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...

While this may be represented as a comparison between engines, I have
several problems with it.
You do not fly at 0 airspeed, but that is the speed that this test was run.

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 wel
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.

I'm sure there are. I'm not an engineer but my opinion is very

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, . .

Can anyone add to this.

That sounds low. Check these tests: http://www.flycorvair.com/thrustjune.html
If someone has a accurate measuring device for this test lets do some testing
at the gathering. I would be interested in knowing how my 60" WarpDrive stacks
up against the fixed pitch props.

I'm considering an alternative engine for my KR 2, but it would require
lowering the thrust alignment to about 3 inches below the longerons. Other
than the obvious impact to prop diameter, does anyone have any experience
with this, or know of the not so obvious downsides?

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 which
prop wash.
I learned long ago that the dumbest questions are the ones not ask!

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
n issue. This was not clearly spoken but it is
my inferance to what he said.

Rumor has it that it was called a "Trauma-hawk" because it was "spin

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...

Does anyone have thoughts / experience with the best thrust line offset to
use for the KR2?
I have a suby motor with Redrive so the prop turns clockwise viewed from the
cockpit. My engine mount appears to have close to 1 deg offset to the right
built into it, but I have heard that 3 deg is likel
This has been discussed in the past and I know of no offset being
recommended. I have a 100HP Corvair on mine and unless WW built in an
offset, which I am sure he did not, there is no offset for that awesome
power.

Good to know the aircraft works fine with the crank centreline on a
