Hi guys

i test flew my new bird this weekend. all incedences are set to 0 and it is pretty accurate. i set the cg to about 35 %
i took off and had to trim it a fair bit of up elevator. to acheive and equal nose drop both upright and inverted i reduced the trim a little. however the elevators are still trimmer a little up. this does not affect downlines. they are dead straight down
where should i go from here ? should i reduce the stab incedence? should i leave it as it is ? or maybe give the motor a lil up thrust, the Seba way?

will be greatful for useful input.
