I have a SkyTec and Lightspeed and I ended up changing to a
wound field SkyTec and it all works fine. My opinion only but I would
use a wound field and not permanent magnet starter with the electronic
ignition. I guess in some cases the PM starter with its high inrush
current pulls the voltage down below the compliance voltage for the
electronic ignition. All works fine now.

I believe Sky-Tec is/was worried about kickbacks being caused by
electronic
ignition systems at lower voltages. i.e. (and I'm pushing my knowledge
envelope here, so correct me if I'm wrong) the possibility exists that
while
cranking, the voltage to the EI would drop, and the EI might go nuts and
spark at an inopportune time, causing a kickback.
> Anybody have a Skytec and a Lightspeed who can attest to its
performance?
I have both. Sky-Tec LS flyweight starter and a Lightspeed Plasma II.
The
only issue I had was with the Sky-Tec solenoid which died around 110
hours.
Not related to the EI. I've been running the same starter since with no
probs. I learned to carry a spare solenoid (thanks Birdstrike & Rosie)
in
my tool kit just in case.
I'm not saying my experience counts for anything, but you asked. ;-)

Mike,
Opinions are never in short supply and that goes triple for the good folks in our
aviation community, so here's mine. If it were my airplane, I would not hesitate
to drill the bad rivet out, clean up the hole to the next nominal diameter,
in this case with a #20 drill bit, (better yet, a #22 drill then final reamed
with a .160 or .161 reamer), then install an AD-5 rivet. The defect you
seem to be describing ..... 1/3 the thickness of the spar reinforcment sounds
to me like fertile ground for increasing the chances of a stress fracture to develop.
Personally, I would not want to dwell on nagging doubts about a known
defect I chose to ignore while bouncing around in turbulent air. One final word........there
are tech counselors and there are tech counselors. My first
tech counselor visit was with a wood and fabric guy who knew as much about sheet
metal work as I do about flying wires. The glowing form he submitted to the
EAA was all well and good but in the end, I know in
my gut
that the session was little more than a paperwork dog and pony show. Find someone
who is really experienced in sheet metal work and not just anyone who simply
qualifies as a tech counselor.
Rick Galati RV-6A "Darla"
The one I am most worried about is a rivet that holds the front inner rib to
the from spar reinforcement. My first rivet got bent going in. I drilled
it out from the wrong side (shop head) and got a little way into the spar
reinforcement bar. I re-riveted it with the same -4 rivet. You can see a small
defect from my over drilling. I was considering the following options:
1. Leave it--put in some primer around it.
2. Drill it out and go with a larger size rivet
3. Drill it out and put in a small 3/16 bolt.
Since the hole only goes about 1/3 of the thickness of the spar
reinforcement, I thought it might be okay to leave. I will see what the tech
counselor
thinks. Opinions here?

Bob,
I have a 13 bay classic mounted on the firewall, with a 3" SCAT tube from
#4 cylinder.
on my RV-6A, O-320-D1A ... I'm finding that it's not getting enough air to
sufficiently
cool the oil on hot days (OAT > 95*F). Oil temps go up to 230*F under those
conditions.
When I called the Niagara people about changing coolers, I was told that I
should have
at least a 4" SCAT tube, preferably a 6". I'm thinking that taking that much
air from the
top of the engine would introduce engine cooling issues. I'm now considering
a NACA
vent off the left lower cowl.....

I toyed with the idea of taking the cooling air from a NACA vent on

the cowl inlet for cylinder cooling instead of bleeding off air behind

Good advice!
I found it interesting that in my kit NONE of the rivets that had been
installed by Van's and most of the rivets installed by Phlogiston ( the
company that makes Van's anodized wing spars) meet the ideal definition for
rivet installation...
I shoot (pun intended) to meet the ideal with every rivet, but looking at
what was delivered by the factory gave me the confidence that deviation from
the ideal was acceptable.

