Have a look at these: Elevator: http://www.zenithair.com/zodiac/xl/pic9601z/elevator-trim1.jpg Aileron: http://www.zenithair.com/zodiac/xl/pic9601z/aileron-trim1.jpg The trim tabs are small adjustable surfaces on the main control surface. The trim adjustment doesn't alter the entire control surface. And just for fun, here's an elevator trim tab that's been ripped off at the Reno air races (looks like a modified P-51D): http://www.avweb.com/articles/reno98/dsc066.jpg -- Cameron Moore [ So what's the speed of dark? ] _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
