This is not meant as a direct challenge to-reported empty weight claims m
ade by an individual builder-but in my experience, I take most such repor
ts with a healthy dose of skepticism.-Out of denial, people can fudge the
numbers when they get on a bathroom scale in the morning. -In the certif
ied world of production aviation, the only reliable and accurate measuremen
t is derived from using-certified scales and because of cost, most RV bui
lders do not use certified scales. -Everybody is not on the same page. Th
e absolute worst-type scales are the so-called Ruggles scales-Aircraft
Spruce sells.- Relatively inexpensive, they are little more than bathroom
scales with a lever type extension that acts as-a-multiplier. So inacc
urate, when I weighed my -6A using Ruggles scales, I had to move the aircra
ft on and off the scales TEN TIMES because I got a different reading each t
ime.-There was a 40 pound spread between the high end and the low end of
the
readings. -I ended up accepting-an average to satisfy completing that
part of the documenting process.-I openly wonder how many builders would
use the lowest Ruggles scale measurement and then proudly tout how light th
eir RV is!- Since that time, I weighed-my -8 using far more accurate di
gital scales that our EAA Chapter invested in.- Just for grins, I did thr
ee separate measurements and the total weight did not vary by a single poun
d. Still, our EAA Chapter approved scales are not certified scales but I am
satisfied that my claim (1106 #) is-about as accurate as you can get sho
rt of shelling out $100 or more to use the regulatory standard: certified s
cales.-

Just currious Rick, how did the EAA scales compare with the Ruggles average
weight?

We used Ruggles, then 6 months later used certified scales. In our
case the certified was 50 lbs lighter!!! And of course more
accurate. I agree the Ruggles are highly inaccurate and not very
repetitive, and when you multiply by 2 for the moment arm, you are
doubling the error!

I think that he is talking about the rear pedals. In a strong gusty
cross wind, I could see how they could be bent.

Shameless plug. Check out our steering linking for the RV series of
planes. The link is light and easy to install. You can get rid of
those pesky chains and get very positive steering in each direction.
Once you experience a steering link, you can never go back to chains.
Also, a must have is our pedal extensions for the 6/7/9 and soon for
the 8 and 10. The extensions improve the geometry between you feet and
the brakes. You will no longer drag your brakes or have your feet at
some unnatural angle to avoid the brakes. Those who have them have
wondered how they flew without them. The extensions install in
minutes!!!

Darwin...
Along with your shameless plug... How about a shameless subjective comparison
between jdair and "The Rocket Link"? I have the Rocket Link, but have not flown
it yet. Reports that have surfaced here indicate a short life ~150 hours.
Have you compiled data on cycles or hours?
Always looking for better performance and value...

Anybody follow the Red Bull Air Races the last couple of years, Mike
Mangold has his spare engine from his race days for sale.
5 hours since Performance Engines rebuild. 320 HP, 10:1 machined ECI
pistons and cylinders Narrow deck. Lots of extras.
I am not on the RV-10 list, so would someone please let them know that
this engine is available.
He was asking 38,000 but has dropped to 36,000 USD. (Claims to have
over 45,000 in the engine)
If there is any interest, I can copy and sent a PDF of the description
of all the engine components and the contact info for Mike.
The engine is "preserved" and has a large wooden crate for shipping and
is located at Apple Valley (APV), CA.

Group=2C
I just had an A & P take a look @ my O-320-B2C=2C and he informed me
that neither one of my mags have an impulse coupling. This engine came off
an R-22=2C so apparently it used "shower of sparks to light off the engine.
I do have the coil section of an Electroair Ignition System=2C which would
need the mag replacement portion purchased from the manufacture. The quest
ion is what options do I have to complete my ignition system? I have an S
4LSC-200 on the Left Side=2C and S4SLC-204T on the Right. It would cost apr
oximately $550.00 to complete the Electroair System=2C and about the same t
o repuild both mags. The mechanic suggested the possibility of trading one
of the mags for an impulse mag. If anyone is interested in that option=2C c
ontact me off line. Your input is appreciated.

You should be able to find a Bendix vibrator used. IMHO the shower of
sparks system is more reliable and trouble free than impulse couplings.
Most impulse coupling mags at one time or another have had ADs against
the impulse coupler. You don't need a special ignition switch, like the
certified planes do. You just need to be able to turn the vibrator on to
start, and off after start. I have the same model mags on my 200hp
Mooney. Work great.
