Hi
I discovered something today that has helped in flying the P-51D big time. For context I fly the sim on maximum realism with rudder assist turned off in the miscellaneous options section for the P-51.
For years in various simulators I've mapped trim to a hat switch so that I can use it just like in modern aircraft. However, it's always been annoying that unlike a real aircraft you can't feel the pressure being relieved from the stick. However, today, because the P-51 has trim dials that you turn, I thought why not map my elevator and rudder trim to the two axis rotaries on my stick. I did it as a fancy, not expecting anything, but I was in for a surprise! By putting the elevator and rudder trim on an axis each flying the P-51 straight and level while changing power settings rather dramatically became effortless. That "feel" that's been missing was suddenly just there. It's as easy as flying with rudder assist turned on. Lining up for landing with the power at minimums to hold 120mph, easy. No more wobbling. Also, now that I have analogue control of the rudder trim I find I have almost no need for the aileron trim any more barring weapons release. Probably more correct to say I was using aileron trim in the past incorrectly!
Before this I had trouble transitioning from full mil 61/30 to max continuous 45/27 without the plane bobbing about like a frightened pony, understandable given that the X-65F is a centred stick, but annoying when part of your hobby is trying to fly the plane just right. Now, no longer a problem. A little change that made a HUGE difference.
To those of you who have been doing this all along simply ignore me. But to those who've been doing rudder and elevator trim on hat switches and buttons, please do yourself a favour and try it on an axis for the P-51. I suspect you'll be pleasantly surprised.
There is one tiny caveat of course, before take-off (or even more importantly when jumping into the cockpit mid-flight) you must remember to centre your trim axis on your controller. Otherwise she may just throw you right off!
Hope this is useful to someone. Happy flying!
