Congratulations DAN CHECKOWAY on receiving special recognition in the June issue
of FLYING magazine (page 18)! Thanks for the web-work: It's so helpful to
have another source to go to when I'm looking for an answer...

Hi,
Just curious - how can one tell the difference
at a glance between the various side by side RV models?
I know that if it's a taildragger it's not a 9,
but that's about it.
Thanks,
Mickey

The 7 and 9 have larger wing span than the 6. The also have counterbalanced
rudders which the 6 does not have (probably the most distinguishing
feature). The 9 tends to stand a bit higher on its main gear than a 6
giving it a bit of horizontal to nose down look. The 9 has flap fittings
that are visible under the wing, the 7 and 6 does not. Just a few of the
things I could think of.

If it is a taildragger it might be a 9. To tell the difference in a 9 and a
7 you look at the wing chord (less on a 9) or maybe look for the protruding
flap hinges or rectangular horizontal stabilizer on the 9. A 6 has a much
smaller vertical stabilizer than the 9 and 7.

Mickey, You need to note the difference between how the seats are arranged
to start with. RV4s and RV8s have tandem seating (front and back). The
difference in the 4 and the 8 is the shape of the rollover bar and the front
of the cowling. With side by side seating RVs you have RV6, RV7 and RV9.
The RV9 wing is longer than the 6 and 7 and it is only offered in nosewheel.
The primary difference in the 6 and 7 is the shape of the wing tips,and the
7 has a larger rudder. Both the 7 and 9 rudder trailing edge end with a
knife's edge of two aluminum sheets coming together. The 6 has a rounded
trailing edge on the rudder. There are other differences, but these are the
primary ones I use.
Keep in mind, you don't see many 9s and you don't see many 7s today. But
this will change drastically over the next few years as hundreds of new 7s
are completed and start flying.
You can't tell which plane is which by looking at the grins on the pilots'
faces. They are all happy fliers.

If it's a tail dragger, you know it's not a -9A, but it could be a
-9. The first customer built RV-9 (i.e. the tail dragger version)
flew recently.

Not true in all cases, my -6 has a -7 rudder and vertical stab. :-)

I am not sure how to tell you to tell them apart, aside from the obvious
longer wings on the RV9/9A. Older 6s and 7s have a smaller rudder, but
Van's has specified that the rudder should be replaced on the 7s with
the 9s rudder. So, a smaller rudder shows it is not a 9, but a larger
rudder doesn't necessarily mean it is a 9.
However, the RV9 does, in fact, come in a taildragger version - so the
one thing you know is wrong :-) . The RV10 is the only one that
doesn't come in a taildragger version.

I came across this item while looking at cellphones. I have not seen it
mentioned on the list before and was wondering if anyone has checked it
out. The older model appears to be an analog phone/gps. There is a
streetmap version and a pilot version. The newer one, called a NavTalk
GSM has quite a few features rolled into it including a pda. Is there a
pilot version? Any comments?

Gang,
I'm going on vacation to New Mexico in about two weeks. I would be interested
in meeting some locals to discuss the "RV flying experience" in the state as I
might eventually move my family and my RV-6 to New Mexico.
Please contact offline.
Thanks in advance.

Not necessarily true. The later 6s started shipping with the larger
stab and counterbalanced rudder (the -8 tail.) Mine is like this,
bought the tail kit in August '99. So there are three different
possible VS/rudders on 6s.
If you really want to tell the difference- look at the rivet lines. If
they line up perfectly, it is a 7 or 9. If they wander around like
drunken worm tracks, than it's a 6. At least, it could be my 6... ;)

| Subject: | Wing Skin Install question |
--> RV-List message posted by: "J D Newsum" <jdnewsum@qwest.net>
Looking for advice on installing the top outboard wing skin on a RV6 QB -
specifically where the top wing skin (W-603)and the leading edge skin
(W-601) butt together along the front spar web flange (W-606).
In the George Orndorf QB construction video, he dimples the skin and
countersinks the wing spar flange. He makes the countersinking the spar
flange part look easy but this looks tricky to me as the flange is only
0.040 thick and only 1/2 wide (not enough to support the width of the
microstop countersink tool).
The QB construction manual describes a method that calls for dimpling the
rivet holes in 0.040 spare flange and additionally countersinks the dimple
in the spar flange to slightly deepen it. (If I am reading the manual
correctly)
Also, should the edge of the W-603 skin along this rivet line need to be
rolled so that it lays down flat?
Any recommendations (do's or don'ts) advice would be appreciated.

