Leroy, I doubt that you will notice any difference. I'm not all that familliar with the Tiger but due to it having some down thrust I am going to assume it has a semi-symmetrical airfoil. If it was symmetrical I would question the need for downthrust.
Down and right engine off sets, what determines the # of degrees in the first place. I'm going to check again, I think the wing is said to have a symmetrical shape and the plans show a 2 degree down thrust and the same for right thrust. If you change one or the other a degree what are the effects going to be ? I would like to better understand these things should I decide to design and scratch build a plane possibly taking info. from other planes. I have collected alot of info. but have nothing on thrusts.

Thanks, Leroy