Dear Fred,
You run a 13-row cooler for a O-320 and it is still running to hot? A 7-row cooler
should do the trick when fed with adequate air flow. I agree that a 4" scat
would help, but 6" seems overkill (...where would you even put it in the tight
space?).
Konrad
BTW: A friends Cherokee runs a 180hp with a 7-row cooler & 4" duct of the rear
baffle with no problems.

Michael,
I borrowed a flycutter and worked it in a drill press. [CAUTION] Make
sure that you have a very low speed drill press and secure the spar
doubler very well! [/CAUTION] See results here:
http://rv8a.parashak.net/comments.php?id=P26_0_1_0_C
A hole cutter would be better but, the holes are different radii are
different and non-standard. I just went slow and steady.

Hi David,
I've lived in the Ahwatukee area of south PHX for about 5 years and have a 6A in
my garage which just had the engine hung. Here's what I know about the local
aviation community and city.
There are 4-5 main airports to house your airplane: Scottsdale, Falcon Field (Mesa), Deer Valley, or Chandler. Others are further East like Goodyear. PHX International is for the big boys. You will find they all have waiting lists for hangars & tie downs - some for 10 years! Most renters end up sub-leasing from other hangar owners. You should try contacting all of them ASAP to find out how things look. The Scottsdale EAA chapter (#1217) seems to be the most active. Here's the link: http://www.acsinfo.com/eaa/index.htm Deer Valley would rank second, the others seem dead. There are a lot of warbirds at Mesa. As usual there are RV's everywhere. Pretty good group at Deer Valley, and a handful of builders I know at Chandler. Scottsdale has more varied experimentals.
I have a neighbor building a -9A at the same stage of construction as me. We have
a short term lease on a hangar at Chandler to get us to first flight. Due
to hangar shortage we will likely be based at Casa Grande about 30 miles to the
south of PHX. Prices there are also a little better. They have new hangars
under construction, and it is the new home of the EAA Copperstate Fly-in.
There are also a couple airport communities: Pegasus and Stellar that would give you an opportunity to build on them if you prefer. As for real estate - thing have spiked here in the last year. 20-30% increase in housing prices. Most last a day on the market and go for more than asking price. Scottsdale is particularly costly, but a good investment. Know as 'Snotsdale' in some local areas. I choose Ahwatukee due to low crime, great schools, clean community and high social standards. It was also close to my work location in Chandler, and the PHX airport that I fly out of for business and leisure. I found this website to be helpful: http://www.southwestrealestate.com/
Good luck your search and write if you have more questions I can answer.

Vince, give me a break, 1 woman Vs. 15 woman. Wishful thinking to the max, and
I doubt you would know what to do with them. ;- )
One) The current top plane of the Cafe Foundation, CAFE Triaviathon is a RV-4, beating a Mr H's HRII. (http://www.cafefoundation.org/aprs/RV-4.pdf) After all a HRII is still a RV. Your 1 to 15 girl analogy for the RV vs HRII is more like your wife wearing 15 different wigs.
Two) The Rocket, HRII or F-1, are nice, but all its extra attribute (performance
over RV's) is Horse Power. It is just a clip wing, stretched RV-4 with a IO-540.
They handle good because it is a RV. OK, your 1 to 15 girl RV vs HRII analogy
is more like your girlfriend got a boob job, but sorry no 15 girl action
Buddy.
Three) What makes RVs fun is they way the feel and fly. Climb rate and top speed
is part of the picture. Yes, the Rocket is faster and climbs quicker (220 vs.250
mph , 2500 vs 3500 fpm, no denying HP). The Rocket has 14% more performance
than a RV. OK your up to a 3-way with Jennifer Aniston and her girlfriend.
Vince, you are justifiably proud and have a very active imagination; Congratulations
on your Rocket, very nice. Fly safe. Those fast women can burn you. :-)

But what about the Rocket? Well, I still like to fly RVs, but given a

Let me explain: Flying RVs is like spending the night with Jennifer
Aniston. Flying the Rocket is like spending the night with Jennifer
Aniston, Cindy Crawford, Sandra Bullock, and 12 Victoria's Secret
models... and they're fighting over who gets you next.

