As to right thrust,it needs to be there to offset engine torque that at low air speeds where the wing is not at a good flying speed and can not do this on its own. So you put in right thrust. Have you seen a jet with built in right or left thrust? Unless you go jet, I don't think there is any one for all speed thrust angle. I know in full scale light planes ,you trim for level flight when you reach cruising speed,but if you cut the power down you start to go,then you have to correct your flight pass with your elevator. I suppose that one plane design can act different than another. All depends on how the aircraft is set up.
