have one, what kind of switch
do I need on the Ray Allen grip. It sounds to me like a momentary on both
up and down and middle off.

Popping is from the Vetterman exhaust and a rich idle mixture will make it
worse (ask me how I know) but it will always pop with injection and
Vetterman exhaust.

There is a lot of difference between Mach 25 and Mach 3.5. Also, a lot of
difference between going straight up and down and going into orbit and then
going through re-entry. My hat's off to Rutan and his team. But it's
apples and oranges. Why should NASA officials be cringing? Hybrid solid
propulsion has been around for years. The Shuttle's solid rocket motors use
rubber and aluminum for propellant. Rutan's rocket motor was based on a

It took NASA many, many more man years to achieve similar results with
the X-15 using an existing bomber for the mother ship. SS1 has a
pressurized cockpit. I don't think the X-15 did. Nitrous Oxide and tire
rubber! Amazing! NASA officials must be cringing. Just wait for press

If the possibility of an exhaust valve problem has
been eliminated (and it sounds like it has), this is
most definitely an ignition problem. One plug
dropping out will reduce CHT's and increase EGT's.
Could be a plug or a bad wire.
I don't think I would bother swapping injectors, and
since you are seeing temperature changes on both EGT
and CHT, I think that would eliminate the possibility
of a TC problem (TC's virtually never give a slightly
erroneous reading. Either they work or they don't).
Also, it's quite possible for a plug to work OK during
a normal run up mag check, but drop out at climb and
high cruise power settings.

One of the things I found that contributed most to difficult pin insertion
was that the eyes were not lining up between the two hinge halves- If the pins
slip easily through each half by themselves, carefully look for anything
BETWEEN the eyes that would prevent the eyes from aligning- I had to dig a lot
of
little flidgits of epoxy/flox from these areas to get proper alignment- Since my
cowl pins go in through the firewall, having to wrestle with them would be
rather uncomfortable and drill motors don't fit well under there. A light coat
of wax on the pins helps quite a bit too...

That's for sure. I'm not sure the current craft will scale
to orbital velocities, or the re-entry method, which is quite
novel. I think a lot of people would be curious to know
what NASA people think of this effort. I'm not sure I
understand Rutan's public animosity toward NASA - which he
pronounces "naysay" - unless it is an attempt to motivate
his team. It's good to have a competitor to keep the
adrenaline flowing.

| Subject: | ray allen grip & Van's prepositioned flap switch |
--> RV-List message posted by: "Terry Watson" <terry@tcwatson.com>
I have and am installing the flap positioning system, and you are right
about the switch - up is momentary on, middle is off, and down is momentary
on. There are no provisions for two flap switches, such as front and back
seat, so a switch on two sticks probably would require using relays. I have
figured out a way of adding a switch on the panel that sends control of the
flaps to either the pilot or backseater, or disables them, but it
complicates the system and the manufacturer doesn't recommend it. I haven't
decided yet whether to do it or not.
Also, with the flap positioning system, a part of it will come through the
rear left armrest as the flaps are raised and could easily snag on someones
coat or whatever, so it needs to be covered. I made a satisfactory one out
of some scrap Plexiglas, but aluminum might be better.
It helps if you would sign your name so I knew who I was talking to.

Also, I ordered Van's flap positioning system. If you have one, what kind
of switch do I need on the Ray Allen grip. It sounds to me like a momentary
on both up and down and middle off.

To sum up what Rutan thinks of NASA. He said that it would cost NASA more,
than the 20 mil spent on Space Ship One, just to do the feasibility study,
to see if what Space Ship One did, was possible.

As for scaling the current craft for orbital velocities, I say probably not.
As for surviving re-entry in a fiberglass craft, I say no chance whatsoever.
That being said, I don't know that orbital flights are the goal. It's not
fair to draw comparisons between NASA and Scaled Composites. To tear Rutan's
crew down because they can't go into orbit makes as much sense as saying an
RV sucks 'cuz it can't go underwater. Spaceship One did ITS thing very well
and for that they deserve all the bragging rights.

If the switches are uperating as you describe, just hook up a

OK, let's compare results on NASA's (in cooperation with Continental) recip engine
results. They spent $10,000,000 + of our money and an unknown amount of
Continental's cash and could not even fly a single engine at Oshkosh 2000 which
is all the contract required. (we didn't get our money back either).
Burt & Co. built an entire space program, built a new aircraft and spacecraft on
$20,000,000.
A hell of a lot better bang for the buck than NASA got.

I believe that the B&C starters have bendix-type shafts which can stay
engaged after a failed start. The Sky-Tec doesn't. I have Sky-Tecs
(yep, plural!) Drop Les Staples an email at lstaples@itexas.net about
the Sky-Tec .... don't have a contact for B&C

Rick,
I'm working on an RV-4 as well. Wings and empennage are complete and will begin
the fuse this month. Have a Lycon 0320-D1A and a Whirlwind 3 blade prop that
will go on.
I'm moving to Fallbrook in San Diego County and would like to get connected with
other RV'ers in the So Cal / San Diego area.
I'd appreciate hearing from any of you fellows in the area, especially if you know
where I can get a hanger.