True the sky-tec takes takes more current to get going which can draw down the
voltage
Kick backs are not Sky-Tecs problem, it is an ignition problem
If you kick back you can break the starter nose casting
Low voltage plays havoc w/ all elect ign, causing them to miss fire and kick back
during start
The LSEII (or LSEIII) should do the best of any EI because it can operate w/ low
voltage
Electoair requires more volts than the LSE and may be more sensitive to low volt
start
My basic Sky-tec, no problems over 600 hours, but with mags
EI on starting, you can use 2nd small battery just to pwr one EI (isolated from
starter)
Using the back up battery for EI pwr & starting will eliminate the problem (if
ignition related)
Sky-tec offers the HT version which has lower current requirements
B&C is nice but cost too much
Most can use the cheaper Sky-tec, the HT version cost more but is a better starter
SKY-TEC, all are nice reliable products
Small battey, large gage wire, good connections (+ and -) to starter, you will
be fine.

Dan is basically right. I just ordered my RV-10 Aerosport IO-540 engine
today and talked to Bart about it. He recommended getting the
HT Sky-Tec starter with my Lightspeed III ignition. I didn't follow
it perfectly, but it basically amounted to the voltage dropping when
you crank the engine. I don't think he said it caused kickbacks, but
maybe just poor starting. Anyway, I'm hoping to use a dual-bus system
and run my lightspeed on the essential bus...separated...during starting
anyway, along with an instrument or two.

Hi:
I'm a Chapter 1217 member. I recommend it. Meets at Scottsdale
Terminal 700 pm third Thursday each month. Next meeting is special May
Day (05.01) at a members hangar... North side of Deer Valley field.
Come on down if you can. A big majority of our member are based at Deer
Valley (cheaper hangar rental rates and shorter waiting list .. ours was
about one year) Of all the fields I've flown from around Phoenix, DVT
has a lot of camaraderie, sharing of help, tools, and things seldom used
but important... welding or trailering. Friday night and other special
days at DVT north side hangars you will find a barbecue or potluck going
on in the evening. No organization. Just show up and get acquainted.
I don't know of another field with this atmosphere. DVT is the 23
busiest airport in the US. Great tower and controllers. Always willing
to work with strangers, students, foreign students and gas stops or
EXPERIMENTALS.
Great taxi up restaurant on the south side of the field in the terminal.
E-mail me off list or come see us..
My website (I'm building a Zenith 701/Jab3300) is

You should try contacting all of them ASAP to find out how things look. The Scottsdale EAA chapter (#1217) seems to be the most active. Here's the link: http://www.acsinfo.com/eaa/index.htm Deer Valley would rank second, the others seem dead. There are a lot of warbirds at Mesa. As usual there are RV's everywhere. Pretty good group at Deer Valley, and a handful of builders I know at Chandler. Scottsdale has more varied experimentals.

First let me say, that I do have the slowest Rocket. I have flown
side-by-side with a 180 HP CS RV-4 and I am faster, can climb better, have a
lower fuel flow (maybe 0.1 GPH), etc. etc. It is not magic but I have more
HP. :-)
Now, there is no way I would take my plane to CAFE and expect to set any
records. From what little I know of John Harmon is that he took his
personal plane with no fan fare or special mods and set several CAFE
records.
Now, (I may get some of this wrong but it is what I heard), the RV-4 was
highly modified. It was build very light and not painted to save more
weight. Unlike most RVs, I would not want to be in it if acro was being
performed. The pilot even lost a lot of weight. I am sure there were many
more things done in search of the record book. Let me say, I see nothing
wrong in this. But comparing a "Stock" Rocket with a "Special" RV-4 is like
comparing apples to oranges. I don't take my car to the race track and
expect to compete with formula F-1 cars.