Greg,
RV activity in NM is rather modest, but it is growing. Maybe a dozen or so
in Albuquerque and various others scattered about the rest of the state. We
just started a NM RV builders group based in Albuquerque. Link is on Van's
company page. The Land of Enchantment RV fly-in is a tremendous event and
gets better every year. It's held down south in Las Cruces. Had a couple
hundred RV's there last year. Acres of RV's on the ramp. Wonderful!
Let me know if you need further info, or have any tourist questions.

Sounds like a sampling error.
To measure RPM, it'll count the number of pulses in a fixed period of
time. If, at the beginning and end of the period, pulses happen at just
the right time to be counted, then the count will be one greater than if
the first or last pulse was a fraction earlier or later. This count will
be multiplied by 10 or 20 or 30 or whatever (depending on the counting
time period... a shorter period will give a more responsive tachometer,
a longer period will be more accurate) to scale it to RPM. Assuming an
RPM of 2500, wandering 20/30RPM is an error of about 1%. What accuracy
does the manufacturer claim?
OTOH, it could be a mechanical thing where your RPM is actually varying
a little. I assume that your tests were whilst airborne, and that
therefore the engine was completely warmed up. But did it stay the same
temperature? If not, variations in the engine might account for the
change. Or there may be changes in load... how about the mechanical fuel
pump (does it's load vary?) or alternator (using radio or flashing
lights or other intermittent electrical equipment?) or changes in
airspeed (due perhaps to turbulence)? If you have a CS prop, then slight
variations in its pitch might account for the RPM wandering.

My Lycoming O-320 runs strong and trouble free...no problems....but
there is one oddity that keeps nagging at me...since I installed a
digital tachometer I can see that the engine RPM wanders up and down 20
to 30 RPM with no throttle, mixture, or altitude/attitude change...I
firmly locked the throttle and mixture so they couldn't move and the
rather slow movement still continued...using dual electronic ignition
system....the drift in RPM occurs over a four or five minute period
typically.

You are correct that the plans for the aileron changed and the nut to
platenut was one of the changes implemented. I found this out last
night when I was reading ahead on the aileron assembly to figure out
what I needed to do today.
My Preview Plans for an RV-8 purchased in Feb 2003 have the 8/18/00
version of DWG 13A (Aileron Assembly for RV-7,8), while my wing kit
which arrived in August 2003 came with a full size DWG 13A dated 3/5/02
(Aileron Assembly for RV-4,7,8). in the comment block of the new
drawing, it says, "R1 - Drawing completely redrawn". Van's made a
couple changes and added the RV-4 to the 7,8 for a common aileron
design. My preview plans show a notch cutout of the inboard rib to be
able to install a nut behind the middle bolt on the inboard mounting
bracket, while the new plans have this setup as a nutplate. The text
from Section 7 on wing construction was not changed. Both the preview
plans and the wing kit came with Sec 7 dated 1/22/03.

| Subject: | Bending SS hinge pins |
--> RV-List message posted by: "Larry Bowen" <Larry@BowenAero.com>
I'm inserting my horizontal hinge pins for the cowl from the cockpit, rather
than from the front of the cowl... ala Danny King and others. I'd like to
bend the aft end of the pin into a nice circle for use as a finger pull.
Initial attempts at bending this stuff have turned out pretty ugly. Heating
with a propane torch hasn't helped much.
Does anyone have any ideas on how to best do this?
Thanks,
