Larry C.
Thanks for posting your initial results of the HACman. WIth my GA flying background,
it took me a while to get used to not manually adjusting mixture when I
first started flying a 912. I still like the ability to manually adjust mixture
in-flight. When I fly really slow the Bing 64s allow the mixture to get a lot
richer than ideal. When tuned properly, they do a fine job anywhere near normal
cruise power. I may get one these someday. I believe it works on the same
principle that Jack Hart used to rig his own manual mixture control, but not sure.
At the moment, I'm not flying 'cuz one of my partners broke our airplane a month
ago (no injuries) and we're still waiting on the insurance adjuster to do his
thing. It may be totaled, may not.

Greetings,
Looking at Larry C's great pictures of his panel and the interesting landscape
he flew over brought to mind a question I've been pondering.
My Kolb MkIII-C isn't equipped with a compass deviation card.
I think that in 'general aviation,' it's required. Does this rule apply to Experimentals?
Thanks,
Dave

depends on how much of a deviate you are.
The rule with certificated (standard) aircraft is that whatever you
have stuck in the panel is supposed to be functional.
If it doesn't work remove it.
Compass card presence has rarely been enforced as evidenced by so
many nearly illegible ones out there.
First thing to do if you are concerned is lay out a temporary compass
rose on the ground using ribbon and
a boy scout compass. Then rotate the plane on it to check accuracy.
I was pleased to discover mine was nearly dead on. At least within a
degree or two.

Be careful! The "deviation card police" are everywhere.
I have tried several times to swing the compass in my mkIII, but can never
get close. It will give you an accurate reading at one point in the compass
rose.
I even used a "real" compass rose at Wetumpka Airport, but that didn't help.
; -)
Primary nav is GPS, which is not 100% reliable. It'll hicough once in a
while and leave me hanging, but only once in a blue moon. If the GPS goes
down, I can still use the whiskey compass to maintain a heading. May not
know what the heading is, but have a general idea. This will get me to a
road, river, railroad, etc. From there I can find a town and an airport.
If I find an interstate highway, it is a simple task to get down on the deck
and read the road signs. Other highways work, but normally their signs
aren't as big as those on the interstate.
My FAA Designee was not interested in my compass card, but he did a thorough
job of inspecting the aircraft, without the mickey mouse BS that some folks
have to contend with.

Today I flew to the Alvord to test fuel burn close to the ground with
the system. First I marked the front tanks fuel level, so that I could
be at least close to correct. I started and warmed up the plane using
the back tank, and when it was ready to go, I switched to the front
tank, climbing to 500 feet to activate the GPS timing system, then only
maintaining enough altitude to clear the hills between me and the
Alvord. I did not change the throttle position once I established about
5360 RPM's until I set up for a landing here at the house. I did dial in
the EGT to 1350 degrees and changed the setting to match the MSL. Keep
in mind that the higher you go, the richer the fuel mixture, so on
occasion a change was required. All of this including a couple of
video's will be posted to my blog later in the day.
The flight covered one hour and 24 minutes from warm up to landing. I
burned a total of three gallons of fuel from both tanks. I burned 2.3
gallons on the timed front tank flight, and 7 tenths of a gallon on warm
up and the extra 24 minutes.
The OAT was 70 degrees, winds mostly calm, approximately 5 MPH wind out
of the SW. Average speed of 62 MPH. The CHT's were well within limits
at around 306 degrees. A great day for flying, and I am very happy with
the results.

| Subject: | New alternate engine on my MKIII |
Well it's a long story but I will try to make it short.
A couple of years ago I finished my MKIII with an BMW R100 (air cooled)
engine on it. After flying it about 50 hours over the last year and a half,
I decided that it was not going to provide the power and reliability I
demanded. I could climb at about 800'/min but fast cruise was 60mph. I
also had teething problems that required me to work on it a lot. There have
been other successful conversions of this engine but I decided it was not
for me.
A couple of weeks ago I finished the installation of a 2005 Yamaha Vector
snowmobile engine with a Rotax 3.47 gearbox. I now have about 5 hours on it
and am ready to say that this engine just might provide me with the
performance I was looking for. My rates of climb are in 1000'/min range at
1000# gross and I can wind the airplane up to 90mph at full throttle in
level flight. I have chosen 70mph as my cruise as that is what feels good
with my airplane. Only time will tell about the reliability but I do have a
good feeling about this engine. Below is a link to a Utube video of the
engine on the airplane.