| Subject: | Re: Sky-Tec Starter / EI Compatibility |
--> RV-List message posted by: Rich Chiappe <service@skytecair.com>
Hey, I'll chime in on the Sky-Tec compatibility w/EI discussion.
As Dan appropriately put it, there can be issues with a starter's
initial desire to get turning ("initial inrush current") pulling max
amps out of a weakened or low battery trying to keep the EI up and
glowing during the crank. When the battery is up and the system is
functioning well, there are no problems (hence why most folks out there
are running Sky-Tec and Lightspeed together successfully). But when
something falls off par (battery low, cable or solenoid failing or
loose, etc.), when the permanant magnet motor goes to pull current,
there's not a lot left to keep the bus (supplying voltage to the EI) up
over a threshold of voltage above which it knows to do its thing. Below
the threshold, however, the EI fritzs out and doesn't do its thing well
alowing sparks before the piston gets all the way up (kickback -> broken
starter).
Workaround/fixes:
- Choose a wound field (non-permanant magnet starter)
This may work well for you for a longer period of time, but frankly,
you haven't fixed the problem - only delayed it. The condition still
exists. You simply manage to lessen the extent of the amp draw and
therefore lessen the liklihood of drawing current below the EI's power
threshold. But a low enough battery with any brand of starter will
still yield you the same results: KICKBACK.
- Don't start on the EI. If you are lucky enough to have left an
impulse coupled mag on one side of your engine - GREAT! Pull the power
to the EI until the mag has your engine lit and running (well past the
point where the starter pulls current to start cranking it up). Put
power back into the EI when everything's already going around.
- Dual EI? Then your best bet is to isolate the EI battery (give it its
own source of power separate from the big battery supplying the
starter). Again, this doesn't matter if it's a Sky-Tec LS or any other
flavor of starter. You'd be well served to protect your investment this
way. The EI doesn't require a very stout battery. Just good, clean
voltage. So it's battery doesn't have to be big or heavy (or
expensive). Others on this board can give you specifics. A lot of
these low battery scenarios also tend to involve non-standard
batteries. There's a reason gel cell batteries are used in wheelchairs
and NOT most aircraft. There are more appropriate technologies for
aircraft batteries that crank hard and are still lightweight and small.
Consider the line of AGM batteries from the likes of Hawker Energy
(Aerobatteries.com). Can anyone say "Odyssey"? I know most of you
already do.
- Consider buying an EI that understands the cranking process. As
mentioned, we have had multiple conversations with "traditional EI
vendors" and the other posts were accurate. Existing vendors tend to
blame the starter for causing kickbacks. For obvious reasons, we
disagree. The starter is the victim in this scenario, not the culprit.
However, there are other EI manufacturers that have figured out ways to
make their EI work even when voltage goes scarce during the crank (due
to starter pull or any other reason). Take a look at the E-MAG at
emagair.com .
- Go on faith. For those of you who continue to run Sky-Tec LS (or any
other model of Sky-Tec starter) with a Lightspeed, great! If your
starter should suffer a kickback, we're here to help you. Complete
overhauls on most models are $150 or less and repairs of simple parts
like mounts (most frequent victim of kickback) are only $60. It's not a
ton of money in the big picture should the worst scenario ever happen.
When it happens to your other brand of starter (they suffer kickbacks
just like all starters do regardless of manufacturer - regardless of the
hype), hold on to your wallet. Seriously, we turn starters around same
day (in most cases) and we'll work with you. If we can't be perfect,
we'll at least be nice, efficient and a good value!
Hope this info helps you. If you ever have questions about starters of
any sort, please do not hesitate to ask.

