The trim wheel in my default 737 has a very small travel arc.All other planes have full range.The AP is off.Could I have something else activated that is causing this?Thanks,Ron

Are you unable to trim the aircraft in manual flight?  Just checked default 737 trim wheel, max trim available is showing as +/- 20 degrees.  If Elevator Trim Effectiveness in the .CFG file has been reduced too much from its default value of 1, it may be possible to "run out of trim".  In the 737 I have this value reduced to 0.4 but works ok.

Thanks for the response.I p,d around with this all night and found that I deleted the default 737's except for [.0] .and just had my 2 textures for SWA & Air France.When copied the default ones back and just added my 2 everything is good.I love solving problems,especially the ones I create.Ron
