I was quoting an overhaul with LyCon recently and we got to talking about
the Roller Tappet conversion. LyCon will machine an upgrade into the case,
but it needs to be a very recently made case. In our situation the case
was 30 years old, so it didn't apply. If we really wanted to do it, LyCon
said that they could try to do a core swap for a newer case, but that it
would have a cost. Don't quote me on it, but I recall the conversion
adding somewhere in the ballpark of $10K (and I think that is with a newer
core), putting the option just about in the middle between a high
performance overhaul and a new high performance LyCon built engine.

Those recent cases are difficult to find with the core market like it
is, and there is some risk with doing the conversion of damaging the
cases, and then they have to be repaired by a case overhaul shop,
usually CSI in Sand Springs, OK.

Just got a quote from Lycon yesterday. Roller cam and lifters with the
modified case is a $3000 option. While I'm sure there is some benefit, I'm
not convinced it is that big a benefit. I tend to think flow balancing the
cylinders is a bigger benefit for less money.

| Subject: | Flo Scan K factor |
For those who have a G900X panel, have you adjusted the K factor value for more
accurate fuel flow readings? How did you calculate it? Using the K factor that
came with my Flo Scan sensor (mounted after the fuel servo, before the spider)
, I am showing fuel burn a bit greater than actual. Maybe 2 gallons more
in 60 gallons used. This is conservative, but I would like as accurate as possible
readings.
Also, has anyone measured the amount of fuel in the lines running from the wing
root to the spider on the engine?
Thanks.

| Subject: | Radio problem in Phoenix - need some help |
Coming into town a few days ago my SL30 went intermittent as we flew thru some
storms north of Phoenix. I used my G430 radio to get us in but rediscovered that
the limited range of my wingtip antenna will be a problem heading back to
NC.
After unsuccessfully trying to get some avionics help here at KSDL, my best options
appear to be 1) swap the antenna leads on the SL30 and G430 to get the needed
range and 2) buy a handheld for backup.
Re #2, I'm here long enough to have a radio delivered.
Re #1 Does anyone know a local avionics tech that would able and willing to help
do the swap. I'm pretty sure the two radios have different plugs (?) and will
require some termination work. I can do it given the tools don't have them
with me.
Any leads on local resources is appreciated.
Thanks,

Bill, if you can make it down to Chandler, KCHD, I've got connectors,
crimpers, etc. Happen to have both right and left Bill archer nav
antennas on hand, but not a com antenna. Both radios should have BNC
connector near radio tray unless they are soldered in right angle
connectors. Have avionics tech available afternoons(he teaches at local
A&P school mornings).

Bill,
The SL-30 does have a special connector at the back of the tray, while the G430
has a male BNC connector.
#1 - Getting two fully-functional, panel-mounted radios would be the best option
overall, if you have a good way of doing that. A handheld has much lower power
output than an SL-30/-40/G430, which, added to your wingtip COM antenna, will
be very far from a good option for a second radio. I have an extra SL-40 around
that I could ship to you to use for the remainder of your trip. I would have
to verify with an avionics person that it would fit into an SL-30 tray without
problems, which I could test here, since I have an airplane with each here.
I think this would work fine, since the COM radio uses one side of the back
tray and the NAV radio uses the other side. Basically, this would leave your
NAV portion disconnected, but you would still have your COM. You would still be
able to use NAV on the G430 as well as the IFR GPS. Give me a call on the number
below in the morning if I can help you by shipping this radio to you (after
I test the functionality of the swap). This is probably the most expensive
option because of shipping, although many avionics shops are very proud of their
connectors (and time, if they won't let you borrow their crimping tools). This
would also save you from having to introduce more loss into your antenna cables
by using one of the two options below. There is also always the risk that
working behind the panel can introduce more problems into the system that is
currently, apparently, working just fine. Leaving that all alone is a good way
to make sure it keeps working correctly.
#2 - Your best option short of a new SL-30, as I see it, would be to either pick
a spot where both cables are close to each other that are easy to access and
put a male-female BNC connector on each so you can change which radio is connected
to which antenna, which you can easily switch back. Overall this will create
more loss in the system, but it should be fairly low loss if you have good
connections.
#3 - The other option is to cut the cable near the SL-30 tray (leaving enough room
for a reconnection down the road) and putting a male BNC connector on that
cable and connecting it to the G430 COM port (this is assuming that there is
enough cable to reach the G430 connector). Then you could either run the G430
antenna lead going to your wingtip antenna to a location where you can hook it
into your handheld radio, or making an extension cable with a female BNC on one
end and a male BNC on the other end and run that to your handheld radio.
GOD BLESS!

I would have bet $20 that my SL-30 had BNC connectors on it. In which case I'd
say just swap the coax lines. I know the Garmin has a TNC connector at the antenna
end.

Okay, now I remember. There is an odd (RA?) connector on the back. I got my Gamin-required
wiring harness from Stein, and they wired the connector to a short
length of coax with a female BNC at its end.
So if yours is like that it's easy to swap.

Kelly, I could definitely make it down to Chandler. Please let me know what time
would be best and I'll be there. I'm pretty confident that cutting the SL30
cable and crimping on a BNC would be a sure way of having one, good functioning
radio to get home with.
Thanks much,
Bill

Jesse, I agree that #1 would be optimal. But I'm most confident trying to do #3.
At this point I really don't know where the failure is and it could be in
the audio panel or elsewhere. (the SL30 still lights up properly and looks like
it is operating, but I just get static on Rx while Tx function is unknown).
I'd love to slip a SL30 or 40 in to see what happens... But I could still be stuck
is what I'm thinking.
Would very much like to know if 40 would work though.
And maybe a handheld is a dead end.