Fred,
I have the 7 row Niagra cooler on a 160 HP RV-6. It is mounted directly to
the baffle behind the #4 cylinder, and the opening is the width of the
cooler x the height of the cooler less about an inch. I'm guessing the
overall dimensions of the hole are 3.5" x 4.5", which is15.25 square inches,
which would be the same cross sectional area as a 4.5" diameter SCAT Tube.
Both my oil cooling and cylinder cooling are fine, even in the high
temperatures we experience here in Atlanta.

I can vouch for Sky-Tec's service. I just had a starter go out. I
called them on Monday. Arranged for an outright exchange which I had
to pay for, but they will refund some money if the core of my bad
starter is serviceable. The new starter arrived today. They really
wanted to help my try to troubleshoot my starter to avoid having to
send it to them. Really nice folks, really good service.

Learned this trick on the DC-6B, just count a few blades before you turn the
ignition on!
8 & 12 blades, fuel boost then ignition (3 & 6 warm).
On the RV with sky-tec and Lightspeed, ignition ON at 4 blades, no kickback
in 360 hrs.

True the sky-tec takes takes more current to get going which can draw down
the voltage
Kick backs are not Sky-Tecs problem, it is an ignition problem
If you kick back you can break the starter nose casting
Low voltage plays havoc w/ all elect ign, causing them to miss fire and kick
back during start
The LSEII (or LSEIII)

First let me say, that I do have the slowest Rocket. I have flown
side-by-side with a 180 HP CS RV-4 and I am faster, can climb better,
have a
lower fuel flow (maybe 0.1 GPH), etc. etc. It is not magic but I have
more
HP. :-)
Now, there is no way I would take my plane to CAFE and expect to set any
records. From what little I know of John Harmon is that he took his
personal plane with no fan fare or special mods and set several CAFE
records.
Now, (I may get some of this wrong but it is what I heard), the RV-4 was
highly modified. It was build very light and not painted to save more
weight. Unlike most RVs, I would not want to be in it if acro was being
performed. The pilot even lost a lot of weight. I am sure there were
many
more things done in search of the record book. Let me say, I see
nothing
wrong in this. But comparing a "Stock" Rocket with a "Special" RV-4 is
like
comparing apples to oranges. I don't take my car to the race track and
expect to compete with formula F-1 cars.

Guys,
I like to tell you about a new, improved product for our tailwheel
RV's. I have been flying with one as the BETA tester for some time
now. I previously had a Jantzi tailwheel link. I liked Terry's but
wanted something different. I asked my brother (who has a machine
shop) to make me a tailwheel linkage that was corrosion resistant
and lighter and would last a long time. The result is what he calls
the "Silver Bullet". His company is called, "RIVETHEAD." I liked
the feel and response from the new "Silver Bullet" so much that I
asked him to produce it for us tailwheel RV'ers.
Take a look at the link below. It's nice to have choices.

Can't let this pass without comment. This was the same explanation I
was given by the Skytec folks at their booth at Oshkosh. Sounds
plausible, but in talking to Klaus from Lightspeed, he explained in
great detail (which I forget and didn't fully understand anyway) why
this scenario was thought of and engineered for, in his ignition
systems. Whether you believe Skytec or not, Rich states this as
accepted fact, and this is not at all the case.

No beef up on the RV-8 spar. Will reduce max G rating to utility cat. (4.4g) This
is intended to be a high altitude traveler (18,000 ft or more). My -4 will
be the yank & bank ride. The -7/Rocket tips are the 'sheared' tips that give
another 5 - 6 inches of span (each side) over the Horner (Sp?) tips on stock
-8) Used them on my -4 as well.

Sounds very interesting. Did you do anything to beef up the
spar, or are you planning on reducing the aerobatic limits?
What's the difference between the RV7 wingtips and the RV8
wingtips?
Thanks,
Mickey

It's going to be that time before long and the list doesn't have much info
on the subject.
Which suppliers have been pretty good to deal with for standard flight
instruments? What US brands are recomended (staying away from the imports).
Thanks,
Jim
