Hi all I am about to start work on my engine mount ( diehl case 2275 vw ) will
I need to factor in a thrust offset or not ? Also what length mount are you
using ? The plans say 6 1/2 inches but I am thinking with a diehl case and
starter it will need to be longer. All thoughts appreciated

If you go to my webpage you can see pictures of the fixture I just built for my
O-235. They are listed under the 3/11/15 update.

Thanks Larry and those that responded. The plane is already built but no
engine or mount. It was originally built with a 0-200. I am putting a VW
1835 on it. Insert sad emote here. I am going to build an adjustable jig.
You thought I was going to say "engine mount" didn't you. Ha ha ha, . .

I'm sure there are. I'm not an engineer but my opinion is very
affordable. The plans
If I recall correctly (from about 1989) I tried to get the engine thrust line
at center of crankshaft to line up with the top longeron. I did not offset the
engine laterally to compensate for p factor like I have read that some planes
do. Too much math for me.

So, no one wants to wade in on the thrust line on the fire wall for a KR2
huh. No Aeronautical engineers out there.
I'm not an engineer but I've been in the presence of a few. I was told the
thrust line is typically in plane with the top longeron. I set mine at 2.5"s
below to accommodate the Corvair and the starter. Check out the KRnet Archives.
Type "thrust line " in the email body section and watch the
How do you locate the thrust line on the fire wall. Makeing my own motor
mount.
When I run up my 2108 VW on level pavement, the nose will dip down and the
attitude gyro shows the number of degrees. Shut down I hung weights on the
crank shaft to get the same nose down pitch. Using similar math as for the
weight & balance measurements, I calculated the thrust to be 203
Hi Guys;
I have worked on engines of about all kinds in my lifetime and many different
kinds of vehicles and machinery. I have driven, boated and flown many of them
as have many of you but the only thing that I can think of that still amazes me
is that every time I'm on an airliner and we pull
can anyone informed tell me what the thrust line is supposed to be on a
standard kr 2
where is it measured from

Without looking back at the plans I believe it should fall in the

The Top of the longerons ???is the normal thrust line. I do remember a
number of builder changing , including me. I lowering my thrust line about 1
1/2 inches below the longerons to allow the twin top mounted carbs to fit
under the cowl line.
But One of the Famous Mark's Brothers, sorry

Below is a post from 2005 that I found in the archives

Famous, ha...maybe crazy..mine is set 1 1/2 inches below the longeron.

Something else came to mind the other day when considering the effects of
raised or lowered thrust line. During flight training to become CFI's we
were always told that the reason the Piper Seminole was made with a high "T"
tail as compared to its sister plane the Piper Seneca

Funny, my instructor called them the "Trauma - hawk" because of the T
tail being less responsive to prop wash when you need it the most -
stall recovery.
Raising the trust-line I would think increases the loads on the upper
half of the firewall. Maybe not enough to worry about, but I sure like

I learned to fly in a Tomahawk. Didn't realize landings were easy till I

Rumor has it that it was called a "Trauma-hawk" because it was "spin
friendly". :-)

Steve,
Those things had (have) so much thrust they didn't even need wings. Like the
F-104 proves. Of course, the wings do make it easier to land...

I have been looking for info on the correct thrust line, Others have talked
about the
T/L being equal to the top longerons, If I fit my engines cowls and sort out
he centre of the prop outlet, the T/L seems to be approx 1 - 3/4 inches
below the T/L.
Can anyone add to this.

I know I have seen this mentioned before both here and noticed it in web sites,
but have not noticed it in the manual or on the drawings. I take it I am
missing something here as everyone that has built their plane had to figure
this out. Langford mentions being high or low from the main

I guess I should have answered your question, which is that it's generally
considered to be in the same plane as the top of the top longeron. That's
been arrived at by the fact that if you buy an RR or Revmaster cowling,
that's where the center of the prop hole ends up, blah, blah, blah...
