Unable to log Engine Thrust of Piper J3 Cub

[Nishanth1711]

Hello Flight Gear Community

I am trying to log the Engine Thrust of a Piper J3 Cub from the path specified in the $FG\data\Docs\README.properties
/engines/engine[%d]/thrust_lb

Since Piper has a single engine I modified it in my Cub-set.xml and replaced %d with 0 and ran the flight. But no values are getting logged in the CSV File

I also tried it with different no of engine values, Yet nothing was getting logged

Kindly help me

<logging>
<log>
<filename>controls.csv</filename>
<enabled>true</enabled>
<interval-ms>500</interval-ms>
<delimiter>,</delimiter>
<entry>
<title>thrust</title>
<property>/engines/engine[0]/thrust_lb</property>
</entry>
</log>
</logging>

<property>/engines/engine[0]/thrust_lb</property>

try "/engines/engine[0]/thrust_lbs" instead

Hello FlugHund

I tried with thrust_lbs as u suggested . Still no luck. Nothing is getting logged

You might still have the wrong property. They can sometimes differ a lot between the aircraft. A good tool for hunting down the relevant property is the in-sim property browser.

The only thing I can imagine right now is that even engine[0]/ and engine/ should be the same, sometimes they just aren't. So "/engines/engine/thrust-lbs" as a last option to try.
Oops, just saw, also no underline between thrust and lbs.
If that still does not work, check the fgfs.log. Mayhap you have to increase the loglevel in order to get a message about your logging stuff.