When you get to the area look me up. Lots of RV's at SEE.
The Fallbrook airport is on a hill, narrow, and short so its fun to land
on. I think they also have hangers available there. I would call Fallbrook
ASAP to check on the hanger list. It also looks like new hangers are
available for sale/rent. See the web site:

Because there was an acquaintance on the panel, I watched a televised NASA
discussion on expedition risk management, last week. I was struck by how
many times the name Burt Rutan came up. There did not seem to be any
negativity toward him, just a wonder at what he had accomplished. Some NASA
participants did offer reasons why they felt NASA does not get as much "bang
for the buck."
One reason given was that NASA does not have a narrow and well understood
focus anymore, in contrast to the moon race days, when much was
accomplished.
Another person commented on how in programs like Burt's and some of the
panel participant's, the people doing the planning and designing and
building are also, often, the participants. Wonderfully focuses ones
efforts.
I think they really were trying to take some of the lessons Burt and company
are offering.

Mike, you've seen a lot of good suggestions, several of which I was also
going to suggest. The three that make sense to me are...
1) Bad spark plug -- swap with another cylinder, and/or try running on one
mag at a time and watch temps. Also, don't forget the spark plug wire, might
have a break which changes resistance with temperature.
2) Uneven injector -- swap with another cylinder and/or measure flow off the
engine.
3) Exhaust valve -- least likely, but there could still be some gasses
getting by the exhaust valve, in spite of the tests you've already done, for
some reason which would explain the symptoms.
Now *please* let us all know what ends up being the cause so we can all
learn something!

Hi All,
I'll have my Kettle Korn business operational during the Copperstate Fly in this
weekend. I'll be in the food area by the large vendor tent. I'd like to offer
a $1 off the large or medium bag of popcorn to RV owners/builders. I'll also
have drinks for sale. Most importantly come by and talk RV's. Next year I'll
be flying there!!!
The only thing holding me back is the purchase of my last avionics items. Please

An induction leak will cause that cylinder to run lean.
I had intermittent slightly rough running in flight (no multiprobe egts
available on this one) on an O-320. Seemed to show up after 15 minutes
to an hour of flying. I found an induction tube loose where it enters
the sump. Had to loosen the tube's cylinder attach nuts to find it.

I bet this difference between Mach 25 and Mach 3.5 and the up/ down thing is
gonna be a big surprise to the Rutan team.
NASA is a government agency- it's top heavy with management, it's top heavy
with meetings and the people that can get things done are largely ignored.
NASA couldn't win the XPrize.
Rutan designed, built a specific vehicle to do the task. It flew on Friday,
they changed the engine on Saturday, they cleaned the windshield and put air
in the tires on Sunday and took the money on Monday. 170,000. members of the
EAA KNEW they could do it.
If the Rutan team ever decides to build a vehicle to do Mach 25 then NASA,
Lockheed , Boeing and the others should pay attention !

--> RV-List message posted by: "Terry Watson" <terry@tcwatson.com>
Thanks, Jim. But thinking about what you said and reviewing an e-mail from
Bryan Milani at Show Planes, I realize I posted some wrong information in my
original message.
So, to Rv8er@aol.com, I was wrong about the switch. The up (retract)
position is NOT momentary. According to the instructions, it stays in the
up position until you put it back in the center position. I have it in
front of me, and it is momentary in the down position, but it stays in
either the up or middle position.
Here's most of the e-mail from Bryan at Show Planes, apparently the supplier
to Van's:
"For a
couple of reasons I do not recommend installing two switches. If one switch
got left in the retract position the signal to the control box would not
allow the other switch to operate. There would have to be a command switch
that controlled which switch was operating, by doing this you now have two
switches to operate the flaps thus complicating this critical phase of
flight. For these reasons Show Planes can only recommend the installation
per the supplied instructions."
Sorry about the misinformation.

Terry,
If the switches are uperating as you describe, just hook up a
second switch in parallel. As long as you both don't try to use them at
the same time, things will be fine.

Splitting the prize with the employees is in fact "way cool"!
Being the world's 5th richest (??) with a net worth of over $20 Billion (I
think) ... nope, don't think he did it for the prize money "net loss" of
$10M for the moment. :-) Probably spent about one week's worth of annual
*INTEREST* earned. Gotta be nice. :-)
[These numbers are approximate ... I MAY be wrong]
BUT!!!! What is great though is that he did in fact (quietly) decide to
pick up the tab to help "make it happen".

The above understates the difference. The energy involved per pound of
vehicle that gets to orbit is about 50 TIMES as much as compared to Mach
3.5. That being said, Burt Rutan has said more than once that he
doesn't think orbital is that far off. Never underestimate his creative
mind to find some slick way to deal with those absurd energies.
BTW, when the 200,000 lb space shuttle is in orbit, it has kinetic and
potential energy equivalent to lifting a 90,000 ton aircraft carrier
straight up a little more than 2 miles! Think about that.

I seem to remember a physics teacher saying that ANYTHING will burn. Think
that plastic sump won't burn! I know steel will burn. Ask anyone who has cut
steel with a torch. Just get the temperature up and add oxygen. But we're
getting off topic here! Some things burn better than others!

Subject: RV-List: camera in the tail
--> RV-List message posted by: "David Burton" <dburton@nwlink.com>
I thought I had saved a link to the builder who mounted a video camera chip
and lens in the tail of his RV. If anyone can post a link to the website
I'd greatly appreciate it. Specifically I'm looking for his (or a) source
of c-mount lenses.
Thanks!

If the old std 121.5 and 243 hz are to be obsolete by 2009, when can on
begin using the new 406 version? If flying with a 406 is possible next
year, I could be interested in "pointer".

The new ELT's at the moment are quite pricey. I looked at stocking
them,
but the only decently priced one out there that is (COSPAS/SARSAT)
compliant
for 2009+ is high $$ compared to the current $180.00 ACK & AK's.
Anyway, if anyone is interested, pointer makes one in the
$400.00-$500.00
range. If you're interested in one, contact me off list and we'll get
you
setup.
Cheers,
Stein Bruch
