| Subject: | Avoiding a Flip Over? |
Flyers and builders of Van's RV "A" models, I flipped my aircraft over and
face a major rebuild. I wanted to send a message to the digest to give a
heads-up to those of you who don't find the time to dwell in the forums.
There is a device that could save your lives and could have saved major
expense for me. It's called the AntiSplat device from AntiSplatAero. I'm
convinced that my flip over could have been avoided if I'd had this. At the
same strip two days later the identical aircraft arrived, an RV-9A, and they
had AntiSplat fitted and had no problems on this somewhat bumpy grass strip.
I could also improve my piloting skills, but that's a different chapter. At
least the five-point harnesses did a great job. Snug 'em up tight folks,
and carry that escape tool. It turns out that when you're upside down the
canopy won't move, slider or tip-up, and the canopy is already smashed so
the tool you need to get out is something that will snap off plexiglass.
Also, don't expect to have the presence of mind to pick up your favourite
escape tool before you undo your harness and land on your head, which might
just disorientate you a bit, or even turn you around.
A really pleasant surprise was to discover that the RV vent design results
in no fuel loss when inverted accidentally. We saw a small amount drain out
when the plane was righted, but while inverted it's good to take stock of
the situation in the knowledge that you probably don't have fuel leaking.

| Subject: | Engine mount bolt sizing |
I have my engine and prop back from inspection after getting hit by the hangar
door (tornado, derecho, straight-line winds).
With only 168 hours on it - I'm going to re-use the rubber Lord mounts - but I
am replacing the bolts, castle-nuts, and cotter pins...that brings me to my question:
When I originally installed the engine, I used the sizes specified by the plans
(AN7-43 for the uppers and AN7-44 for the lowers). In order to get the hole in
the AN-310 castle nut to line up, each set took an extra (meaning a total of
two) AN960-7 washers 'under' each castle-nut. It was not possible to get a standard
wrench around the top-left castle-nut to tighten it. Since each set required
an extra 960-7 washer to get it to line up, can I use one size shorter bolt
for the re-do and eliminate the extra washers all around - also allowing me
to get a regular wrench on the top-left nut???

Just curious if you had the MATCO "fix" installed, replacing the designed
axel. When Alex Peterson diagnosed the problem with the nosewheels as
designed a few years ago, and a fix was made available, suddenly a lot of
reports of nose-gear flips seemed to disappear, pretty much confirming -- it
seems to me -- Alex's diagnosis that the design from Van's imposes a
"breaking action" with the puck that seemed to be alleviated with that fix.
I've heard tood things, too, about the AntiSplat, but I'm wondering if my
anecdotal evidence of a decline in flips suggests a fix already existed that
worked?
So sorry about your flip, but glad you're OK.

Hi Ralph
The proper length bolt will prevent any threads from bearing inside the hole which
will damage the mount. If after you intall a shorter bolt all of the threads
are out of the hole you should be fine.
However, in the case you are describing I suspect if you use shorter bolts you
will end up with threads in bearing which is a nono.

Hello Ian,
Thanks for the post. I can really sympathize with you. I had a nose-
over about 4 years ago. Took about $10K and 3 months to get
back in the air. I slid off my runway making a turn in wet grass. Why
didn't I just shut it down? My thought was if I get this thing stuck
it will take me a half hour to get it out! I don't blame the nose
gear design for my poor groundmanship, but several other flip-overs
have happened around here which have made me afraid of my
wonderful RV -- to the extent that I don't want to offer rides to friends.
I just ordered the AntiSplat Nose Job for my RV-7A
based on reading not just your post but also reading posts and watching
the videos linked from the Vans Air Force site. I was off list for the
past
couple of years so I wasn't aware of this device until now. It sure looks
good. This looks like the best improvement to the fragile nose
gear design out there so far. If any of you nose wheel drivers haven't
seen the videos mentioned above, you should. The one about the test
fixture is especially enlightening.
Anyone flying an -A model RV needs to be extremely careful because
this type of accident happens when you least expect it. In my case I
didn't flip clear over, but still had to tear the engine down and replace
the
propeller, engine mount, firewall and lower skin to fix the airplane.
Others around here have not been so lucky. Two recent nose-overs
resulted in total airframe losses.
Thanks again Ian for the post and best of luck as you start the rebuilding
process. Seriously, if I had it to do over again, I would take this
opportunity to convert it to a tail dragger.

| Subject: | Garmin 696 XM music question |
Hi Mike,
I can't really answer your question (was waiting and hoping someone would).
I cannot imagine how adding a resistor (cutting the signal strength) would
increase the audio level.
The following is a link to what I did to get music into my head - Vx
Aviation ASX-2B. Obviously, our setups are very different but I am happy
with this product if it can help you (not related, just a happy customer).

--> <n223rv@wolflakeairport.net>
I have a Garmin 696 with XM music and I can't seem to get the sound loud
enough to hear consistently. I have it going into the music input of an
Apollo SL-15 audio panel.
What I need is a way to amplify the output of the 696. Does anyone have any
ideas? I thought I heard of a way to add a resistor or diode or something
somewhere and it would increase the output??
Any advice would be greatly appreciated.

Hi Paul,
I purchased Naviator a couple months ago. I'm running it on a Samsung
Galaxy Tab 2 which is a 7" tablet. I fly VFR only so my need is for
sectionals. I am happy.

You might try the application "Naviator" on your Nexus tablet. There is a
30 day free trial in the Google Play store. I'm still in my 30 day window,
so I don't know if I'll pull the trigger on it or not, but I think it is
certainly worth a look.
I'm in no way associated with the product. A friend just recently mentioned
it to me, so I thought I would pass it along. I would be interested in your
evaluation if you do look at it. I've tried it on a 5" device which is just
too small.

Subject: RV-List: Nexus 7" Tablet / 8" iPad
I flew several times recently with the new Google Nexus 7 tablet mostly for
listening to music through my Bluetooth routed to my audio panel. What
struck me is how nearly perfect the 7" tablet is as a kneeboard replacement.
That being the case I have a feeling that when Apple comes out with their 8"
iPad mated with Foreflight or ??? that may be a very nice choice for cockpit
use as the 10" iPad always seems to be a bit too large and in the way.