To answer your question about the gearbox noise - that noise is perfectly normal
when running the rk-400 clutch. It's normal gear noise, you'll notice it's more
pronounced when turning the prop one way vs the other, which has to do with
the helical gears. The noise is just the slight amount of lash you normally
have....

What gear box ratio?
Sounds like a good engine. Yamaha makes good stuff.
Are you able to use all 8500 rpm?
Where does it get its max torque? That will probably be where you want to
cruise this engine.
Convenient with carb heat.
Are you running oil cooler and coolant radiator?
Seems, just from looking at the video, those two coolers are going to be a
big increase in drag. Just guessing. We have good luck mounting the
coolers behind the fuselage. I even have mine piggy backed'

The gearbox is 3.47 ratio
There is no oil cooler but there is a water to oil heat exchanger build into the
engine.
I know the radiators might be overkill, but I really wanted to design a system
that would cool and not have to dive right back in if it was running too hot.
There is a thermostat in the system and the water temp is running cool now, so
after this summer, I might try just running 1 cooler and see what happens.
Cooling was one of the issues I had with my last engine and it is very gratifying
to be able to operate at full throttle for as long as I want and have the
temperatures remain well in the green.
On a side note. On one of my full throttle level flight tests, the right side
door popped in. I heard it but did not see what had happened until I landed.
I just opened the door and put some slight pressure on the inside and it popped
right back out.

| Subject: | Twinstar plans needed |
Long story short: Where can I get a set of plans for the Twinstar? What's the
difference between that and a Mark II?
Here's the story if you're interested: Just bought me a Twinstar project for $3k
which I figured if the airplane was trash would at least get me a good engine
and prop for a decent price. The ad said "I have all plans and drawings".
When I got it home and had time to dive into it, however, all that was in the
plans tube was a full-size rib sheet. I DO have a well-preserved builder's manual
at least, but that doesn't help too much without the plans. Called the seller
up, he said he actually DOESN'T have the plans but that I could get them
on a CD from The New Kolb. Sounded fishy to me, but I didn't really have any
recourse. So I calls TNK, and they, of course, do NOT have a CD with Twinstar
plans on it, but he said I could for sure get plans from someone on The Kolb
List.
SO, I appeal to your collective wisdom and resources. Where, indeed, can such
apparently rare and esoteric information be found?
Ideally, this incomplete kit will be shipped to Brazil where it will be finished
and floated and eventually used in missionary service among remote tribes on
the upper Amazon river. If you could help bring this to pass, I'd really appreciate
it!

I do have a set of plans for my twinstar mkII. But I don't have the builder's /operation
manual.
I don't have the necessary equipment to scan such large pages but I will try the
local copy shop, maybe they can help me. if I can get them scanned, would you
do the same for your builder manual?
That would be very helpful for both of us.

You can usually get a 2005 to 2007 snowmobile that has very low miles on it for
around 4K to 5K. After you take out the engine and strip the wire harness, you
can sell the parts for 1K to 1.5K so you have 3K to 4K in the engine. My entire
conversion including the Rotax gearbox was about 7K. I purchased the gearbox
adapter from a guy and I will pass along his contact in a separate post.

I believe you will find that the technology used in these engines is far superior
to what was in the 70's. Only time will tell, but I do remember the people
who were used to flying lycomings said the same thing about the "ticking bomb"
rotax 912's when they came out.
I would be relucent to condem these engines because of expierences of almost 40
years ago. Bus as I said, only time will tell.
