Andy Ross writes: In this case, the pull you are seeing is the engine torque. It is a rolling moment, not a yaw, and thus you want to be correcting against it with aileron trim, not rudder. The 172 has very little (zero, in the current model) dihedral, and therefore there is almost no

To be fair, however, what many people call unflyable around here isn't anywhere near the case. The most recent JSBSim complaint, for example, only took two clicks of keyboard aileron to correct at climbout speeds. I was talking to a pilot friend of mine the other day. He was telling me that

The YASim C172 idle is better -- it's down to 1000 RPM -- but it's still about 200-300 RPM too high based on what I saw yesterday (this is at an airfield under 400ft ASL). All the best, David -- David Megginson [EMAIL PROTECTED] ___
