My 6A has manual trim and I set it at nutral for takeoff and of course
on landing, crank in a lot to basically come down the chute with
minimal stick work. Importaint thing for me is to always crank it back
to nutral as part of shut down. Early on I got a few wake up charlie's
when on takeoff the nose pops up mucho to quicko.

I have a 6A with a constant speed prop. Solo, I set the elevator trim
about three clicks nose down from neutral for take off. It makes the
stick a bit nose heavy at nosewheel lift off, but completely
manageable. The stick forces become neutral very quickly after lift
off and as I accelerate past 100 KIAS it takes even more nose down
trim to keep the stick forces neutral. With a pax, I usually position
the elevator trim to neutral; however, I find that I must start
trimming the nose down pretty quickly after lift off to keep the stick
forces neutral.
I've intentionally flown my bird with full up and full down elevator
trim at both slow and high speeds. Regardless, full trim produces an
uncomfortable amount of stick force, but is completely and easily
controllable at all speed ranges. I wouldn't want to fly long
distances with full up or down trim, but it could easily and safely be
done. I've also found that full up or down elevator trim makes not a
bit of difference in take off performance, and the nose is easily held
at the right climb angle regardless of stick force.
