Well.. trim on the P-51 is on yer left, dial for the rudder, one for the ailerons, and a wheel for pitch.
You get used to dropping left hand and adjusting what you need in very little time.
(like .. during first climbout .. f'rinstance)
I got a kick outta Lee tellin me 'You will have to *TRIM* thru this manuever' as we setup for a split-S from 8500' agl.
Yassir .. it takes approx 50 lbs of stick pull per G in the Stang. A 4g pull ..well .. you brace both feet on the pedals, both hands on the stick, and PULL .. HARD .. or .. you can drop left hand and crank in trim while keepin wings level for pullout ..then crank out trim as you level and slow down.
Lee informed me I could solo the Mustang with another hour of instruction .. after spendin an hour in it.. my only problem was finding the actual indicator that I needed right when I needed it ... LOL .. altimeter, airspeed, .. stuff like that .. took me a few seconds

As for takeoff .. well .. I was hands on .. you crank in 6 degrees of rudder, manifold pressure and rpm smoothly to 55" and 2700 rpm and you really gotta be on the rudder nudgin here an there as she rolls up to rotate speed.. we took off on grass ..Lee said it was a lot easier than pavement ..not as twitchy.
I *loved* 'departing pattern altitude' with a sharp break to right, roll left, and buzzin the field wavin the wings to those below as we left the area. (all well above 500agl of course)
