I'm building a Kadet Senior with some slight modifications. I have one already that has less down thrust than what the kit says it should have. The plane has a 91 OS 4-stroke on it and flies great. On my new plane (kit), it calls for a lot more down thrust and I'm trying to decide whether to go with the suggested down thrust or mimic what I've already got in the other plane I've already flown.

This plane will also have a 91 on it and I intend on flying it the same way, low and slow. I like getting the plane to stay in one place when flying into the wind and I like flying slow and low (close to the ground) I do use full throttle once in a while, when going straight up but mostly, i'm just a couple of clicks off of idle and just puttering around.

What I'm wondering is, if I do install the extra down thrust, could i trim out the plane so that the tail would ride lower (sag) and at that attitude, would the plane still be pulled somewhat straight (due to the down thrust)? Which in turn, would give it more lift on the wing since it's not cutting straight through the air but has more incidence to it, in relation to the direction of travel. It may be obvious that I know enough to be dangerous but I think about things like that.

ANY info is greatly appreciated.
