Staying busy and getting older, Bill.
For everyone's information, Sam Hodges flew his very nice looking
Renesis powered RV-7 to Oshkosh this year. Some of you met Sam at the
Paducah fly in back a “few” years ago. I guess lack of any rotary forums
made it difficult for Rotor heads to find each other in that
crowd.
Me, I’m still selling an occasional EFISM, but mainly focused on a
new version of the EI Commander, my ignition monitor and controller developed
for the popular electronic ignition – the Pmags. New version has a much
larger screen 2.4” vs 1.5” and I am currently working on a Knock Sensor feature
for the Lycoming crowd. Some fairly recent developments in Knock sensors
and processors makes it appear that this may be doable. IF it works out,
the Lycoming crowd could safely run more ignition advance than they currently do
saving some on few and adding power – IF it works out.
In any case, the research and work keeps the old brain from locking
up.
But, I do miss being a more active part of the rotary community – my
heart sort of got broken when Mazda decided not to make the new 16X
rotary. I already had my pennies saved up to buy a crate engine – ah,
well.
I do have continue to monitor and enjoy the list – keep it
going

Dang! Two guys we
haven’t heard from in a long time coming out of the woodwork at the same
time!
Lynn and Ed! What
has been going on with you guys lately?

The Ross unit had no
thrust bearings and used the engines thrust bearings for that function. OK on
most engines where plain bearings control thrust but in the rotary small needles
do that and cannot survive long.
Tracy's units have a thrust
set installed.
Ross units built after
the principal died had suspect
quality.............

I flew around 200
hrs with the Ross
Drive before finding that the sun gear was
galling. Apparently marginal lubrication in some of the Ross units was a
problem.
By that time,
Tracy had his Re-drive on the market, so rather
than mess with the Ross (still have it), I purchased one of Tracy’s and never had a
problem. Well, one – I had the entire aluminum area nickel plated for
corriosion and appearance. They erroneously coated the inside of tunnel
for the shaft area of the nose part reducing the area for oil
flow. Went out one morning and noticed that it was hard to pull through,
I tried to start the engine and it rotated a few degrees and just
stopped. Fortunately, I desisted at that point and stopped. Got
out and found the prop frozen. Took it off and shipped to Tracy, he milled a few
1/10000 off the inside of the shaft tunnel and I now have around 400 hours on
it. Love it!

I stand
corrected. This drive would only have a couple of teeth in contact at
any one time. How many are in contact with the
RD1-C?
What was the problem
with the Ross if you know?

No,
Tracy started off with a
Ross
Drive …
The Marcotte
drive is a different configuration than Tracy’s “Ford-6” planetary gear

Jeff,
If I am not
mistaken, Tracy started off using a Marcotte drive
on his RV-4. That drive I think is what inspired him to develop
his own drive. It would take a pretty bad experience to inspire me
to that extent! :>)

I see the
aircraft was equipped with an Aluminum Propellor – which may have lead to the
prop shaft fracturing?
I can’t vouch
for the “Marcotte
Drive” but Ross Parnham (referenced on
this list for P51 style radiator install) uses the Marcotte
Drive on his Subaru-powered RV6, mated
to a composite prop. The website shows a picture of re-drive and bell
housing mated to a 13B … http://glasairproject.com/Marcotte/index.html

Search YouTube under "LS1 Glasair 111 at
Paducah, Ky" for a video of this a/c idling.
You can hear him saying the PSRU builder is "belly up".

That looks a lot
like the gearbox that failed, killing the pilot when the engine disengaged
from the prop and he dead-sticked it into a hotel building. It was
about a week after the alternative engine fly-in at Ed's place in
Paduka, KY. As I recall, it was a Glasair
III with a turbo-charged LS1. I have video of a ground run around here
somewhere. Real sad story. Can anyone confirm whether or not it
was the same make psru? I never read the final accident
report.

I went back to
the exhibit buildings, and took some photos of the psru’s offered by www.autopsrus.com . I will forward these later today as
every thing gets transferred . They are spur gear drive, have there own oil
supply and pump, use pressure fed roller bearings, will provide oil for a
constant speed prop, and are available in many reduction ratios. They make a
unit that can be straight through, suitable for the 13-B, the casing is CNC
machined. They use a flywheel for the torque damping, and it has a
centrifugal clutch that disengages the prop below ~900 engine rpm, so when
starting there is no prop load. Will likely be heavier than
Tracy’s
I have to reduce
the size of the pictures before I can send
them.

Anyone or everyone in Oshkosh?
That is very interesting! Could one be built specifically for my combination
of a high HP 20 B? I would have more peace of mind knowing how it was put
together by me along with your knowledge and experience. The thought of
someone just starting out making them does not sit well with me as they are
an unknown.
Let me know what you think and I will be in
touch.
The design is
royalty free. Anyone who wants to build it is more than
welcome. I can help with info if you need
it.
