Generally speaking, you will establish level flight with pitch, adjust

How sensitive is the trim? *I find myself wondering this as I adjust trim in
the sim. *The sim seems a bit coarse, although I'm doing much better at
holding altitude in the C182 (which has no altitude hold for the autopilot)
than I was doing a week or two ago.
When I leave the runway, the aircraft (C182 or C172) seems to climb very
briskly with take-off trim set. *After climbing a few hundred feet I find that
I must hold the stick forward and trim nose down significantly in order to get
the aircraft to level off a bit. *This is with full throttle (and pitch all
the way forward, in the C182). *I'm not sure if I should just continue
trimming to level flight with the throttle set forward, or back off on the
throttle substantially to maintain altitude. *I also don't know if this brisk
climb behavior (with full tanks but just me and equal-weight ballast in the
right seat) is typical of the actual aircraft (I have had mixed replies to my
various inquiries).
I know you are supposed to use the stick to adjust to the correct
altitude and then trim but I must admit to cheating a bit and just
playing with the trim only until I get the altitude nailed. And I am
very curious about what you use for ballast in the right seat Mx? Are
you using one of those "Skyguy" co-pilot dummies with the uniform
that you get from the pilot shop? I used to have one myself but it
was a pain carrying it around , so now I just use an 80 kg block of
lead, since it was the densest object I could find. Do you know of
anything denser so it wont take up as much room in my flight bag?
