| Subject: | Re: Engine thrust angle |
For example: if Tiger 86M were all leveled out and a level was placed
on the engine, it would read 0.7 degrees down. Hence, the statement,
"All measurements in degrees down; i.e., down thrust angle."
I understand all of that, but you still didn't answer my question: where
specifically on the engine did you locate the level? Crankshaft flange?
Top of engine case?

OK, I'll try to clarify.
When I say, "All measurements in degrees down; i.e., down thrust
angle." I mean the down thrust angle from 0 degrees. (if you wish,
Google 'down thrust angle' for a more complete description including
pictures on some web sites.)
For example: if Tiger 86M were all leveled out and a level was placed
on the engine, it would read 0.7 degrees down. Hence, the statement,
"All measurements in degrees down; i.e., down thrust angle."
I hope that helps.
Yes, when I said the accuracy was .05 degrees, that means .00, .05,
.10, .15, .20, .25, . . . . . .95, 1.00 (where 1.00 means 1 degree)

Relative to what? Top of engine case to canopy rails? You level
reads out to the closest 0.05 degree increment? i.e. 0.1, 0.15, 0.2
degrees?

I bought a digital level that is accurate to .05 degrees. Here are
the results of a few planes. All measurements in degrees down; i.e.,
down thrust angle.
Tiger 86M: .7 degrees
Tiger 6FT: .3 degrees
Tiger 747: .3 degrees
Tiger 57V: .15 degrees
Traveler 89L: .4 degrees
Traveler 62U: .35 degrees
RV4: 0 degrees.
Note: ALL aircraft appeared to have the cowling aligned with the
spinner.

If you do a google search of finding the thrust angle of the engine, you'll find
a page that says to use the top of the rocker boxes. They are level with the
crank. Canopy rails are zero on the Grumman.

Sorry, I remember now that you mentioned that you used the top of the
rocker boxes before.
