 Hi,
 
 Failing to get the performance I need from C172P, I decided to try 
 C172R, it seg faulted with this output:

 Just thought I would let you guys know.

The thruster file is available here:
http://cvs.sourceforge.net/viewcvs.py/*checkout*/jsbsim/JSBSim/engine/prop_Clark_Y7570.xml?rev=1.4

Save it to $fgroot/Aircraft/c172r/Engines/prop_Clark_Y7570.xml

 Thanks for the file. It fixed the seg fault.

 But C172R seems to suffer the same lower-than-RL max RPM as C172P (2200
 vs 2400), and as such cannot climb at the expected rate.

 Do they share some engine spec file that may have been modifed recently?

 Yavuz Onder

I don't think so. I've got a fresh build from a couple of days ago (from
FlightGear CVS). I'm showing no differences between my base package and CVS
for the aircraft and propulsion. Using the default startup:

fgfs --timeofday=noon

I get 2500 rpm and 1000 fpm climb rate off the runway at 70 kts. I don't
know how close that is to actual.

Jon
